AODV ================================================ She presents an Implementation for MAC protocol for WSN Application She claims that the existing MAC protocol unable to support WSN applications that require deterministic data transport performance. She aims to develop a MAC protocol delivering data to the sink with node2node bounds on delay She implements a new WSN MAC protocol that is able to give deterministic bounds for message transfer delay and reliability. The protocol is implemented on TinyOS 2.x for a Tmote Sky node using the CC2420 transceiver. the protocol is based on TDMA & retransmission. the protocol shows that a deterministic MAC protocol with reasonable energy consumption patterns is practical.

With variable sensing range, the difficulties to cover a continuous space in the area coverage problem becomes excep- tionally harder than covering discrete points in the target (or point) coverage problem. Very few papers have paid effort for the former problem. Wang and Medidi have solved the area coverage problem based on Delaunay triangulation structure [2]. However, due to the boundary effect their proposed algorithms cannot always provide complete surveillance for the whole network. In this work, we improve the work in [2] so that the monitored area can be completely covered. A theorem confirms that our improved algorithm provides complete coverage for all the cases. In addition, the simulation further shows that our energy-efficient algorithm has an obvious improvement on coverage status with very small compensation of network lifetime. 1 Coverage is a fundamental problem in wireless sensor networks since sensors may be spread in arbitrary manner. In this paper, we addressed the k-support coverage problem. Most of the existing works assume that the coverage degree is 1, i.e. every point in a certain path falls within the sensing range of at least one sensor node. In this work, we focus on the case when we require that every point on the path is covered by at least k sensors, while optimizing certain objectives. We give an optimal polynomial-time algorithm and prove that the time complexity of our algorithm is O(k2n2). To the best of our knowledge, this is the first polynomial time algorithm finding an optimum kcoverage path in sensor networks with general sensing radius and general k we propose an integrated cross-layer data reporting scheme focusing on communication protocols in wireless sensor networks. The scheme operates based on the various application demands and available resources to provide an adaptive quality of service (QoS). The goal of this work is to achieve the expected information quality at the end system by efficiently controlling data reporting functions in communication layers considering parameters from other layers. The main work of this paper focuses on the QoS-aware data reporting tree construction scheme, called QRT, and the QoS-aware node scheduling scheme, called QNS. QRT constructs a data reporting tree based on the conditions of the end-to-end delay and the traffic load to find data reporting paths from each cluster head, which has already collected data from its cluster members, to a sink. QNS schedules a certain number of nodes that are selected based on the QoS requirements in a cluster to report data to its cluster head in a collision-free manner. Simulation results show that these schemes provide good throughput performance while providing stable data reporting that is not affected by network density. we present a practical wireless sensor network for environmental monitoring (OceanSense) deployed on the sea. The system is mainly composed of TelosB motes, which are deployed on the surface of the sea collecting environmental data, such as temperature, light and RSSI from the testbed. The motes communicate with a base station, which transmits collected data to a visualization system running on a database server. The data can be accessed using a browser-based web application. The OceanSense has been running for more than half a year, providing environmental monitoring data for further study.

Unlike typical adaptive middleware approaches, in which sophisticated component model semantics are embedded into an existing, underlying platform (e.g., CORBA, COM, EJB), we propose a platform that imposes minimal constraints for greater flexibility. Such a tradeoff is advantageous when the platform is targeted by automatic code generators that inherently enforce correctness by construction. Applications are written as simple, single-threaded programs that assemble and monitor a set of distributed components. The approach decomposes applications into two distinct layers: (1) a distributed network of interconnected modules performing computations, and (2) constructor logic that assembles that network via a simple block-diagram construction API. The constructor logic subsequently monitors the configured system via a stream of high-level events, such as notifications of resource availability or failures, and consequently provides a convenient, centralized location for reconfiguration and debugging. The component network is optimized for performance, while the construction API is optimized for ease of assembly. Abstract?Presence, broadly defined as an event publishnotification infrastructure for converged applications, has emerged as a key mechanism for collecting and disseminating context attributes for next-generation services in both enterprise and provider domains. Current presence-based solutions and products lack in the ability to a) support flexible user-defined queries over dynamic presence data and b) derive composite presence from multiple provider domains. Accordingly, current uses of context are limited to individual domains/organizations and do not provide a programmable mechanism for rapid creation of context-aware services. This paper describes a presence virtualization architecture, where a Virtualized Presence Server receives customizable queries from multiple presence clients, retrieves the necessary data from the base presence servers, applies the required virtualization logic and notifies the presence clients. To support both query expressiveness and computational efficiency, virtualization queries are structured to separately identify both the XSLTbased transformation primitives and the presence sources over which the transformation occurs. For improved scalability, the proposed architecture offloads the XSLT-related processing to a high-performance XML processing engine. We describe our current implementation and present performance results that attest to the promise of this virtualization approach. Abstract?Accurate, simple and affordable methods for passive indoor tracking of human beings are still missing. In this article, we describe the development of an unobtrusive two-dimensional human positioning system based on low-frequency electric fields. The systemfs operation is based on measuring the capacitance between multiple floor tiles and a receiving electrode. The presented system is invisible to the user and uses a single-chip solution to measure the capacitances. The implemented system is evaluated with two different types of receiving electrodes and the results are presented. With the used tiles, the system can locate a standing human with at least 15 cm accuracy and track a walking person with at least 41 cm accuracy. The update rate of the system is 10 Hz.

We present uWave, an efficient recognition algorithm for such interaction using a single three-axis accelerometer. Unlike statistical methods, uWave requires a single training sample for each gesture pattern and allows users to employ personalized gestures and physical manipulations. We evaluate uWave using a large gesture library with over 4000 samples collected from eight users over an elongated period of time for a gesture vocabulary with eight gesture patterns identified by a Nokia research. It shows that uWave achieves 98.6% accuracy, competitive with statistical methods that require significantly more training samples. Our evaluation data set is the largest and most extensive in published studies, to the best of our knowledge. We also present applications of uWave in gesture-based user authentication and interaction with three-dimensional mobile user interfaces using user created gestures. FollowMe! Mobile Team Coordination in Wireless Sensor and Actuator Networks Stephan Bosch, Mihai Marin-Perianu, Raluca Marin-Perianu, Hans Scholten, Paul Havinga Autonomous vehicles are used in areas hazardous to humans, with significantly greater utility than the equivalent, manned vehicles. This paper explores the idea of a coordinated team of autonomous vehicles, with applications in cooperative surveillance, mapping unknown areas, disaster management or space exploration. Each vehicle is augmented with a wireless sensor node with movement sensing capabilities. One of the vehicles is the leader and is manually controlled by a remote controller. The rest of the vehicles are autonomous followers controlled by wireless actuator nodes. Speed and orientation are computed by the sensor nodes in real time using inertial navigation techniques. The leader periodically transmits these measures to the followers, which implement a lightweight fuzzy logic controller for imitating the leaderfs movement pattern. The solution is not restricted to vehicles on wheels, but supports any moving entities capable of determining their velocity and heading, thus opening promising perspectives for machine-to-machine and human-to-machine spontaneous interactions in the field.

Prototype shows WSANs can automatically sense limitation velocity integration accumaulates error A Novel Communications Protocol Using Geographic Routing for Swarming UAVs Performing a Search Mission Robert Lidowski, Barry Mullins, Rusty Baldwin Initial Location/sensor type no signif effect Geogr forwarding waypoint reservation degrad perform USMP This paper develops a novel communications protocol for autonomous swarms of unmanned aerial vehicles (UAVs) searching a 2-dimensional grid. The search protocol, the UAV Search Mission Protocol (USMP), combines inter-UAV communication with geographic routing to improve search efficiency in terms of total searches, distance traveled by UAVs, and the minimization of UAV direction changes. By determining where search state updates impact search decisions, messages are geographically routed to improve search efficiency. USMP and the geographic greedy perimeter stateless routing (GPSR) protocol are studied via simulation using OPNET Modeler 12.0. Geographic routing degrades performance by at least 20% in total searches and distance traveled, but improves direction changes by 6.7%. Overall, USMP improves performance by as much as 188% compared to scenarios without inter-UAV communication. A Policy-Based Management Architecture for Mobile Collaborative Teams Eskindir Asmare, Anandha Gopalan, Morris Sloman, Naranker Dulay, Emil Lupu Many missions are deemed dangerous or impractical to perform by humans, but can use collaborating, self-managing Unmanned Autonomous Vehicles (UAVs) which adapt their behaviour to current context, recover from component failure or optimise performance. This paper describes a policy-based distributed self-management framework for both individual and teams of UAVs. We use three levels of specifications ? policy, mission class and mission instance to enable reuse of both policies and mission classes. The architecture has been tested on devices ranging from small laptops to body area networks. Initial evaluation shows the distributed architecture is scalable and outperforms a centralised mission management scheme.
