Wireless distributed sensor networks (WDSN) consists of numerous sensors, deployed at high density in regions requiring surveillance and monitoring. Researchers are currently resolving different technical aspects such as energy efficiency, network lifetime, scalability, load balancing etc. of this distributed network based on different applications.(More)
For a quadrotor, one can identify the two well-known inherent rotorcraft characteristics: underactuation and strong coupling in pitch-yaw-roll. To confront these problems and design a station-keeping and tracking controller, dynamic inversion is used. Typical applications of dynamic inversion require the selection of the output control variables to render(More)
—Wireless mesh networks (WMNs) consist of mesh clients that can be either stationary or mobile, and static mesh routers through which the clients communicate with each other and with the Internet or other networks. Wireless mesh networks have established their presence with a promise of supporting variegated traffic ranging from real-time to best-effort(More)
This work presents a method for online path planning based on graph traversal for autonomous mobile systems. A method using the Voronoi diagrams of obstacle dense areas for efficient planning is proposed. This method creates collision free paths for the vehicle in a receding horizon fashion on a per time-step basis, for environments where no prior map data(More)
A mobile adhoc network (MANET) is formed by a group of wireless mobile hosts or nodes without any fixed infrastructure. As there is no central control in a MANET, a mobile node itself acts as a router. A MANET may function in a stand-alone fashion or may be connected to the Internet. Undoubtedly, MANETs play a critical role in situations where a wired(More)

The success of self configuration in autonomic distributed systems depends on the availability of the management components and their interconnections. This paper describes a fault tree model to evaluate the availability of a tiered autonomic system that considers the failures of management components. The model predictions will guide the selection and(More)
