Hole Detection and Healing for Improving Coverage in WSNs
A Wireless Sensor Network (WSN) consists of a large number of randomly deployed sensor nodes. These sensor nodes arrange themselves into a cooperative network and perform the three basic functions of sensing, computations and communications. Wireless sensor networks (WSNs) are increasingly being used to track objects and monitor various phenomena or region of interest (RoI), where the main task...
متن کاملModified Coverage Hole Detection Algorithm for Distributed WSNs
32 32 Abstract— Wireless sensor networks (WSNs) are spatially distributed sensors that find wide applications in various fields such as environmental control, Medicine and Health care, Military surveillance etc. The sensing and communication within the network should be effective for such applications. Holes are the voids created in the network when accidental death of nodes is caused due to te...
متن کاملAn Efficient Recovery Algorithm for Coverage Hole in WSNs
Failures are inevitable in wireless sensor networks, and it is important to detect and patch the “coverage hole”. In this paper, we propose an efficient recovery algorithm based on minimum distance redundant nodes. By numerical algorithm, the sink node gets the centre of the “coverage hole”, and then wakes up a redundant node, which has the minimum distance to the centre, to recover the hole. S...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولAn energy-efficient hole-healing mechanism for wireless sensor networks with obstacles
In wireless sensor networks (WSNs), coverage of the monitoring area represents the surveillance quality. Since sensor nodes are battery powered and placed outdoor, there will be failures due to energy exhaustion or environmental influence, resulting in coverage-loss. In literature, a number of studies developed robot repairing algorithms that aim at maintaining full coverage. However, they did ...
