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 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 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 کاملA Survey of Black Hole Detection Techniques in WSNs
Wireless Sensor Networks (WSN) is a trending technology now-a-days and has a wide range of applications such as battlefield surveillance, traffic surveillance, forest fire detection, flood detection etc. But wireless sensor networks are susceptible to a variety of potential attacks which obstructs the normal operation of the network. Black hole attack is one of severe security threat that affec...
متن کاملA Decentralized Method for Maximizing k-coverage Lifetime in WSNs
In this paper, we propose a decentralized method for maximizing lifetime of data collection wireless sensor networks (WSNs) by making minimal number of nodes operate and putting other nodes in sleep. We divide a target field into multiple grids and make nodes in each grid locally achieve k-coverage. We can reduce energy consumption of WSN by minimizing the number of active nodes required for kc...
