Coverage Hole Avoidance Using Fault Node Recovery in Mobile Sensor Network

Authors(3) :-A. Sri Chamundeswari, P. Kesavini, P. Sachidhanandam

Sensor nodes are prone to failure due to energy reduction and some other reasons in Distributed Sensor Networks (DSNs). The coverage and energy utilization control in mobile heterogeneous wireless sensor networks (WSNs) are analyzed. The term heterogeneous mean that sensors in the network have various sensing radius, which is an inherent property of many functional WSNs. Two sensor deployment schemes are considered uniform and Poisson schemes. The main focus of this work is directed towards distributed coordination algorithms for coverage in a mobile sensor network. The sensors are assumed to have non identical sensing ranges, and it is desired to move them in such a way that the total sensing coverage increases as much as possible. Towards the end, the field is partitioned using the multiplicatively weighted voronoi cells, and then different geometric methods are developed to find new locations for the sensors such that the coverage is improved. The proposed algorithms are iterative, and use the existing local information to place the sensors accurately, aimed to decrease the size of the coverage holes in the system. The scheme proposes a defective node recovery and replacement algorithm for WSN based on the grade diffusion algorithm combined with genetic algorithm. The Fault Node Recovery (FNR) algorithm requires replacing smaller number of sensor nodes and reuses the most routing paths, rising the WSN lifetime and reducing the replacement rate. The proposed algorithm increases the number of active nodes and reduces the rate of energy utilization.
