Abstract
The maximizing lifetime of Barrier coverage in wireless sensor network has attracted researchers in recent past. In barrier coverage applications it is essential to prolong the lifetime of sensor networks which guarantees extended operating lifetime of the overall network. In this paper, we propose a novel Tell Neighbor Algorithm (TNA), which increases the operating lifetime of the overall network. Simulation results show that the lifetime obtained by TNA is better than some of the already existing state-of-art algorithms. Lifetime obtained by TNA is doubled when compared already existing algorithms.
Highlights
Coverage in Wireless Sensor Networks (WSNs) has attracted researchers in recent past
Our results show that Tell Neighbor Algorithm (TNA) algorithms give a better operating lifetime of the network compared to imperialist competitive algorithm for barrier coverage (ICABC), Two round maximum flow algorithm (TMFA) and disjoint path algorithm (DPath) algorithms
Results obtained for Tell-Neighbor Algorithm shows its superiority when compared to other stateof-art works in enhancing the lifetime of the network for barrier coverage
Summary
Coverage in Wireless Sensor Networks (WSNs) has attracted researchers in recent past. In general three types of coverage problems exist in WSN, viz, Point coverage, Area coverage and Barrier coverage. Area coverage/full coverage requires sensors to be deployed throughout the area of interest which results in more number of sensors for deployment. Deployed nodes in area coverage need to monitor the complete length and width of the area. Full coverage as given, where every point in the region of interest is covered has a disadvantage in terms of a number of sensors required. As given, is a coverage model where the monitoring parameter is confined to movement detection in the area of interest. Sensor nodes s and t are virtual nodes added to the left and right boundaries of the area respectively
