Abstract :
In a randomly deployed wireless sensor network coverage is a fundamental issue to monitor the region of interest without leaving any area unmonitored. With limited battery of a senor node this poses a big challenge. One way to maintain good coverage and extend the network lifetime is to deploy sensors in high density and schedule them to sleep between active cycles. In this paper, we propose an algorithm to schedule the sensor sleep based on the area of overlapped coverage with neighboring sensors. First Euclidean distance of the nodes based on which the nodes placement in the intended coverage area is determined then overlap nodes are determined, multiple nodes with similar sensing range will go to sleep mode thereby keeping only one node in the active state. Simulations results show that this algorithm achieves better performance in terms of coverage efficiency than PEAS algorithm.

Key-Words / Index Term :
