The effect of coverage radius of nodes to network lifetime in wireless sensor networks

Abstract

Performance parameters are pretty important as well as clustering and routing algorithm in order for conditioning network lifetime in Wireless Sensor Network (WSN). The parameters like number of nodes, network area and radius of node coverage affects network lifetime directly. In this study the radius of node coverage's effect on network lifetime was checked out on various number of nodes. In the study, simulated by using OMNeT++ program, Heed protocol and K-means algorithm were used and parameters of HEED protocol were based. According to the results obtained, in the simulations made in 100 m×100 m network domain and 50 and 100 count of nodes, it gives the best result in network lifetime when the radius of node coverage is 20 m. It is observed that network lifetime was improved up to 15% between coverage radius of 10 m and 50 m.
