Lifetime Improvement of Wireless Sensor Network
The fundamental challenge of a wireless sensor network is to maximize the network lifetime. To overcome this challenge, one of the possible solutions is to find optimal sink location. In this paper, we have introduced relay nodes to mitigate network geometric deficiencies and the Particle Swarm Optimization (PSO) based algorithm has been used to locate the optimal sink position with respect to those relay nodes to make the network more energy efficient The relay nodes are responsible to communicate with the sink instead of the sensor nodes. Experimental results show that our current approach further improves the lifetime of the network.
