Abstract: Wireless sensor network have important applications in target coverage and monitoring. Now a day the development in wireless communication system led to low power and low cost wireless sensor network. The key requirement to design a network protocol is to maximize network lifetime and low power consumption. Wireless sensor network comprise of tiny sensor nodes. The nodes are sense the information, compute it and communicate to the neighbour nodes. To improve the performance of the network many optimization techniques are present. In this paper we discus different optimization techniques like PSO, ABC, GA, and ACO, AS.
