Abstract? In this paper we have studied few technologies related to the lifetime enhancement of wireless sensor network. The lifetime of wireless sensor network is a critical factor that needs to be addressed by considering different parameters that affect the lifetime of wireless sensor network. The lifetime of the WSN mostly depends on energy consumption by node. The enhancement of network lifetime is carried out by considering different parameters including duty cycle management, network coding, cluster head selection, routing and selection of topology. Each method has its advantages and disadvantages. In the duty cycle management approach the energy efficiency of network increases but there is no provision for packet latency. In network coding approach packet latency is considered but efficient routing algorithm is not introduced. This leads us to couple the advantages of various methods for lifetime optimization and provide an efficient solution for lifetime optimization.
