One issue in wireless sensor networks is achieving efficient operation because of the limited available power. Energy efficient transmission is of vital importance in the design of wireless sensor networks (WSN). Balancing energy consumption and prolonging network lifetime is the main aim of this paper. Energy efficiency is a primary concern in the design of algorithms and protocols for wireless sensor networks. In the research field of WSNs how to reduce the energy consumption of WSN so that the lifetime of WSN can be prolonged is one of the hottest spots. We focus on different techniques to reduce the consumption of the limited energy budget of sensor nodes. After having identified the reasons of energy waste in WSNs, we have implemented the strategies to enhance the lifetime of wireless sensor network. We have implemented four existing protocols namely, Directed Diffusion protocol, LEACH protocol, LEACH with TREE and TREEPSI protocols and proposed two protocols named as Novel1 protocol and Novel2 protocol which are implemented in NS2. We have compared LEACH protocol with Novel1 protocol and TREEPSI protocol with Novel2 protocol to show that proposed protocols improves the performance of wireless sensor network. Experimental results showed that the proposed protocols are more efficient than existing protocols through which lifetime of wireless sensor network is enhanced.
