Life Time Enhancement Techniques in Wireless Sensor Network: A Survey

This paper is survey about life time enhancementtechniques used in wireless sensor networks. In wireless sensor network the lifetime of network is more concentrated area for researchers. Many factors are taken into account for the maximization of life time of wireless sensor networks, such as minimizing the power consumption, low cost operation, optimal routing algorithms, forwarding of residual power to every node to avoid the abbreviating of power in nodes, using improved version of protocols and also communication models , In the past few decades the fast explosive growth in the wireless sensor application needs a substantial modification in the infrastructure of networks. This study show the result of the techniques and hindrance present in the techniques Keywords-Star Algorithm, Distributed Algorithms, Delay-Tolerance, Fuzzy Approach, Mobile Sink Node, Probabilistic scheduling controller, Wireless Sensor
