摘要：In Wireless Sensor Network the (WSN) main constraint against the enhanced lifetime of a network is the consumption of energy by the sensor nodes which are basically driven by battery. Extending the effective operating duration of wireless sensor networks remains in the center of attention while talking about wireless sensor network issues. As lifetime is directly related with the energy supplies of the nodes, a robust approach to contribute towards overall network lifetime is to optimize the energy consumption the nodes. At the same time an energy efficient routing protocol is the major concern in field of wireless sensor network. In this paper we present comparison of five energy efficient hierarchal routing protocols, developed from conventional LEACH protocol. We are concentrating in our research how these extended routing protocols work in order to enhance the longevity of the wireless sensor network. Simulation results shows that newly developed fuzzy based LEACH or LEACH-F is able to enhance the lifetime of the network better than any other version of existing LEACH protocol.
