Comparative Analysis of LEACH Network Routing Protocol in Wireless Sensor Networks: A Survey

WSN having not a fixed architecture randomly deploys numerous sensing nodes over any measuring area and the collected information are sent to the head nodes through wireless media. In the area of lifetime of sensing elements as it is placed in uncertain areas or inaccessible zones with limited energy sources where the replacement or recharging of these sensor battery is just tends to impossible researches are working. Hence, researchers are trying to design a routing protocol that can effectively use the resources of sensor nodes. Low-energy adaptive clustering hierarchy (LEACH) have come up with several successors from distributed clustering to centralized clustering, single- hoping to multi-hoping, normal power source to renewable energy based etc. This survey paper is based on the LEACH and its successors. Primary focus of our examination is the manner by which these all-inclusive conventions operate in the request to increase the survival period and in what way quality steering conventions are developed for wireless sensor networks. Moreover, this paper features a portion of the issues considered by LEACH and furthermore clarifies how problems are controlled by the expanded variants of LEACH.
