A survey on LEACH and other's routing protocols in wireless sensor network

An extensive range of applications of Wireless Sensor Networks such as military, environment, surveillance, home, vehicle tracking/detection, traffic flow and medical make it hot-spot in the epoch of wireless networks. A WSN consisting of numerous sensor-nodes is equipped with inadequate energy, memory, and computation capability issues. Further, such networks are limited to reinstate the dead nodes caused by energy's depletion and to maximize the life-span of the system. To achieve this aim, several routing algorithms are proposed and investigated. In this work, an attempt is carried out to assess the diverse hierarchical routing protocols, developed from LEACH and is extended to other presented routing protocols like TEEN, APTEEN, and PEGASIS. Depending upon the observations and scrupulous consideration, a relative conclusion is drawn in the last. (C) 2016 Elsevier GmbH. All rights reserved.
