An Improved LEACH Protocol using Fuzzy Logic in Wireless Sensor Network

Wireless Sensor Networks are group of low cost and extreme power limited sensor nodes. The various applications of wireless sensor networks include sensing the environment to collect the data and send it to the base station or server in single or multiple hops. The basic target of WSN is to achieve maximum network life using the minimum battery power as limited battery backup is available for any WSN. The first part of this paper presents the comparative study of leach protocol and its types. The second part includes a new improvement in LEACH protocol using Fuzzy Logic.
