Increasing the Lifetime of Leach Based Cooperative Wireless Sensor Networks

摘要

Energy constrain is the major problem faced by WSN. In this paper LEACH protocol is analyzed. It is shown that distance; initial energy and election probability play a vital role in increasing the lifetime of sensor nodes. This paper implements LEACH in cooperative transmission and analyses its performance in comparison to SISO (Single Input Single Output). It is shown that for large network area cooperative transmission is more successful than SISO as it will consume less energy to transmit data over the large network area.
