Re-LEACH: An Energy-Efficient Secure Routing Protocol for Wireless Sensor Networks

Wireless sensor network most knowing topic in the current time. The popularity of wireless sensor network growing very fast because it is low cost devices as well as low energy consumption with higher utilization. Routing protocol is an important part of sensor network. Routing protocols play an important role in the wireless sensor network. LEACH protocol is cluster-based routing protocol. LEACH protocol work on two steps, the first step is setup phase and the second step is a steady phase. In the setup phase, we select the one cluster head in the group of nodes after that come to the steady phase here we aggregate the data or compress the data then send the data to sink node or gateway. In this paper, we propose a new protocol Reappointment LEACH (Re-LEACH) which is more energy efficient than other protocols as well as lighter overhead. Re-LEACH protocol increases the life period of sensor network with low energy consumption.
