Abstract
In the wireless sensor network, several sensor devices are distributed in an environment with a goal to collect data and then forward it to a base station which could be then later used for some study such as changes in the environment. They are distributed across environment and are fitted with a battery. Due to their small size the size of battery is also small. Several protocols are designed to reduce the energy consumption to improve the network life. One of the famous protocols is Low Energy Adaptive Clustering Hierarchy (LEACH). In this paper, our main focus is to make changes to the original LEACH protocol to reduce energy consumption. We designed two algorithms: Modified Multihop (MMH) LEACH and Modified Cluster Head (MCH) LEACH. Both the algorithms perform better than the original LEACH protocol in terms of remaining energy. Network life is also improved when they were distributed in a bigger environment. The energy consumption is reduced than the original LEACH protocol.
