Modified RCH-LEACH (MRCH) for Wireless Sensor Networks (WSN)

The prime objective of WSN is to carry out the exchange of information using optimized amount of energy. WSN uses various clustering methods to route the information among the randomly deployed sensor nodes. Here, the primary role of nodes is to sense the surrounding information (data). In different clustering approaches, the Cluster Head (CH) selection will be a critical process in saving the node’s as well as the network energy. The different parameters have been utilized for important roles in the CH selection as energy efficient. Here, we are presenting a modification in the already published algorithm called RCH-LEACH and known as MRCH for producing it as extra energy efficient. For the CH selection, the modified algorithm used the energy of alive nodes as one of the deciding parameters for choosing the percentage of nodes that will provide the optimal number of CH for efficient usage of energy. MRCH enhances the network lifetime against the same as of the RCH-LEACH and other similar algorithms. MRCH performance is equally good in terms of residual energy. MRCH has also been analyzed under the different scenarios of placement of Base Station (BS).
