Designing Multi-Hop Energy Efficient Routing Protocol for Large Scale Wireless Sensor Network

Abstract

In Wireless Sensor Network (WSN) sensors will collect reliable data from distant setting and send this data for the base station to notice a happening from the environment. Sensors are units deployed arbitrarily within the environment with restricted energy for sensing many environmental parameters. In most cases their battery isn't rechargeable or replaceable. To optimize their existing energy routing protocols play a vital role. This thesis proposes Multi-Hop Energy Efficient Routing Protocol (MH-EERP) for WSN. The proposed protocol is used for wireless sensor network to enhance the lifespan of the network by decreasing energy consumption of sensor nodes. In the proposed method, sensor nodes are deployed randomly within the sensing area and incorporated into some clusters based on their local density, distance and remaining energy of each node. After clusters are formed, multi-hop routing scheme between intra-cluster and inter-cluster communications for better energy utilization in large-scale wireless sensor network is proposed. The proposed protocol improves the recent existing multi-hop routing approaches which are Cluster-Based Multi-Hop LEACH and Improved Multi-Hop LEACH by modifying cluster head selection method and sensor node placement near to the BS for inter-cluster communication and near to the cluster head for intracluster communication. The proposed work simulates by using MATLAB simulator on different network size and compared with the existing protocols to analyze the performance of each protocol. Simulation result shows that the proposed approach improves the overall performance in terms of the number of alive nodes, residual energy, packets sent to the BS and number of dead nodes per a round over the existing protocols.
