A New Energy-efficient Multi-hop Routing Protocol for Heterogeneous Wireless Sensor Networks

Research Abstract

Major goals of routing optimization approaches for heterogeneous wireless sensor networks (HWSNs) are to optimize the use of sensor nodes' power and prolong the lifetime of HWSNs. Most routing techniques work on WSNs with static nodes, so node positions are known, and once formed, the cluster remains constant throughout the network's lifetime. However, the challenge with WSN dynamic node positions is that node positions change dynamically, requiring cluster formation changes and routing techniques to handle node positions. In the proposed multi-hop routing protocol using moving HWSNs nodes.The challenge is to dynamically control cluster formation and CHs selection so that the routing protocol can deal with changes in node location and energy. A new energy-efficient multi-hop routing protocol for HWSNs with sensor node mobility is proposed, with the main goal of improving HWSNs performance by minimizing energy consumption, extending network lifetime, and eliminating redundancy in sensor data to improve throughput.
