Assisted-Leach (A-Leach) Energy Efficient Routing Protocol for Wireless Sensor Networks

Sunkara Vinodh Kumar and Ajit Pal
Abstract—The nodes in a wireless sensor network have limited energy and hence, lifetime maximization is the prime task during protocol design. Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is a benchmark Clustering Protocol which imposes upon cluster heads the complete load of aggregation and relay of messages to base-station. Our protocol Assisted LEACH (A-LEACH) achieves lessened and uniform distribution of dissipated energy by separating the tasks of Routing and Data Aggregation. It introduces the concept of Helper Nodes which assist Cluster Heads for Multi-hop Routing. A new algorithm has been formulated to facilitate energy efficient Multi-hop Route Setup for helper nodes to reach base station. The proposed protocol extends the lifetime of the network, minimizes overall energy dissipation in the network and distributes dissipation among Cluster Heads, Sensor Nodes and Helper Nodes vis-´a-vis LEACH. This is substantiated by simulation results.

Index Terms—Clustering protocols, energy-efficient protocol, leach, multi-hop, routing protocols.
