Self power analysing energy efficient protocol (SPAEEP): An adaptive approach

Abstract

Main challenge in WSN (Wireless sensor network) faced by researcher is — battery life (energy of a node). In this paper general framework of distributed mechanism of multi-hop WN (wireless network) is considered. Cluster based routing protocols like Low Energy Adaptive Clustering Hierarchy (LEACH), Hybrid Energy Efficiency Protocol (HEEP). Threshold sensitive energy efficient network Protocol (TEEN) and PEGASIS efficiently manages the energy usage. But still these protocol should be thoroughly studied and revised to achieve more energy efficiency. Paper focuses on LEACH protocol, where cluster Head (CH) selection process termed as ‘round’ (r). Each round costs setup and steady state phase of the network. Research proposes novel idea of Self Power Analyzing Energy Efficient Protocol (SPAEEP) with energy model (eM). EM is applied to CH which adaptively decides to initiate next round based on balanced energy. Adaptive decision will help in reducing the number of rounds (r). Application of the same to the nodes will lead to fault tolerant network with proper hand over mechanism. Concept is also extended to 802.15.4 protocol, as it follows standard network architecture. Our results reveal that new method suggested will reduce energy consumption of CH and hence the increased life span of network. The outcome is fault tolerant network.
