A Comparative Analysis of Low Energy Adaptive Clustering Hierarchyand Power Efficient Gathering in Sensor Information System Progressive Conventions

Abstract

A Wireless Sensor Network (WSN) is a web of sensors installed in a random fashion over an area that monitors the physical environmental conditions and parameters like pressure, temperature and moisture. The sensor nodes initially fetch the data from the immediate surroundings which is then aggregated in order to send it to the base station or the sink node. As sensors characteristically are resource-constrained in nature, reducing the energy consumed by the node becomes a challenge. The process used to transfer data from a source to what is known as a route protocol. The three types of succession channels are flat protocols, high-level and local-based protocols. Numerous studies have shown that high-speed traffic improvements improve tracking protocols in terms of deterioration and energy efficiency. Two factors namely energy efficiency and network life time play a very important role in determining the efficiency and capability of the route protocol. In this paper, we emphasize two such principles - LEACH and PEGASIS. In the LEACH protocol, the sensor nodes restructure themselves into groups called clusters and each of these structures are designated with a cluster head node. On the other hand, PEGASIS uses a technique where each individual sensor node communicates solely with its respective neighbour node and inherently. PEGASIS facilitates a chain-based communication structure where turns are taken by each node to transmit data to the base station. In this paper, comparisons between LEACH and PEGASIS protocols are based on network characteristics such as power consumption, packet delivery rate, transmission delays, passing, high percentage and dead node.
