Quality of Service and Energy Efficient Evaluation of Hierarchical and Flat Routing Protocols for Wireless Sensor Networks

摘要

Wireless Sensor Network (WSN) is a network with limited power sensing devices with a communications infrastructure for monitoring physical or environmental conditions, such as temperature, sound, pressure, etc. Among the concerns of these networks is prolonging the lifetime by saving nodes energy. There are several protocols specially designed for WSNs based on energy consumption and network lifetime. However, many WSNs applications require QoS (Quality of Service) criteria, such as latency and throughput. In this paper, we will compare three routing protocols for wireless network sensors LEACH (Low Energy Adaptive Clustering Hierarchy), AODV (Ad hoc on demand Distance Vector) and LABILE (Link Quality-Based Lexical Routing) using Castalia simulator in terms of energy consumption, number of nodes alive and stability period, throughput and latency time of packets received by the base station under various conditions. The results prove that LEACH had the longest network stability period, consumes the least energy and had the least latency time, while the LABILE and AODV protocols have the highest throughput.
