Impact of Duplicates in Energy Consumption of Wireless Sensor Networks Using the GSP Protocol

Abstract

Wireless sensor networks which employ a routing protocol from the Flooding family are often assumed to waste a great amount of energy generating duplicate packets [1].Simulations were conducted showing that the assumption is not true for one member of the flooding family, the Gossip-based Sleep Protocol (GSP) [2]. Simulation results show that the performance of GSP in 100-node square grid networks eliminates the risk of packet explosion while retaining the benefits of a flooding protocol. The paper also presents a novel energy consumption analysis, revealing that the majority of energy is used for idle listen, when there are no packet transmissions.
