A Performance Comparison of Data Dissemination Protocols for Wireless Sensor Networks

In recent years a variety of new data dissemination protocols have been developed specifically for Wireless Sensor Networks (WSN), but no realistic performance comparison between them has been attempted. This paper reports on the results of a simulation comparison made by an independent researcher using the ns-2.26 simulator for the WSN protocols: Directed Diffusion (DD), Two-Tier Data Dissemination (TTDD) and GRAdient Broadcast (GRAB). Their performance study provides useful insights for the network designer - such as which protocols (and design choices) scale control traffic well, improve data delivery or reduce overall energy consumption.
