A detailed simulation study of geographic random forwarding (GeRaF) in wireless sensor networks

This paper provides a thorough performance evaluation of the GeRaF protocol in a multi-hop wireless sensor network scenario. The contributions of the paper are twofold. First we provide an in-depth discussion on the impact of the different protocol parameters and of network features on the protocol performance. Based on the results of the first part of our investigation we design variants of the basic GeRaF protocol which are able to significantly decrease the packet latency and to increase the packet delivery ratio. The study presented in this paper is the first attempt to thoroughly characterize the performance of GeRaF and is a necessary step toward understanding the real protocol behavior before implementing it on real devices.
