Simulation and laboratory test performance evaluation results (project Netadded, New Technologies to Avoid Digital Division in e-divided areas)

Abstract : This document provides the performance analysis of the developed intelligent wireless mesh networking protocols according to the definition of tests given in AD02. According to the Technical Annex of Net-added project, the objective of WP 4.3.2 was defining, developing and evaluating new and more flexible algorithms dedicated to wireless mesh network operation. Both SABU and UBP investigated methods to estimate the residual bandwidth in wireless mesh networks. The residual bandwidth is defined as the difference between the network link/path capacity and the current throughput of the system. The proposed SABU algorithm is a passive estimation algorithm, which listens to the channel and uses analytical techniques to calculate the residual channel bandwidth. On the contrary, the proposed UBP method is an active algorithm which injects dummy packets into the channel to saturate the channel and thus, determine the channel capacity accordingly.The performance evaluation of passive algorithm is performed by realistic simulations on OPNET network simulator. The active algorithm is first verified on NS-2 network simulator, and later, it is implemented on LiveNode hardware platform developed by CEMA and UBP under NETADDED project. The LiveNode platform was especially developed for agricultural and environment monitoring applications. Both algorithms were tested with extensive numerical simulation experiments and they are shown to have much better accuracy than those previously proposed in the literature. The performance gains with intelligent networking applications using residual bandwidth as their decision metric are also demonstrated to be significant.
