Route duration improvement in wireless sensor and actuator networks based on mobility parameters and flooding control

摘要

Mobility of nodes is one of the main causes of broken links in wireless networks. Although several theoreticalmodels for links and routes selection have been proposed in the literature, so far little effort has been made toapply them to the existing routing protocols. In this article, a decision tree has been incorporated in a reactiverouting protocol in order to select the most long-lived routes. The decision tree is based on nodes’mobilityparameters typically considered by the theoretical models, such as distance between nodes, relative speed, andnodes’directions. The flooding techniques used within the routing protocols for the routing discovery procedurescause a massive usage of control packets which in turn has negative impact on the performance of the networks.So, an improved flooding control is presented in this article that enhances the performance of the proposed routeselection based on a decision tree, in turn reducing overheads and the power consumption caused by the controlpackets. These two proposed approaches have been implemented over a widely used reactive routing protocolsuch as Ad Hoc On-Demand Distance Vector (AODV) to obtain performance results using Network Simulator 2simulation tool. The performances of the proposed approaches have been compared with that of the AODVimplementation in terms of general performance and path duration. The simulation results show that theproposed route selection significantly improves the results of AODV
