An improvement of route duration in WSAN based on nodes´ mobility and RSS

Although several theoretical models for links and routes selection have been proposed in the literature, little effort has been made to apply them to routing protocols. In this paper a decision tree has been incorporated into the routing protocol in order to select the most long-lived routes. The decision tree is based on several assumptions which take into account the most relevant parameters considered by the theoretical models, such as distance between nodes, relative speed, and nodes´ directions. The proposed approach has been implemented over a reactive routing protocol as Ad Hoc On-Demand Distance Vector (AODV) to obtain performance results using Network Simulator 2 simulation tool. The performance of the proposed approach has been compared with the traditional AODV implementation in terms of path duration.
