Performance Issues of Ad Hoc Routing Protocols in a Network Scenario used for Videophone Applications

Abstract

In ad hoc mobile networks, the user mobility level, the range of possible network scenarios, and the traffic load generated by their typical applications are key aspects that make challenging to select a given routing protocol. In such a context, this paper presents a simulation-based performance analysis of ad hoc routing protocols in a hybrid ad hoc network scenario, which is used by mobile users to estabilish videophone sessions. The average packet delivery rate, end-to-end delay and routing load are measured and evaluated by varying the routing protocols, network range, number of nodes and user mobility.
