Performance Analysis of XOR-Based Routing Protocols in Vehicular ad hoc Networks

Research output: Chapter in Book/Report/Conference proceedingChapter


The routing strategy is an important issue in Vehicular ad hoc Networks since the shared nature of the wireless medium, the time-varying capacity of the links and the highly dynamic network topology due to vehicles’ mobility severely restrict the choices available for the creation of the paths. These issues influence the availability of the path and its long-term duration. In this paper we present a performance analysis of XOR1-based flat routing pro- tocols in high mobility conditions, considering a vehicular ad hoc network (VANET) formed in a highway scenario. First, we propose an XOR-based protocol that incor- porates several adaptations of the existing XOR-based routing algorithms, in order to cope with the network mobility. Then we propose an improved version of it, XORi, which modifies the protocol’s information gathering process to accommodate the specific dynamic nature of VANETs topology. Finally, we evaluate the performance of XOR-based protocols with other topology-based routing protocols. Simulation results allow us to characterize the performance of this class of protocols through the comparison of the packet delivery ratio, end-to-end path delay and average number of path hops. When a moderate density of nodes is considered, simulations show that XOR-based algorithms achieve almost the same packet delivery rate as link state algorithms, such as OLSR, while for high density of nodes XOR-based algorithms scale better in terms of delay when compared to source routing algorithms, such as DSR.
