Abstract

In this paper, we address the problem of routing in urban Vehicular ad hoc networks (VANETs) using the proactive Optimized Link State Routing (OLSR) protocol. OLSR selects MultiPoint Relays (MPRs) according to neighbors' reachability index while Quality-of-Service OLSR (QoS-OLSR) for highway VANET considers bandwidth, velocity and distance for MPR selection. For urban VANET, several reactive and position-based protocols were proposed using mobility metrics such as velocity and distance. Both QoS-OLSR and urban VANET protocols depend on basic mobility metrics which rapidly change due to environment restrictions; intersections and street topology. Our proposed street-centric QoS-OLSR protocol for urban VANET is considered as the first attempt to use an urban-based QoS metric for OLSR MPR selection. Link and street centric parameters such as bandwidth, street and lane are utilized in the proposed protocol. Simulations are conducted using the modified NS3 OLSR's implementation to incorporate the QoS metric. Simulation results demonstrate that our proposed QoS-OLSR improves throughput, Packet Delivery Ratio (PDR), average hop count and end-to-end delay compared to OLSR in urban VANET.
