Mobility Aware Efficient Location based Routing Protocol for Vehicular Ad Hoc Networks

The Vehicular Ad Hoc Networks (VANETs) also known as subclass of Mobile Ad hoc Networks (MANETs), however the routing methodologies designed for MANET practically proven inefficient because of high mobility& network area characteristics of VANET communications. Thus, the position based routing protocols is alternative technique to address the challenges in VANET communications. Number of position based routing protocols recently proposed for VANET communications. This research proposed novel location based routing protocol by considering the key parameters of selecting the next relay node such as mobility speed, geographical distance and packet relying characteristics. To optimize the route establishment process, we perform the position based route establishment tasks using Ant Colony Optimization (ACO). The ACO forwards several ants towards the destination vehicle, which is the closest one to the destination vehicle. While selecting the next hop, ACO accesses the packet relaying quality and mobility speed of vehicle in order to generate more efficient and stable data transmissions in network. The proposed location based protocol is called as Mobility Aware VANET using ACO (MAVA). The simulation results of MAVA compared with the recent location based protocols in terms of throughput. The outcome demonstrates the efficiency of MAVA.
