Mobility Prediction And Node Prediction Based Light-Weight Reliable Broadcast Message Delivery For Vehicular Ad-Hoc Networks

Abstract: VANET is a Vehicular Ad hoc-Network; it can able to communicate between the moving vehicles. The Reliability as well as Efficiency of Transmissions is of a paramount issue for the safety critical services of VANET due to the urgency and/or significance of the messages. The main problem in VANET is data transmission cannot be done in cross street due to some obstacles. To overcome this, existing work proposed „Light Weight Reliable Broadcast Message Delivery‟ mechanism is not effective but, in LWRBMD mechanisms broadcast the Message delivery could be difficult at the intersection zone due to choosing the wrong node and the node will be moving out of zone, which results in packet loss occur. While rebroadcasting is done the Bandwidth will be increased. Thus in our proposed work, we introduce two methods in order to predict the node and mobility. Based on these prediction methods we can improve the energy efficient. Which will decrease the Bandwidth for Packet Forwarding? In Intersection Zone the Packet will be forwarded, which decreases the packet loss and low data rate. Time Complexity Simulation results show that the proposed mechanism can provide similar or better reliability while incurring prominently less overheads than the existing approaches.1
