Route and Load Aware Channel Assignment Algorithm for Multichannel and Multi Radio Vehicular Ad-Hoc Networks
Vehicular Ad-hoc Network (VANET) is a special type of Mobile Adhoc Network (MANET) technology that recently gained lot of prominence in urban areas. VANETs consider a combination of Road Side Units (RSUs) and vehicles with wireless radios. One primary issue in VANET is Medium Access Control (MAC), which aims to utilize the radio spectrum efficiently, to resolve potential contention and collision among vehicles for using the medium. Contention reduces the performance of single channel MAC protocols and the workload distribution among the vehicles is also not well defined. Hence Multi channel Multi radio architecture is useful to provide better quality of services (QoS). But here multi channel interference is a major problem to assign channel to a particular vehicle. The proposed work describes a cross layered approach with distributed channel assignment algorithm. The multipath routing is carried out with the help of a distributed channel assignment algorithm to assign channels to each vehicle by finding out each channel load. This route and channel load aware algorithm provides better quality of service in VANET. Simulation results reveal that, Weighted Cumulative Expected Transmission Time (WCETT) routing metric in multipath routing algorithm integration with multi channel and multi radio outperforms AODV and DSR in various QOS parameters.
