Research Area:  Vehicular Ad Hoc Networks
Reliable communication is always one of the requirements of vehicular ad-hoc networks (VANETs). However the high speed mobile nodes and dynamic topology structure of VANETs means it is difficult to get a stable link between vehicles. Toward this end, we propose an optimized mobile similarity and link transmission quality routing (OMSLTQR) to select routing nodes and maintain the quality of communication link. Mobile similarity and link transmission quality are two basis for routing selection. To get the speed information for mobile similarity calculation, we modify the frame structure. The local information frame is redesigned to save and transmit link selection information. We also propose an algorithm based on OMSLTQR to find the routing neighbor set. Simulation results shows that our OMSLTQR achieves better system performance than optimized link state routing in terms of end-to-end delay and successful transmission rate.
