Abstract:

In VANET, the found link is easy to break due to the high mobility of node and the impact of road. Routing is the key factor of implementing VANET. Link stability is an important factor that evaluates the performance of routing algorithm. This paper proposes a calculation method of link stability based on the connectivity probability to measure the robustness and reliability of the link. Experimental results show that the method is applicable to the VANET.

Key words: VANET;link stability;connectivity probability of link
