Connectivity based geographical opportunistic routingprotocol for vehicular Ad hoc networks
一种基于连接性的VANETs地理机会路由协议

The road topology restrictions and rapidly moving vehicular cause intermittent connectivity in VANET. To this point, this paper took advantage of the navigation path and connectivity on the path, and dynamically selected the vehicle with the minimum expected delay metric to delivery data. Based on the metric, it proposed CGOP(connectivity based geographical opportunistic routing protocol). The simulation results show that CGOP outperforms GeOpps and GPSR in terms of average data delivery delay and packet delivery ratio, and superior robustness to intermittent connectivity conditions in VANETs.
