VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play animportant role in public safety communications and commercial applications. Routing of data in VANETsis a challenging task due to rapidly changing topology and high speed mobility of vehicles. Positionbased routing protocols are becoming popular due to advancement and availability of GPS devices. Oneof the critical issues of VANETs are frequent path disruptions caused by high speed mobility of vehiclethat leads to broken links which results in low throughput and high overhead . This paper argues the useof information on vehicles’ movement information (e.g., position, direction, speed of vehicles) to predict apossible link-breakage event prior to its occurrence. So in this paper we propose a Reliable DirectionalGreedy routing (RDGR), a reliable position based routing approach which obtains position, speed anddirection of its neighboring nodes from GPS. This approach incorporates potential score based strategy,which calculates link stability between neighbor nodes in distributed fashion for reliable forwarding ofdata packet. |
