Abstract—Without any infrastructure MANETs need to utilize the broadcast or multicast modes to transfer efficiently packets between wireless nodes. However, broadcast may easily cause a broadcast storm in the wireless networks, which will lead to network congestion and make the normal packets cannot be transferred. This paper tries to combine the advantages of location-aware distributed cluster algorithm and MAOVD schemes to improve the transmission efficiency and the throughput of MANET in geographic routing protocols. We also identify the problems in broadcast storm and bandwidth wasting problems that could be improved by using the design of our LDCA routing protocol for wireless ad-hoc networks.
