Abstract: Number of wireless devices connected via ad hoc networks has been growing exponentially over these years with increased mobility and resource usage. Routing of data packets from the source to the destination device has been a major issue in dynamic wireless networks. Traditional topology based routing protocols suffer from increased mobility in the network and cannot guarantee the expected quality of service. To overcome this issue a new class of highly flexible routing protocols were proposed that opportunistically forward the data packets from one node to the other based on current channel characteristics and mobility. These opportunistic routing protocols utilize the broadcasting nature of the wireless medium to achieve high data delivery in dynamic ad hoc networks. But this high data delivery comes at a cost of increased redundant packets and duplicate data forwarding in the network. Limited research has been done in increasing the efficiency of opportunistic routing protocols in highly dynamic networks. This study aims to improve the efficiency of opportunistic routing protocols in highly dynamic ad hoc networks by eliminating redundant data forwarding at the mobile wireless devices. The proposed method helps to control relaying of data packets at each node in the network on a per packet basis using information piggybacked on each packet. Simulation results show that the proposed method reduces duplicate data forwarding considerably in the network leading to higher efficiency in opportunistic routing.
