摘要：Opportunistic routing overcomes most of the issues and challenges faced by traditional topology based routing protocols in highly mobile ad hoc networks. Opportunistic routing alleviates the impact of poor transmission links in wireless networks by making use of the broadcast nature of the wireless medium and path diversity. In opportunistic routing a list of candidate nodes are selected and prioritized using a metric calculated dynamically from the network. When a data packet is transmitted, the candidate nodes coordinate and select one best forwarder to forward the data packet towards the destination. This opportunistic forwarding strategy continues till the packet reaches the destination. In recent times a number of opportunistic routing protocols have been proposed for mobile ad hoc networks. The packet delivery rate of most of these protocols decreases with increased mobility in the network. In this research paper we propose a method Optimal Data Delivery Routing (ODDR) that uses the help of intermediate nodes as back up nodes in data forwarding to achieve approximate 100% data delivery in highly mobile ad hoc networks. Simulation results show that our method achieves the highest data delivery compared to the latest opportunistic protocols in highly dynamic
