Opportunistic and Cooperative Forwarding in Mobile Ad-hoc Networks with Light-Weight Proactive Source Routing
Speaker(s) : Cheng Li, Memorial University, St. John's, CanadaMulti-hop wireless network has drawn a great deal of attention in the research community in recent years. Within the long period after it was proposed, the routing and forwarding operations in the multi-hop wireless network remain to be quite similar to those in the multi-hop wired network or the Internet, where the broadcast nature of the wireless medium is simply not utilized to enhance the data transmission ability in wireless network.
Opportunistic data forwarding through node cooperation opens a new paradigm for data forwarding in wireless networks. In our work, we propose a series of solutions to realize opportunistic data forwarding in mobile ad hoc networks (MANETs). Our solution is called Cooperative Opportunistic Routing in Mobile Ad-hoc Networks (CORMAN). CORMAN comprises three important components: (1) a new light-weight proactive source routing scheme PSR; (2) a large-scale live update scheme achieve quick routing information update with no extra communication overhead; (3) a small-scale retransmission scheme to further utilize the broadcast nature and to enhance the efficiency and robustness of the opportunistic data forwarding in MANETs. Significant performance enhancement has been achieved in terms of throughput, end-to-end delay, delay jitter, and communications overhead, when compared with other routing schemes such as OLSR, DSDV, AODV, and DSR.
