Multicast Capacity-Delay Tradeoff with Network Coding in MANETs

We consider an Ad-hoc network operating in multicast transmission mode in this work. To achieve a better transmission performance, especially in network capacity, transmission delay and their tradeoff, we propose to apply network coding and infrastructure mode respectively in two network models. In the model applying network coding, we introduce two-hop relaying algorithms with and without destination cooperation, and multihop relaying without cooperation. The capacity and delay also have an order improvement individually comparing to networks without base stations. At last, we propose a network model combining network coding and infrastructure mode. In such network, we obtain the results of capacity and delay and the order improvements on both of them and their tradeoff are illustrated as well. Therefore, we give a complete comparison of all the network models and algorithms in the end.
