摘要
En 中文
In intermittent connectivity wireless networks, packets are always transmitted to their destinations through the cooperation of intermediate nodes, and the limited network resources can be effectively utilized through network coding approaches. However, a large amount of resources will be consumed while all the nodes act as coding nodes simultaneously; meanwhile, redundant coded packets are injected into the network. Therefore, to determine the number of coding nodes and restrain the diffusion of coded packets, a new dynamic coding control mechanism is proposed. In this mechanism, coding nodes are scheduled in a distributedmanner based on the network community scale. Moreover, the coding opportunities and forwarding priorities of packets are determined according to the packet redundancy. Simulation results show that the connection opportunities can be exploited, and the utilization of network resources can be optimized.
