Network coding-aware routing in multi-hop CSMA wireless networks
摘要
Abstract
To improve the performance of multi-hop CSMA( carrier sensing multiple access) wire-less networks, a network coding-aware routing scheme, JOCR( joint optimization coding-aware rou-ting),was proposed.First, based on the ICN(ideal CSNA network) model, a minimum time cost model (MTCM) based on the joint optimization of the routing layer and the MAC(medium access control) layer was constructed by introducing the network coding-aware routing.In the MTCM, the interactions among the coding opportunities, the flow assignment and the performance of the MAC layer in CSMA wireless networks are balanced.Then, the SQP( sequence quadratic program) meth-od was used to obtain the optimal flow assignment scheme on the routing layer, the network-coding scheme and the parameter setting scheme of the CSMA protocol on the MAC layer, making sure that the network system can accomplish all given data delivery tasks with the minimum time cost.The simulation results show that compared with the existing schemes, the JOCR scheme can reduce at least 10%time cost.Network coding-aware routing and the joint optimization of the routing layer and the MAC layer can reduce the minimum time cost and improve the performance of multi-hop CSMA wireless networks.关键词
