Study of network coding based on opportunistic routing in multimedia wireless mesh networks
Song Yun · Computer Engineering and Applications Journal · 2011
Making use of a deterministic network calculus tool,the wireless mesh network nodes'backlog upper bound,the end-to-end upper delay bound and the end-to-end upper delay jitter bound have been derived based on the existing link throughput model which is same with opportunistic routing.And then a Deterministic Network Coding(DNC) which meets the QoS is designed.An ETC(Expect Transmission Coding) considering the node's backlog upper bound is proposed to a guide line which determines the coding nodes.In order to improve the performance,the encode nodes using linear network coding before the node's backlog upper bound are exceeded.The represented ETP considering the jitter and the end-to-end upper delay jitter bound is a guide line which determines the received candidate nodes.Comprehensive simulations and results verify the validation of the theoretical results in the paper.
