Abstract—This paper proposes a network coding aware QoS (quality of service) routing (NCQR) for wireless sensor network, which exploits network coding technology to improve the QoS routing of wireless sensor network. Network coding condition with QoS constraint is proposed, which provides proof for coding opportunity detection. To facilitate the evaluation of discovered routes, a novel routing metric, called CQRM (coding aware QoS routing metric), is presented, which jointly considers link quality, node congestion and coding opportunity. Simulation results demonstrate that NCQR decreases the blocking ratio of QoS requests significantly and prolongs network lifetime.
