It is a challenge that using multipath transmit packets based on network coding in wireless mesh networks (WMNs). This paper proposes a mechanism that naturally adds network coding to multipath routing network systems. In the mechanism, network coding is compatible with improved multipath TCP (MPTCP). The destination feedback the degree of freedom of encoding block, and delays of packet delivery minimize reordering and timeouts. Using MPTCP, the source can send more encode packets and the transmission rate becomes more faster, and the multiple paths can achieve stability, and the network achieves higher throughput.
