%X Reliability is crucial in many wireless sensor network(WSN)applications.Most of existing approaches are redundancy-based,such as employing multi-path or retransmission schemes.However,those designs often waste energy,and thus shorten the network lifetime.To address this issue,this paper proposes an energy aware method which employs network coding scheme based on multi-path routings.By encoding a group of data into independent new packets and transmitting them along multiple paths,this paper offsets the effect of link failure with a little extra overhead.The other strength of this design is that it only needs small-scale linear operations.An approximate method to effectively estimate the number of paths needed is also employed.Comprehensive simulations and results verify the validation of the theoretical results in the paper.
