Novel data transmission method in wireless sensor network using network coding
Jianbo Xu · Computer Engineering and Applications Journal · 2013
Recent researches show network coding can improve data transmission reliability in wireless sensor networks,existing network coding-based data transmission strategies select encoding vectors randomly and use fixed paths to transmit packets,which causes performance deficiencies.This paper designs a new scheme for constructing encoding matrix,and proposes a novel reliable data transmission method.Any k encoding vectors of the new encoding matrix are linearly independent and encoding vectors are not need to be transmitted to sink.Data forwarding usesregion pushingmechanism,which automatically selects the best forwarding nodes topushpackets from one area to another area closer to sink.Analysis and simulation results illustrate that the new proposed method can improve data transmission reliability and reduce network energy consumption.
