Qingxu Xiong · Chuangan jishu xuebao · 2012
Based on the concept of semantic communication,a novel application-oriented task composition algorithm is proposed for Wireless Sensor Networks(WSNs).A united WSN MAC framework is discussed by involving the algorithm with WSN MAC protocols.The prototype by introducing the framework to IEEE 802.11 MAC and S-MAC are investigated respectively.Simulation results demonstrate that the improved MAC protocols could effectively decrease the average energy consumption and time delay,especially for a WSN sensing multi-kind of information.
