Abstract :
A novel application-specified MAC cross-layer design approach is proposed for wireless sensor networks. By using SWE architecture and Sensor ML, the sensor ontology is constructed, and the special inference ruler for MAC is defined by adopting computation geometry algorithms. By integrating application semantics with 802.11 and SMAC protocol, we propose the novel MAC protocols. The redundancy among data is reduced by the negotiation before transmission. Qualitative analysis and simulation results show that the proposed MAC protocols could reduce more than 20% energy consumption than the original ones.
