Review on Cross-Layer MAC Protocol of Heterogeneous Wireless Sensor Networks
Fei Gao · Journal of Yunnan University of Nationalities · 2011
In heterogeneous wireless sensor networks(HWSN),nodes,links and protocol are all heterogeneity,which has aroused much attention to the research on media access control protocol(MAC Protocol) of HWSN.In order to improve the overall network performance,the relevant theory and methodology for the cross-layer design emerged.But the research of cross-layer MAC protocol for HWSN is just at the initial stage and the practical application of cross-layer MAC protocol for HWSN is still immature.In this paper,the current cross-layer MAC protocol of HWSN was summarized,classified and compared,and the typical protocol selected from the channel access strategy and related layers were analyzed in detail.Moreover,the possible development and existing problems of the cross-layer MAC protocol design were discussed to provide reference for future research.
