Taxonomy and evaluations of low-power listening protocols for machine-to-machine networks

Even though a lot of research has made significant contributions to advances in sensor networks,sensor network protocols,which have different characteristics according to the target application,might confuse machine-to-machine (m2m) network designers when they choose the protocol most suitable for their specific applications. therefore,this paper provides a well-defined taxonomy of low-power listening protocols by examining in detail the existing low-power sensor network protocols and evaluation results. it will also be very useful for helping m2m designers understand specific features of low-power media access control protocols as they design new m2m networks. © 2014 kwang-il hwang and sung-hyun yoon.
