水声传感器网络握手机制MAC协议研究

Research on Underwater Acoustic Sensor Networks MAC Protocol Based on Handshake Mechanisms

握手机制的MAC协议是水声传感器网络MAC协议的一个研究热点,针对水声信道高传播时延特性,分析了握手机制MAC协议在水声传感器网络中面临的三大问题:信道利用率低、控制包功能失效和接入信道不公平性。针对此类问题,提出了一些高效的解决方案,并阐述其优缺点,分析了现有的水声传感器网络握手机制MAC协议的后续研究方向。

Due to the non-negligible physical restrictions of the underwater acoustic communication,we summarize and analyze the three problems in the handshake protocol of UWASNs： low channel utilization,control packet function failure and access channel unfairness. Secondly, to solve the problems, this paper describes some efficient solutions, and analyzes their advantages and disad-vantages. Finally,we summarize the existing MAC protocols of UWASNs and put forward the follow-up research direction.
