| 摘 要： | 基于水声通信网的特殊的组网形式,它的MAC层协议的设计目标不同于传统的陆地无线网,节约能量是其首要考虑的问题。在目前现有的MAC协议中,802.11的DCF机制是基于竞争类的代表;而S-MAC协议则综合了固定分配类和随机竞争类的优点并以节能和可扩展性为主要设计目标。本文通过NS仿真对水声通信网应用这两种协议的性能进行了分析比较。

| Abstract: | Because of the special network form of hydroacoustic communication network,its MAC layer protocol design goals are different from the traditional land-based wireless network.The primary consideration problem of hydroacoustic communication network is saving energy.In many current existing MAC protocols,DCF mechanism in IEEE802.11 protocol is the representative of MAC protocols on the basis of competition.While S-MAC protocol combines advantages of fixed allocation category and random competition category of MAC protocol, and its main design goals are energy efficiency and expansibility. This paper analyses and compares the performance of the two protocols in hydroaeoustic communication network by NS simulation. |
