摘要 链路层协议的设计是水声网络的关键技术之一。它通过控制数据收发,实现网络数据包的可靠、有效传输,进而为网络层提供服务。针对水声通信系统低速率、高延时和低可靠性等特点,利用网络仿真软件OPNET对采用ALOHA协议和MACAW协议的网络进行了完整建模,给出了对等式网络和主从式网络下两种协议在吞吐量、丢包率、平均时延和能耗四个方面的仿真结果。通过对仿真结果的分析,为实用协议的设计提供了有效的参考数据和策略。 The protocol designing of MAC layer is one of the key techniques for underwater acoustic network. It controls sending and receiving of data frame, and makes the transmission of data frame work reliably and effectively, then provides a service for the net-layer. In underwater acoustic communication system which is characteristic of low speed, long delay and fallibility, the whole modeling for the network that adopts protocol of ALOHA and MACAW was given using OPNET, which is one kind of software for network simulation. In the network topology of identity and Master-slave, performances of improved ALOHA and MACAW protocols were compared on these aspects throughput, delay, rate of data drop, and power efficiency. After analysis of these, necessary reference data and strategy for protocol designing were proposed.
