一种用于水声通信网的全动态TDMA协议
A fully dynamic TDMA protocol for underwater acoustic networks
摘要
Abstract
In order to solve the contradiction between communication efficiency and energy saving in underwater acoustic sensor network under certain applications, a fully dynamic scheduling TDMA (time division multiple access) scheme aimed at the specific network topology is proposed, which is called FD-TDMA(fully dynamic TDMA). It employs a dynamic round-trip scheduling method, a hybrid ACK( acknowledgement) strategy and the conservative sleeping mechanism. According to the local and neighboring nodes' sending and receiving situation and the known topology information, each node in the network dynamically and real-timely updates its stay durations in the receiving, sleeping and waiting states, and enters its transmission slot at the right time. Simulation in OPNET platform shows that FD-TDMA can achieve significantly higher communication efficiency and energy utility than the fixed-slot TDMA with the fixed sleeping mechanism and hybrid ACK mode. In addition, the FD-TDMA protocol is of stable performance and adequate for different traffic loads and network sizes.关键词
