针对现有水声传感网络中的地理位置路由协议的高延时等特点,提出低时延的ABGR协议.该协议基于节点的位置信息,在最大的传输半径内,根据候选转发节点在源节点和目的节点上的投影值大小,以最小的时延将数据包传送到目的节点.仿真结果表明,与选取比较的协议相比,ABGR协议在平均端到端时延最少减少1.8%.数据包传送率提高大约2.3%以上.
The existing protocols of geographic routing protocols have high transmission delay, the low delay of ABGR is proposed. This protocol based on the location of nodes, in the maximum transmission radius, according to the candidate forwarding node on the source node and destination node size of the projection value, with the minimum delay to send the packet to the destination node. The result of the simulation shows that the ABGR protocol reduce transmission delay at least 1.8% and improve the packet delivery ratio about 2. 3% compare with other two protocols.
