基于地理-机会的水下无线传感网的混合路由
A geographic-opportunistic hybrid routing for underwater wireless sensor networks
摘要
Abstract
The underwater wireless sensor networks(UWSNs)are known as the most perspective technology to monitor and explore the oceans. The challenge of acoustic channel characteristics for UWSNs data collection is put forward. The effective way to improve the UWSNs data acquisition efficiency is the fusion of the characteristics of the underwater acoustic communication with highly-dynamic network topology,and design of the high-performance routing protocol. Therefore a geographic and opportu-nistic hybrid routing(GOHR)for UWSNs is proposed. In which,the source node is used to calculate the candidate forwarding node set,and the normalized weighted value of each node in the set. The node in the set is sorted according to the normalized weighted value to form the forwarding node cluster. The expected weighted value of each cluster is calculated. The cluster node with the highest expected weighted value is selected as the forwarding node of the data package. In order to void the collision when the data package is forwarded for the cluster node,the timing-delay forwarding mechanism is set. The simulation results show that the GOHR protocol can improve the transfer rate of data package,and reduce the transmission delay of data package.关键词
