摘要
海上高速率通信距离大,移动性要求高,传统的Ad hoc网络和802.11网络难以满足用户的数据通信需求,而Wi MAX网络具有传输速率大、支持自组织组网、覆盖范围广等特点,被认为是解决海上通信的希望。本文针对海上通信的特点和需求,提出一种基于Wi MAX网状网络的海上通信系统,设计一种"中心式"和"分布式"相结合的网络体系结构,并提出一种多信道带宽分配机制,实现长距离、多跳的船舶间和船岸间通信。并对提出的方法和机制进行仿真,验证了本文提出方案的可行性。
Communication distance and mobility is highly demanded in maritime high rate communication environment. And the traditional Ad hoc networks and 802. 11 data communication network is difficult to meet users' needs. WiMAX network with high transmission rate,supporting the self-organizing network,wide coverage,etc. It is considered to solve maritime communication of hope. In view of the characteristics and needs of the maritime traffic,this paper puts forward a kind of maritime communication system based on WiMAX mesh network,designs a kind of network architecture combines centralized and distributed mode,and puts forward a multi-channel bandwidth allocation mechanism,realizing the long distance,multi-hop communication between vessels and shore. At last,the simulation is put forward to verify the feasibility of the proposed scheme.
