随着人类海洋活动的不断增加,如何提供高性能、高性 价比、可靠安 全的海洋通信网络服务已成为一个亟待解决的问题。海洋是一个巨大的咸水体,其空间由岸基、水面、天空和水下组成,网络部署环境、气候条件和用户分布等与陆地空间存在较大差异,这导致陆基通信网络技术无法直应用到海洋环境中。卫星通信是目前仅有能提供海洋几乎全覆盖的通信网络技术,但是由于其制造和维护成本高、部署风险大,卫星服务的性价 比阻碍其被广泛应用,这也推动了近年来对海洋空间新型通信网络技术的研究和探讨。本书分析海洋通信网络所面临的环境特和技术发展所面临的挑战,介绍现有主要海洋通信网络技术,研究和讨论一些新型海洋通信网络的协议、算法和体系架构及发展趋势。   本书可为从事相关领域研究和发的人员提供有价值的借鉴,为高校师生了解海洋通信网络现状和发展方向提供指导,为政府部门和企事业单位的科研规划人员提供参考。
