水下传感器网络采用声波进行通信,具有长时延、低带宽、高错误率、低能耗要求和稀疏部署等技术挑战,使现有通信协议无法满足性能要求,节点的有限资源决定了其上运行的协议栈不能太复杂.文章阐述了水下传感网络的应用、通信特点,分析了传统协议架构在水下传感网络的局限性,指出:水下传感器网络需要研究一种新型的、绿色网络体系架构模型,基于该架构模型实现各层协议的优化设计,在满足QoS性能要求和系统有限资源的约束下,提高能量效率、延长网络生存期,实现绿色网络.

Underwater sensor network (UWSN) adopts acoustic communication,characterized by high delay,low bandwidth,high error rate,low energy-consumption requirement and sparse deployment which lead to great challenges for UWSN communication.Conventional communication protocols are unable to satisfy the performance of UWSN while the limited resources of nodes determine the protocol stack run-ning on it shouldn't be much complicated.Through analyzing the characteristics of application and commu-nication in UWSN and the limitations of traditional protocol architecture for UWSN,we indicate that re-search of UWSN for intelligent environment monitoring require to develop a new,green network protocol architecture model,and realize protocol optimization design for each layer in the new protocol architecture model so as to improve energy efficiency,prolong the network lifetime and achieve green network while meeting the requirement of QoS with the constraints of limited resource.
