面向服务的架构在系统集成中所展现的诸多优点使其成为未来军事信息系统建设的重要参考。在构建基于SOA的战术通信网络中，如何完成通信资源服务化和通信应用的融合是较为重要环节，服务化的网络资源的发现是其实现的前提。战术通信网络服务化的实现，有助于通信系统和服务即插即用、按需信息共享、协同作战指挥和柔性重组抗毁。结合战术通信网络自身的特点，参考传统服务发现实现策略的基础上，给出了一种基于位置信息的服务发现协议算法，将路由协议算法引入到服务发现机制中，来有效地提高服务发现效率。%SOA ( Service-Oriented Architecture) presents many advantages in systems integration,thus be-coming an important reference for construction of future military IT system. How to realize the service of communication resources and the integration of communication applications now becomes a key link in the process of constructing SOA-based tactical communication networks, and the discovery of service-oriented network resources also essential precondition for this implementation. The realization of service-oriented tactical communication network could contribute to ‘plug and play' for communication systems and serv-ices,‘on demand' information sharing,cooperative operation command and flexible reconstruction and survivability. In considering the characteristics of tactical communication network itself,and with reference to traditional service discovery and implementation strategy,a position-based service discovery protocol al-gorithm is proposed. And the routing protocol algorithm is introduced into the service discovery mecha-nisms,thus effectively improving service discovery efficiency.
