摘要
随着Ad hoc网络规模和应用范围的不断扩大,网络需要提供的服务数量和种类愈来愈多。同时,又由于处在动态环境中,提供服务的节点可在任意时刻进入或离开网络。有效而及时地进行服务发现,成为移动Ad hoc网络面临的一项新任务,也是网络具有可用性的重要特征。本文综述了近年来国内外在该领域的研究成果,对已有的移动Ad hoc网络服务发现协议进行了分类,并对它们做了较全面的分析总结和深入的比较,最后指明了进一步的研究方向。
With the enlargement of the network scale and application scope of mobile Ad hoe networks, the kinds and amount of service needed by such networks become more and more. Furthermore, in this dynamic environment, different nodes offering different services may enter and leave the network at any time. Efficient and timely service discovery becomes a new task of mobile Ad hoe network. Discovery of services is a crucial feature for the usability of mobile Ad hoc networks. In this paper, we survey the researches of recent years on service discovery, classify the existing service discovery protocols of mobile Ad hoc networks. Moreover, we summarize and compare these protocols. Based on the analysis, further research issues that still need investigation are listed.
