如何充分利用各种资源作为移动代理节点实现信息有效交付和网络服务，是机会网络研究中的关键问题。以此为研究背景，针对现有的传输限制，及现有算法对真实网络的适应性等问题，结合节点社会属性，提出一种基于节点意愿度的机会网络中的消息传输机制WDMT。算法充分考虑相似性，节点活跃度，社团温度及朋友影响等社会因素，合理地选择移动代理。真实数据集上的实验结果表明，与现有算法相比，WDMT能够在保证消息交付成功率的同时，降低网络开销及端到端的传输时延。

It is a key issue in opportunistic networks that how to make the best use of resources as a mobile agents for effective delivery of informa-tion and networking services. Takes it as a background, and regards of the problem of the existing transfer limit and the adaptation of tra-ditional algorithms to real-world network, proposes a message transmission mechanism based on willingness degree of node in opportunis-tic network,WDMT, which combined with nodal social attributes. In order to select mobile agents reasonably, WDMT gives full consider-ation to the society-related factors, including similarity, node activeness, community temperature, friends' influence and so on. The exper-imental results of real-world datasets show that compared with the traditional algorithms, WDMT can improve the success rate of data de-livery, as well as reduce the network cost and end-to-end transmission delay.
