中文摘要： 随着智能手机等移动设备的普及与移动应用环境的逐渐成熟，利用人们携带的移动设备形成机会网络为用户提供资源的共享和服务的协同成为机会网络的主要应用。由于节点资源的自主贡献特点，节点的有效协作成为应用实现的基础。本项目基于社会网络理论建立描述机会网络节点之间的依赖关系及其动态特性模型，并建立合理的模型评价方法；考虑机会网络自主贡献特点，研究自私节点对网络性能的影响，进而提出机会网络节点协同机制；研究节点信任模型；设计出高效、可靠转发算法；研究机会网络高效编码感知组播路由度量机制，并设计高效机会组播路由算法。本项目的研究成果对机会网络的应用和发展具有重要的学术意义和应用价值。由于特殊的地理环境和社会环境，在新疆地区开展机会网络研究有着非常广阔的应用前景和特殊意义。

英文摘要： With the popularity of mobile devices such as intelligent phones and the gradual maturity of the mobile application environment, forming opportunistic networks by using the mobile devices people carry to provide users with resource sharing and service collaboration is the main application of opportunistic networks. The implementation of this application is based on the effective cooperation of the nodes, due to nodes contribute their resources automatically. The project introduces the dependency relationship between nodes in opportunistic networks and its dynamic characteristics model based on the theory of social network, besides establishes a reasonable method to evaluate this model. Taking into account the independent contribution characteristic of opportunistic networks, we research how selfish nodes influence the performance of the network, then put forward the node cooperation mechanism of opportunistic networks, and research the trust model of node ,and design the efficient and reliable forwarding algorithm. We research the efficient coding-aware multicast routing metric mechanism of opportunistic networks, and design efficient opportunistic multicast routing algorithm。Our findings will have great academic significance and value on application and development of opportunistic networks. Due to special geog
