【摘要】Social selfishness of nodes is prevalent in delay tolerant network, which has negative impact on the efficiency and security of DTN performance. In recent years, since the first report of socially aware computing, more and more researchers Dropose to combine socially awareness, game theory and other methods with nodes' cooperation in DTN. Research on socially iware based cooperation mechanism in DTN becomes a hot issue both in academic and industrial communities. In this paper, we introduce the impact of socially selfish nodes on network performance. Moreover, we focus on the proposed cooperation mechanisms and categorized them into three kinds: game theory based, reputation based and virtual bank based. Each category is discussed in detail and the typical work is introduced. Especially, the features of these categories of cooperation mechanisms are analyzed and compared, which is helpful to both the academic researchers and DTN applications. Finally, future works about the socially aware based cooperation mechanisms in DTN are outlined.%针对节点的社会自私性(social selfishness)对容迟网络(delay tolerant network,DTN)中路由效率、网络性能和安全等造成的负面影响,采用社会感知(socially aware)、博弈论等方法
设计合理的协作机制是当前容迟网络研究的一个重要方向.文中首先描述了节点的社会自私性对容迟网络性能的影响.依据分析工具的差异,将已有容迟网络中基于社会感知的协作机制分为基于博弈论、基于信誉、基于虚拟银行3类.文中对各类协作机制的基本原理、方法和不足之处进行了分析和比较,最后对容迟网络中基于社会感知的协作机制的未来研究方向进行了展望. 【总页数】8页(120-127)
