【摘要】 社会网络中节点的移动特点可以归结为强移动性和弱移动性两种类型。提出的MTBR(Mobile-Tendency Based Routing)算法引入了移动倾向的概念,将人的移动习惯与节点的移动规律进行关联。该算法通过检测出社会网络中强移动性节点的移动倾向,并利用强移动节点来携带数据并进行数据转发。实验数据表明,节点移动性越强其移动倾向越明显;相较于同类算法,MTBR算法可以有效地将消息向较远的目的地转发,其产生的转发能耗较低,送达率更稳定。更多还原

【Abstract】 The nodes in the social network can be classified into two types as strong mobility and weak mobility.The MTBR(Mobile-Tendency Based Routing)algorithm was proposed.And MTBR introduces the concept of‘Movement Tendency’which associates the human movements with their behavior habits.The algorithm detects the movement tendencies of the strong mobility nodes and takes advantage of strong mobility nodes to forward the messages.The simulation results indicate that the movement tendency will be more apparent with a stronger mobility.Besides,compared with other algorithms,MTBR algorithm can effectively forward the messages to the ulterior area near the destination,and produce fewer message copies and achieve a higher delivery ratio.更多还原
