摘 要: 通过对社交关系的分类及对信息可利用性进行分析,提出一种基于计算信息可利用值的策略,通过设定门限值拓展信息传递路径并控制结点信息传递的泛洪现象。仿真实验结果表明,该机制与经典算法相比降低了路由开销,在性能方面有明显提升。
关 键 词: 计算机应用;机会网络;信息可利用性;门限值;路由开销;社会关系

Abstract: Through the classification of social relations and the analysis of the available information, a strategy based on the calculation of information usability is proposed to expand the information transmission path and control the information transport of the nodes by setting the threshold value. Simulation experiment results show that the routing overhead is reduced compared with the classical algorithm, which has significantly improved in performance.
Key words: computer applications; opportunistic network; information availability; threshold value; routing overhead; social relations
