| 摘 要： | 针对延迟容忍移动传感器网络提出一种基于广播的副本消除数据传输机制（CRD）.CRD机制中，传感器节点利用基站在频率f1上的大功率广播信息完成自身转发概率的计算和冗余消息副本的清理，基于转发概率在频率f2上完成节点间的消息转发.同时，CRD采用消息生存时间和消息转发域值M来完成消息队列的管理.仿真结果表明，与其他数据传输机制相比，CRD能达到传输成功率、传输延迟和通信开销的有效平衡.

| Abstract: | Proposed a broadcasting-based copy-removed data delivery scheme ( CRD) for delay tolerant mobile sensor networks ( DTMSN) . Using broadcasting information of base station on the frequency of f1 , sensor nodes not only can remove the redundant messages, but also can compute their own motion states and delivery probabilities which provide the basis for messages forwarding between sensor nodes on the frequency of f2 . At the same time, CRD employs the message survival time and message forwarding do-main M to manage the message queues. Simulation results show that CRD has a higher message delivery ratio and less data delivery delay than many other DTMSN data delivering approaches. |
