一种容延迟移动传感器网络中的代码分发机制

容延迟移动传感器网络DT-MSN (Delay Tolerant Mobile Sensor Networks )是一种具有容延迟,非持续连接,数据传输率非对称和出错率高等特点的新型无线传感器网络.本文提出了一种在容延迟移动传感器网络中基于传染病模型的代码分发(Code Dissemination)机制,从而实现了在容延迟性网络环境下节点在线更新,并通过仿真对这种代码分发机制性能进行了分析.

A code dissemination scheme in delay-tolerant mobile sensor networks

DT-MSN(Delay Tolerant Mobile Sensor Networks) distinguishes itself from conventional wireless sensor networks by the following characteristics: intermittent connectivity, variable transmission delay, asymmetric data delivery rate, and high fault ratio. These characteristics make the reprogramming function in DT-MSN to be a challenge problem. This paper proposes a code dissemination scheme based on epidemic model to address this issue. The authors analyze the code dissemination scheme and optimize its performance. Finally, the authors simulate this data dissemination scheme to demonstrate the improved performance of this scheme.
