| 摘 要： | 随着无线网络技术的发展，无线网络中对数据传输应用的需求也越来越多。文中结合对无线自组织网络特点的分析，提出了无线自组织网络中一种基于社区划分的数据转发方法。首先将无线自组织网络中的节点按照兴趣度划分为多个社区，再根据数据传输的区间划分选择不同的消息分发机制，社区内节点的数据转发通过限制跳数的传染病算法实现，节点间的数据转发跨跃社区时采取由中继节点携带转发的消息分发策略。仿真实验结果证明本算法实现了无线自组织网络中时间和空间效率的平衡。

| Abstract: | Along with the development of wireless network techniques, the requirements of data transmission application in wireless net- works become more and more. According to the characteristics of the wireless Ad Hoc network, propose a data forwarding method based on community division. Firstly, it divides nodes into different communities by interest degree, and then selects different data distribution algorithm according to the data transmission range, in community nodes using hop-limited epidemic algorithm to realize data transmis- sion, and using carry-forward strategy by relay nodes when data needs to sent to other community. The algorithm realized the balance between space and time efficiency in the wireless self-organization network. |
