摘要
在用户群体之间高效传输信息是组建无线自组网的基本目标之一。对无线自组网中的信息传输问题进行了阐述和分析,说明了现有的机制及其面临的问题。针对3种信息传播模型,在不同的网络场景下模拟了无线自组网中节点之间的信息传输情况,包括传染模型、信息连锁反应模型和多跳信息传播模型。模拟结果表明,无线自组网的信息传输能力与信息传播模型、信息的流行性和节点运动模型密切相关。
Effective information share and transmission among users is one of primary objects in constructing wireless sell-organizing network （WSON）. Issues on information transmission in WSON were expounded and analyzed at first. Available schemes and existent problems were outlined. Information transmission among mobile nodes in WSON was simulated in various experiment scenarios in detail under the three kinds of models, including infection model, information chain-reacting model and multi-hop information transmission model. Simulation results show that information transmission capability is dependent on information transmission models, popularity of information and mobility models o[ nodes.
