一种自适应无线移动自组织网络数据传输方法

An adaptive data dissemination approach of wireless mobile ad hoc network

网络节点密度是无线移动自组网选择数据传输协议时需要考虑的一个重要因素.为了在网络密度动态变化的情况下保证网络的传输效率,提出了一种基于启发式信息的自适应数据传输策略,即在稀疏不连通网络条件下,节点选择传染病数据传输模式,而在密集连通条件下,节点选择AODV数据传输模式,以优化系统性能.仿真结果表明,这种启发式的传输策略可以更好地适应网络密度的变化.

Network density was an vital factor which needs to be considered when choosing data dissemination protocol in mobile ad hoc networks.To ensure the efficiency while the network density changing dynamically,an adaptive data dissemination strategy was proposed based on heuristic information,thus under the sparse network conditions,epidemic routing was selected for the data dissemination strategy and in the densely-connected conditions,AODV protocol was chosen as the data dissemination strategy to optimize the performance of system.The heuristic strategy is proved to be effective by simulation results while the network density changing dynamically.
