中文摘要: 研究随机干扰影响下无线传感网络(WSN)的拥塞控制问题。本研究工作是将基于流模型的拥塞控制方法向WSN领域的拓广。由于WSN具有能量有限、突发事件流、可变拓扑和信道易受干扰等特殊性,使得对该问题的研究具有相当的复杂性和难度。 本项目针对WSN拥塞控制问题,采用动态建模和随机分析的方法,分析传输延迟、变拓扑和突发数据流等随机因素对WSN的影响、特征和动态性能,研究延迟约束、流量预测、兼顾能源有效性和公平性等情况下WSN的拥塞控制问题,给出网络系统随机稳定性条件,建立分布式拥塞控制机制。 本项目的实施不仅拓宽了WSN拥塞控制的研究领域,而且进一步丰富了网络拥塞控制的理论方法。因此,本课题的研究具有重要理论意义和实际意义。

英文摘要: In this project, we will deal with the problem of congestion control for wireless sensor works (WSN) subject to stochastic disturbances. This is an extension of congestion control based on fluid modelling to WSN. The characteristics of WSN, such as, limited power, suddenly burst large amount of information, variable topology, the interference of wireless links, for instance, will make this research more complex and difficult. The proposal will focus primarily on the modeling and synthesis of WSN congestion control. By means of stochastic theory, we will analyze the feature and dynamic performance of WSN under the influence of stochastic disturbances including transmission delay, variable topology, and bursty data flow. Under the conditions of signal delay, flow prediction, energy efficiency and fairness-aware, some distributed congestion control mechanism will be proposed, and various conditions of stochastic stability will be derived. The research outcome of this project will lead to a significant advancement of congestion control theory and will open up a wider and richer range of WSN application.
