无线传感器网络中基于多向量的拥塞控制

由于无线传感器网络结点分发信息非常方便，因此它在军事和智能居家领域有着广泛的应用前景。如何在这些网络中建立公平、高效、节能的传轮机制将数据汇集到基站是该网络中的一个重要问题。本文提出了一种分布式动态的对不同的路由路径建立多向量信号控制的算法。该算法同时考虑了不同结点的流量，子结点的数目以及子结点的层数等，并将信息快速反馈到检测到的拥塞中，从而迅速缓解拥塞。模拟实验结果和分析表明该机制具有公平性、有效性、稳定性和节能性。

Multivectors-based Scheme for Congestion Control in Wireless Sensor Networks

Wireless sensor networks have wide applications fields such as military and intelligent home management due to ease deployment of these sensor nodes. It is important to build an efficient, fair, power-efficient transport scheme to gather the message and send message to the sink or base-station. This paper proposes a distributed, dynamic, based-on route path multi-vector control mechanism. It can quickly detect congestion, and send the feedback signal to the downstream node. The scheme includes the traffic of different nodes, the total number of sub-nodes and the levels of the sub-tree. Simulation results show that the proposed management scheme can achieve a good level of fairness, power-efficient and stability.
