| 摘 要： | 为保证WSN的服务质量(QoS),需精确求解其性能上界。对进入WSN节点的数据流进行漏桶管制,节点为数据流提供基于速率-延迟模型的服务保障,在已有簇状拓扑WSN性能模型研究基础上,利用确定性网络演算理论推导簇树WSN节点的有效带宽、缓冲区队列长度上界和数据流端到端延迟上界。

| Abstract: | In order to guarantee the Quality of Service(QoS)of Wireless Sensor Network(WSN),the QoS deterministic upper bounds need to be accurately calculated.The data flow entering the node is regulated by leaky bucket,and the node provides rate-latency service for the flow.The node’s bandwidth requirements,queue length upper bound of buffer and the end-to-end upper delay bound have been derived for cluster-tree WSN based on the existing cluster-based WSN performance model using deterministic network calculus theory. |
