| 摘 要： | 为满足大规模无线传感器网络局部区域信息收集时的QoS需求,在保证网络连通性的条件下最大限度降低网络能耗与控制开销,本文提出一种基于能耗均衡的按需QoS协议OQBED.该协议采用近似静态分簇和按需信息收集策略减少控制开销,通过有效选择工作节点数目以及执行簇头轮换机制来保障能耗均衡,并在簇头间选取满足QoS条件的最优能源路由来实现数据融合与传送.仿真结果表明,OQBED协议能有效减小控制开销,显著延长网络生命期,大幅度提高信息传输成功率. |

| Abstract: | In order to satisfy Quality of Service(QoS) demands of local field information collection,prolong network lifetime and minimize control overheads while insuring connectivity,an on demand QoS protocol for balance the energy dissipation(OQBED) is proposed in large-scale wireless sensor networks(LWSN).This protocol employs a novel near static clustering and on demand collection to reduce control overhead.It selects efficiently number of active sensors and cluster heads(CH) rotation mechanism to insure balance ... |
