| 中文摘要: |
| 无线传感反应网络通过引入具有资源丰富且可移动的反应节点，极大地增强了现有的无线传感器网络的应用范围.本文针对距离反应节点越近传感节点能量消耗越快的问题，研究了基于容量约束的最大跳数最小化的问题，并在此基础上提出了一种分布式近似算法.仿真实验表明，该算法在不需要全局信息的情况下，通过设置节点的容量约束，限制节点每轮转发某个事件的最大报文数，以降低单个节点的最大能耗，达到延长网络生存时间的目的. |

| Wireless sensor and actor networks greatly enhances the scope of the wireless sensor networks’ applications by introducing powerful and even mobile actors. In this paper, the problem based on the capacity-bounded and min-max hops is discussed and then a distributed approximate algorithm is also given. Simulations show that the algorithm can limit the number of the retransmiting packets greatly for some event, and reduce the maximal energy consumption of single sensor, and prolong the network lifetime by setting the capacity constraint of the sensors without the global information. |
