基于小世界模型的传感器网络节能查询策略

查询处理是传感器网络中最重要的技术之一。以降低查询能耗为目的，提出了一种基于小世界模型的查询策略（CardSN）。该策略以关联作为长程连接，降低了网络平均路径距离；将各节点的邻居相对定位，使查询处理获得了方向性。仿真实验结果表明：CardSN具有良好的可扩展性，且能耗明显低于ZRP和CAPTURE。

Small-world-based energy-efficient query strategy for sensor networks

Query processing is one of the most important technologies in sensor networks. To reduce energy consumption of query, a small world based query strategy named Contact-Assisted poweR-efficient Direction-sense-achieved query strategy for Sensor Networks (CardSN) was presented. In CardSN, Contacts act as shortcuts to bring down the average path length of the network; a distributed relative localization algorithm was introduced to achieve a sense of direction. Experimental results show that CardSN has good scal...
