摘要: 无线传感器网络中节点的能源和处理能力受限,难以提供大规模的、以数据为中心的服务。为了解决以上问题,提出了一个基于虚拟位置的环路由协议。此协议使用分布式哈希表管理数据。虚拟位置概念的引入减少了冗余的路由信息并优化了路由的路径,从而减轻了节点的负担并提升了数据传送的效率。根据仿真结果以及与相关协议的对比,证明了此协议的有效性和可扩展性。

Abstract: A virtual position-based ring routing protocol was presented. This protocol can serve as the infrastructure of a large-scale and data-oriented service in wireless sensor network. This protocol used distributed Hash table to manage data. The idea of using virtual position lead to the benefit that less redundant routing information was generated, and thus the routing paths were optimized. This benefit also reduced nodes’ working load and improve data transmission efficiency. Detailed simulation and comparison with relative protocol show that this protocol achieves good efficiency and scalability.
