无线Mesh网中的Quorum节能机制

无线Mesh网络节能问题十分重要。文章讨论的基于Quorum的节能机制对网络规模、节点密度、移动性和多跳等因素不敏感，非常适合无线Mesh网络。Quorum节能机制主要基于MANET网络环境设计。Quorum系统根据时钟同步的难易程度，可以应用于同步和异步两种工作模式。目前对Quorum节能系统的研究主要集中在能量效率优化和自适应系统方面。对于异步和同步两种模式的协同，基于Quorum机制的节能与功率控制、MAC路由结合的跨层设计，是值得尝试的课题。

Quorum-Based Energy Conserving Mechanism in Wireless Mesh Networks

Energy conservation is a quite important issue for wireless Mesh networks. The Quorum energy conserving mechanism, discussed in this article, is quite suitable to wireless Mesh networks because it is insensitive to network scale, node density, mobility and multi-hop. Originally designed for the Mobile Ad Hoc Network (MANET) environment, the Quorum mechanism can work in two modes: synchronous and asynchronous, subject to the difficulty of clock synchronization. Currently, the research on Quorum energy conserving systems focuses on energy efficiency optimization and adaptive system. As to other issues, such as the collaboration between synchronous and asynchronous working modes, and the cross-layer design for integrating Quorum mechanism-based energy conservation with power control and Media Access Control (MAC) routing, there is much research to do.
