| 摘 要： | 研究了光无线混合接入网中具有抗毁能力的节能路由问题,结合光网络单元(ONU)休眠控制和风险备用路由表维护机制,提出一种有效的可靠绿色路由算法。该算法为每个无线路由器维护一个风险表,以记录网络中路径是否可用以及ONU活跃与否的状态信息,通过鼓励选择ONU活跃的可用路径来传输数据,可降低全网丢包率和能耗。仿真结果表明:该算法能够在稳定丢包率的同时更好地节省能量。

| Abstract: | Survivable routing with a consideration of energy-efficiency for a hybrid optical-wireless broadband access network has been investigated in this paper.Combined with a sleep control mechanism of Optical Network Units(ONU) and a risk-alternate routing table,a green routing algorithm,called Risk and Energy Aware Routing(REAR),has been proposed.REAR maintains a risk table in each router to record the statuses of available paths(live or stale) and ONUs(active or sleep),and encourages to route packets along a path with active ONUs,which is beneficial to further reduce packet loss and energy consumption.Simulation results show that REAR has a stable packet loss performance and a better energy saving. |
