| 摘 要： | 针对盲目广播带来的广播风暴问题,提出了一种适用于Ad Hoc网络的跨层模糊逻辑广播算法(cross-layer fuzzy logic broadcasting algorithm,CLFBA).该算法应用跨层设计的方法,在保持原有介质访问控制层(medium access control,MAC)和路由层严格分离的基础上,允许路由层共享MAC的接收信号强度信息.采用模糊控制获得节点重播分组的概率,赋予增加通信面积大的节点和剩余能量高的节点较高的转发概率.CLFBA减少了广播过程中产生的冗余、竞争和冲突,均衡了网络中节点的能量消耗.仿真结果表明,与路由层应用泛洪和概率泛洪算法、MAC层应用IEEE802.11协议相比,CLFBA提高了转播节省率,延长了网络生命周期,降低了平均节点丢包率和平均端对端延迟.

| Abstract: | To solve the broadcast storm problem caused by blind flooding,a cross-layer fuzzy logic broadcasting algorithm for mobile ad hoc networks(CLFBA) is proposed.CLFBA allow the routing layer to share the received signal power of the MAC layer by the cross-layer design while still maintaining separation between the two layers.The rebroadcast probability is calculated with fuzzy logic,by which the nodes with more additional transmission range and residual energy have higher probability to rebroadcast the packets.... |
