摘　　要：蓝牙Mesh网络使用泛洪进行多跳通信,在没有路由机制的情况下,由于消息的连续广播,原有泛洪机制会导致网络开销增大和通信延迟。本文基于能量有效的AODV改进算法E AODV使用MATLAB进行仿真,根据跳数、节点剩余能量、链路质量来选择最优节点进行数据包的转发。仿真结果表明,E-AODV算法可减小蓝牙Mesh网络中RREQ数据包传输数量,通过与传统泛洪、AODV算法比较,该算法能够有效降低数据包传输时延,降低网络能耗,提高网络性能。Bluetooth Mesh networks use flooding for multi-hop communication.Without the routing mechanism,the original flooding mechanism will increase the network overhead and communication delay due to the continuous broadcast of messages.In this paper,based on the improved energy efficient AODV algorithm E-AODV,MATLAB is used for simulation,and the optimal node is selected for packet forwarding according to hop count,node residual energy and link quality.The simulation results show that the E-AODV al-gorithm can reduce the number of RREQ packet transmission in Bluetooth Mesh network.Compared with traditional flooding and AODV algorithms,the algorithm can effectively reduce packet transmission delay,reduce network energy consumption,and improve net-work performance.
