摘　　要：传感网络多路径传输中的不同路径带宽不同,为实现最优的传感网络负载均衡,需要对其传输数据合理分配。提出针对无线多媒体传感网络的多路径可靠传输数据分配方法。通过计算无线多媒体传感网络感知范围内节点部署数量的上限与下限,对感知范围内的节点展开部署,获取最佳节点部署结构。对无线多媒体传感器网络中SCTP耦联内的全部数据传输路径展开延迟判断,并根据延迟判断结果选择传输路径。基于负载均衡情况进行可靠数据分配,保障网络数据平稳传输。仿真结果表明:所提方法迭代100次时即可完成收敛,此时数据传输速率约为4 000 bps;流量均衡度高于75.6%;运行至80 s左右时实际队列长度已被平稳控制在35左右。实现了无线多媒体传感网络多路径高效传输,避免拥塞情况发生。The bandwidth of different paths in multipath transmission of sensor networks is different.To achieve optimal load balancing of the sensor network,it is necessary to allocate the transmitted data reasonably.A data allocation method for reliable multi-path trans-mission in wireless multimedia sensor networks is proposed.By calculating the upper and lower limits of the number of nodes deployed within the sensing range of a wireless multimedia sensor network,the deployment of nodes within the sensing range is carried out to ob-tain the optimal node deployment structure.Delay judgment is performed on all data transmission paths within the SCTP coupling in wireless multimedia sensor networks,and transmission paths are selected based on the delay judgment results.Reliable data allocation based on load balancing ensures smooth transmission of network data.The simulation results show that the proposed method can achieve convergence after 100 iterations,with a data transmission rate of approximately 4000 bps.The traffic balance is higher than 75.6%.When running for about 80 seconds,the actual queue length has been steadily controlled at around 35.Efficient multi-path transmission in wireless multimedia sensor networks is implemented,avoiding congesting while achieving efficient multi-path transmission.
