(A hop-by-hop cross-layer congestion control mechanism is proposed. According to the congestion information obtained by checking the buffer occupancy rate and the congestion degree, on the basis of the open-loop hop-by-hop rate control of the transport layer, the node/node MAC layer channel is adaptively adjusted. Access priority enables nodes in a comprehensive sensor network to adjust the information sending rate according to partial congestion conditions. The NS2 simulation results show that the algorithm can effectively improve the network function and congestion control efficiency.)
