无线传感器网络中基于定向扩散协议的跨层拥塞控制方法
Cross-Layer Congestion Control Approach Based on Directed Diffusion Routing Protocol in WSN
摘要
Abstract
According to the congestion problem of wireless sensor network, a cross-layer congestion control approach is developed based on the directed diffusion routing protocol. This approach includes local congestion control and global congestion control, which can feedback congestion by ACK and adjust sending rate by cross-layer notification. Simulation experiments show that the proposed approach effectively relieves congestion, reduces the energy consumption of the network and guarantees the packet transmission integrity. Compared to the CODA mechanism, the energy economizes 32.56% ,the fidelity increases for 6%.关键词
