Book Description
ABSTRACT: To improve the performance for wireless networks, we implemented a congestion-aware cross-layer design in NS-2. The MAC layer adaptively selects a transmission data rate based on the channel signal strength information from physical layer and congestion information from network layer. The MAC layer utilization gathered at MAC layer is sent to DSR as a congestion aware routing metric for optimal route discovery. We modified the source codes of 802.11 MAC layer and DSR protocol. The simulations show that rate adaptation in MAC layer improves the network performance in terms of throughput, delivery ratio, and end-to-end delay; using congestion information from MAC layer in routing discovery improves the performance of the network benefited from overall network load balance.
