Source Rate Control for opportunistic Routing

Due to the popularity of wireless networks, opportunistic routing emerges and improves performance by utilizing the broadcast nature of wireless communication. However, without controlling source rate, capacity of bottleneck could be consumed by its neighbors and that leads to lower throughput. This work showed how source rate impacts the performance of opportunistic routing and proposed a source rate-based congestion control at layer 2 for better throughput. Simulation results showed that throughput is improved by about 35% with source rate control and fewer resources consumed.
