Congestion adaptive routing in Wireless Mesh Networks
Ashish Kumar Tiwari, T. G. Basavaraju, B. R. Chandavarkar · 2010
The main reason for packet loss in Wireless Mesh Networks (WMNs) is due to congestion. Presently, routing in WMNs is not congestion-adaptive. Routing may let a congestion happen which is detected by congestion control. The way in which the congestion is handled results in longer delay and more packet loss and requires significant overhead if a new route is needed. Hence, we propose a congestion adaptive routing protocol (CARP) for WMNs with such properties. Our ns-2 simulation results confirm that CARP can successfully achieve a high packet delivery ratio with lower routing overhead and latency in WMNs.
