Congestion adaptive routing in wireless mesh networks
(2010) Tiwari, A.K.; Basavaraju, T.G.; Chandavarkar, B.R.
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. Â©2010 IEEE.
