A Review of Cluster-Based Congestion Control Protocols in Wireless Mesh Networks
Source: Universiti Teknologi Malaysia
Packet loss in Wireless Mesh Networks (WMNs) is due to congestion and probably due to high bit error rate caused by interference, link and node failures. Presently, congestion control and routing protocols in WMNs are not seen to have tamed this recurrent problem of congestion being experience most times in the wireless network. Routing techniques may lead to a congestive scenario and the congestion control should detect and probably avoid such situations. The way in which the congestion is handled may results in longer delay and more packet loss and a very significant overhead may also be incurred.
