WiMAX is a highly reliable and cost effective technology. A Mobile Mesh Network (MMN) involves communication between mobile nodes and mesh routers. Based on the sponsor node to adjacent node Signal-to-Noise Power Ratio (SNDR) value of each node, the decision for inter-cluster or intra-cluster handover is made. TCP Round Trip Timer (RTT) method is used to reduce congestion in the Base Station (BS) during handover. The congestion at the BS is detected and the contention window size is dynamically computed based on the contention RTT in the MAC layer and congestion RTT in the transport layer.
