摘要：With the increasing number of spontaneously deployed Wi-Fi hotspots and community based networks, end users often experience performance degradation due to Starvation between the nodes in wireless mesh networks. The frequently occurred problem in wireless mesh networks is the starvation which occurred due to the nodes which are close to the gateway will always block the channel without giving a chance to the nodes which are far away from gateway to utilize the network bandwidth. So there is no scope for remaining nodes to access the channel. So to reduce starvation we propose an algorithm known Starvation Mitigation Algorithm (SMA) which states that, the gateway will work as an decision maker for the network and broadcasts the message to all the nodes when the network bandwidth is utilized by any single node. Then the node which is using the bandwidth will reduce its contention window so that remaining nodes will efficiently utilize the bandwidth and starvation will be reduced. The algorithm which we are proposing will mitigate the starvation in a network and bandwidth utilization is more compared to the existing algorithm and the drawback of decreasing throughput in existing system will be reduced and overall performance of the network will be increased
