摘要：In this paper, we propose a Link-Utility-Based Improved Backoff Cooperative MAC Protocol for MANET with fair scheduling algorithm. In this fair scheduling algorithm, a priority queue is used to fairly allocate the resources. The priority queue consists of number of slots allocated for each flow, optimal transmission rate of flow and optimal transmission power of flow. We implement the new improved link-utility function that uses the optimal transmission rate and optimal transmission power.After getting the input priority queue, the fair scheduling algorithm is applied. This fair scheduling algorithm thus fairly allocates the resources to the nodes. Simulation results show that the proposed algorithm improves the throughput and fairness of the flows.
