Real-time Transmission Algorithm Based on Clustering in WSN

Using the cross-layer technology,this paper presents a real-time transmission algorithm based on clustering in Wireless Sensor Network(WSN).It identifies more than one optimal paths for each cluster head to the base station.It selects an optimal path from the paths with congestion control method.The data will be sent to the sink along this path.Simulation analysis shows that the algorithm provides real-time transmission and conducts congestion control effectively.
