Leaky Bucket Algorithm for Congestion Control

Increasing demands on a network with an excessive downloads will saturate its capacity. There are different congestion control mechanisms which helps a network to operate in an optimal region of low delay with high throughput and thereby preventing the network from becoming congested. In this paper, the leaky bucket algorithm is used to control transmission rate in a network. It can be used to check data transmissions, in the form of packets to define limits on bandwidth. By setting the bucket size and output flow rate, the code can be refined to slow, medium and fast. Leaky bucket program is transmitted to Arduino board and from there to another computer. The results obtained are found to be similar. Arduino is a programmable logic controller and the experimented result shows the efficiency of the proposed method by greatly reducing the congestion in the network.
