Introduction

There is a huge increase in the number of wireless networks and all of them demand a high bandwidth and QoS specifications. In the wired network, these things are taken care by admission control and several other policies. But in wireless environment this is becoming more and more difficult. To know these things better, we must be familiar with some key terms.

—Weighted round robin algorithm visits each queue and sends a number of packets depending on the weight allotted to the queue.

—DRR algorithm does use the Deficit counter value for transmitting the packets but it updates the DC value just by subtracting the size of the packet directly.

— By using the penalty factor, we are actually penalizing the flows that are not utilizing the network resources in a proper way
