A Quality of Service algorithm to reduce jitter in mobile networks

Abstract

The mobile networks are more vulnerable to ensure Quality of Service (QoS) due to the exponentially increasing number of users / devices, limited resources, etc. QoS is a set of service requirements to be met by the network. Jitter means the delay variation in transferring packets. There can be various factors that increases jitter. They are misbehaving nodes, unresponsive flows, issues in existing packet scheduling algorithms. In mobile communication system, a typical cell phone tower spreads radio signals ranges from 1 to 35 KM. The packets that come from a mobile node which is very near to the tower may get the chance to transfer the packets immediately. But, a mobile node which is far away from the tower may not get the chance to transfer the packets immediately. In other words, it is unfair to serve the packet which is started later than the packet which is started early. The packet which is started early must be served first. This paper proposes a QoS algorithm to eliminate / reduce this issue and to reduce jitter in mobile networks. Ultimately, it helps to increase Quality of Service in mobile networks. © 2011 Springer-Verlag Berlin Heidelberg.
