RESEARCH OUTLINE

In recent years the use of mobile devices for communication has increased. The mobile users now expect a variety of services from a mobile communication network that include uni-modal data and voice services to multimodal multimedia services. The mobile users often demand the same quality-of-service available to the fixed users. In practice, voice services are sensitive to delay but can allow some loss. On the other hand, data services like E-mail and web browsing etc. are tolerant to delay but are very sensitive to data loss. The multimedia services require specified quality-of-service but can gracefully degrade and also upgrade their quality-of-service depending upon the congestion on the network.  

Quality-of-service provisioning over wireless networks becomes difficult due to users’ mobility, finite resource limitations, and widely varying resource requirements. To provide uninterrupted service to delay sensitive applications, it is required to determine the users’ mobility profile for resource reservation. Admission control is required to handle congestion and to guarantee quality-of-service to the admitted calls in a wireless network. It is found that when the mobility rate of the mobile users is low, it results in wastage of scarce wireless bandwidth. Thus admission control and resource reservation schemes need adaptation based on users’ mobility and also the kind of application they are using.

Some of these issues and findings are disseminated in the following publications.
