Parsimonious traffic-descriptor for QoS routing decisions in Bluetooth network

Traffics from real-time, high-speed, multimedia, and interactive applications are bursty and are known to
associate with self-similar property. It has a direct impact on network performance. Link characteristics
may also contribute to the network performance, particularly when routing decisions are to be made at a
router node to select its forwarding link. Therefore, if the source traffic and the link quality can be precisely
characterized for resource allocation and reservation at the time of routing, a better level of QoS guarantee
could then be granted to user applications in a resource-limited Bluetooth ad hoc network. However, the problem lies in the formulation of a mathematical model that can incorporate least possible parameters but well describing the application requirements, such that efficient and reliable QoS routing decisions are achieved. Thus, this work aims to develop a parsimonious traffic-descriptor, which will be used intermediately for resource reservation and ultimately for QoS routing decisions at a router node. The performance of the traffic-descriptor is observed through a Matlab simulation. It was found that the traffic descriptor has described the source traffic and the link quality with fairly good precision.
