Abstract:
The Network Utility Maximisation (NUM) framework is one of the most widely investigated approaches for designing the resource management system for wireless mesh networks. In order to perform the NUM-oriented per-flow network resource management, data flows have to be recognised and classified. Relevant solutions that are constituents of the state-of-the-art NUM frameworks are insufficient, since they are able to differentiate between various network flows only according to the transport layer protocol used. The paper describes improvements introduced to an existing DANUM System (DANUMS) implementation. They provide means for flexible flow classification enabling more accurate utility estimation for more diverse types of flows. The solution improves DANUMS’ ability to assign appropriate utility functions suitable for different types of traffic. The experiments show that the enhanced framework enables improving the performance of the DANUMS.
