Adapter Implementation between Wimax Specific Layers and Network/Application Layers

Several recent studies show that future high data rate broadband wireless access (BWA) technologies require the use of adaptive and co-operative techniques to more efficiently utilise the resources in link and system level. In this paper we propose an adapter module to be utilised in the data link layer (DLL) and optionally in the application layer to serve different adaptive triggering routines among the networks. The adapter is used to retrieve the necessary information from hardware (HW) to aid different adaptation processes in system. The adapter is also used to trigger the preferred control and management actions in the media access control (MAC) and physical (PHY) level of the related HW. The usability and performance limits of the designed and implemented adapter solutions were measured with relevant performance evaluations and the derived results validate the feasibility of the proposed adapter solution.
