The main objective of this paper is to propose a frame work for improvising the service of multimedia applications in mobile networks. The framework has been proposed with a Cross-Layer Manager (CLM) and a Cross-Layer Coordinator (CLC) for improvising of multimedia applications by dynamically adapting the bandwidth under prevailing channel conditions. Cross-Layer coordination among Application, MAC and Physical layer has been achieved along with bandwidth adaptation that improvises the Quality of Experience (QoE) of multimedia applications. The performance of the framework has been tested using GloMoSim and the results for the proposed framework under different scenarios show an improvement of 16% in throughput. It is also observed that the framework provides 5% improvement in multimedia service when compared with the cellular system containing only homogeneous traffic calls.
