Undergraduate courses for data communications and telecommunications cover services from a network technology perspective more so than they cover network technologies from a service perspective. Thus, critical issues such as interoperability and end-to-end system integration in support of new service and application ideas are left unexplored until post graduation, on-the-job training. Up until now,...
An important challenge in cellular IP networks, which deals with the micro mobility, is providing good quality of service (QoS) to the users especially to the real-time users that are involved in the exchange of real-time packets. Bandwidth reservation for real-time traffic to maximize the connection completion probability (CCP) is an important activity. Genetic algorithm (GA), which is a useful tool...
In face of heterogeneous RATs coexisting in next generation communication system, the network selection is related to Cooperative Radio Resource Management (CRRM) and QoS requirements of traffics and users' preference etc to give the best choice for the users. Based on the proposed MAC layer architecture which set Cooperative RRM manager, in this paper the Differentiated Traffics Relative Band Request...
With growth of Internet and wireless IP network, multimedia systems can be accessed from any-where and anytime. However, efficient real-time services are open and challenging research problem. To implement real-time services such as VoIP over wireless access network, IP header compression scheme can be used for saving bandwidth. Enhanced compressed RTP (ECRTP) has been used for lossy link and high...
