DEMONSTRATING THE SYNERGY BETWEEN CAC AND SCHEDULING IN WIRELESS NETWORKS

Wireless technology is now an integral part of communication network infrastructure. From their first beginnings, such as connection-oriented General System Mobile networks for voice traffic only and connectionless wireless local area networks for data traffic, new generation wireless networks are connection-oriented and provide differentiated services to the user. With the arrival of more sophisticated services and mobility, have arisen the need for Connection Admission Control and traffic scheduling in the network to enhance the quality of experience (QoE) of the user and optimizing the revenue in dynamic workload environments. A great deal of research effort has gone into the study of the performance of one such network standard, namely the IEEE 802.16 networks. Most optimization studies focus on scheduling (a very mature subject in computing) and ignore connection admission (a very mature subject in telephone engineering) or vice versa. In this paper we claim that one should not study the two in isolation and provide empirical evidence to prove our claim.
