“…This way, a data connection can finish its service quickly by using whenever possible high amounts of bandwidth. Some works in literature have implemented this feature, see for example [14]; however, it is unfeasible in practice to assume that a connection can use all the available bandwidth. For instance, in a given moment a data connection can use 100Mbps!…”

IEEE 802.16 standard or WiMax network is one of the new alternatives for broadband wireless access. Among its promising applications is the creation of a wireless backhaul support for WiFi traffic. In this context, it is mandatory to design a Call Admission Control in the WiMax Base Station for resource allocation for the integration of both network technologies. In this paper, we investigate this subject by proposing an optimal call admission control and resource allocation for WiMax and WiFi integration. The optimization problem is formulated as a Semi-Markov Decision Process. By presenting a comprehensive analysis, we discuss different design trade-offs alternatives.

“…In this paper, the heterogeneous wireless networks architecture [24][25][26][27][28] is proposed not only to facilitate the connection between wireless networks of different protocols but to extend QoS transparency successfully in the procedure of vertical handoff. In this section, QoS classes of the two main heterogeneous wireless networks (WiMAX and WiFi) are presented.…”
