Examples include cellular networks, metropolitan area networks and wireless local area networks. Given the heterogeneity of the existing network technologies, the diversity of mobile applications, and user requirements, ensuring service continuity for a mobile user when changing different access network becomes a mandatory aspect. The aim of this work is to study and analyse a solution based on the IEEE802.21 standard, to enable interoperability between different networks. The assessment takes place in a context of mobility between WiFi and WiMAX networks. The network simulator NS2 is used during this study.}, isbn = {978-1-4673-1520-3}, author = {Benkaouz, Yahya and Angoma, Blaise and Erradi, Mohammed}, editor = {Essaaidi, M and Zaz, Y} } @conference { ISI:000300570200017, title = {HaVe-2W3G: A Vertical Handoff Solution between WLAN, WiMAX and 3G Networks}, booktitle = {2011 7TH INTERNATIONAL WIRELESS COMMUNICATIONS AND MOBILE COMPUTING CONFERENCE (IWCMC)}, series = {International Wireless Communications and Mobile Computing Conference}, year = {2011}, note = {7th IEEE International Wireless Communications and Mobile Computing Conference (IWCMC), Istanbul, TURKEY, JUL 04-08, 2011}, pages = {101-106}, publisher = {IEEE; IEEE Turkey sect; Huawei}, organization = {IEEE; IEEE Turkey sect; Huawei}, abstract = {The demand for the ubiquitous service is increasing due to the rapidly growing demand for increased data rates, mobile Internet and the diversity of wireless communication technologies. Also due to the challenges to interconnect heterogeneous network technologies and to offer ubiquitous services, telecommunications operators look after the best way to provide continuity of service during handover and how to give the mobile client the possibility to get the best connection anywhere and anytime. In this paper we propose an architecture and its implementation which guarantees the continuity of service during a communication in the context of heterogeneous access network technologies. The suggested solution named HaVe-2W3G (Handover Vertical WLAN WiMAX 3G) ensures a Vertical handover between heterogeneous access networks technologies: WLAN, WiMAX and 3G. A performance evaluation of such implementation is shown using a streaming application.}, isbn = {978-1-4244-9537-5}, issn = {2376-6492}, author = {Angoma, Blaise and Erradi, Mohammed and Benkaouz, Yahya and Berqia, Amine and Akalay, Mohammed Charaf} } @conference { ISI:000259298000004, title = {Fairness and QoS in ad-hoc networks}, booktitle = {2008 IEEE 67TH VEHICULAR TECHNOLOGY CONFERENCE-SPRING, VOLS 1-7}, series = {IEEE Vehicular Technology Conference Proceedings}, year = {2008}, note = {67th IEEE Vehicular Technology Conference, Marina Bay, SINGAPORE, MAY 11-14, 2008}, pages = {16+}, publisher = {IEEE}, organization = {IEEE}, abstract = {IEEE 802.11 is a standard for Wireless Local Area Networks. Recent works show that this standard has bad performances in ad-hoc mode. In this paper, we analyze the algorithm used by the standard to manage contentions and propose an alternative algorithm to resolve fairness issues observed in the Hidden terminal scenario. Using., NS-2 simulator we show that our algorithm has better throughput management based on fairness between nodes under QoS constraints required by each node.}, isbn = {978-1-4244-1644-8}, issn = {1550-2252}, doi = {10.1109/VETECS.2008.16}, author = {Berqia, Amine and Angoma, Blaise} }
