Nowadays there is an increasing need of broadband communications anytime, anywhere for users requiring multimedia services with quality of service support. This paper deals with the integration of GEO satellite networks and terrestrial wireless networks. Our interest is for a DVB-RCS GEO system integrated with a WiFi terrestrial segment based on the IEEE 802.11b and e standards. Such a scenario is...
The wireless channel-oriented ad-hoc multi-hop broadband (W-CHAMB) is a new link layer protocol with the aim of being able to support quality of service (QoS) in multi-hop operation in fully distributed ad hoc networks. It is based on time division multiple access (TDMA) technology, operating on a single frequency channel. In this paper, we improve the prioritized access mechanism by inserting the...
This paper considers the feasibility of operating both IEEE 802.11b (Wi-Fi) and 802.16a (Wi-Max) networks in the same shared frequency band. A specific method using the "CSCC" (common spectrum coordination channel) etiquette protocol is studied and compared with earlier results on reactive interference avoidance algorithms. The CSCC concept is outlined, and its application to this particular...
