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...
An alternative WLAN protocol which could be adapted in the HCF access scheme defined by IEEE 802.11e, in place of the HCCA mechanism, is introduced. LEPOAC-QG (low energy priority oriented adaptive control with QoS guarantee) is a centralized access mechanism that supports low energy consumption, guarantees QoS for all types of multimedia network applications, enhances the parameterized traffic with...
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...
