The emerging mobile WiMAX (IEEE 802.16e) has gained serious attention as a means of providing wireless broadband access to mobile users. 802.16e supports high data rates and QoS for various applications, and is thus a powerful contender for next generation wireless access technology. On the other hand, IEEE 802.11 a/b/g/n have already been widely used to provide high data rates in a limited area....
The demand on capacity and quality offered over wireless communication links has pushed researchers to innovate new design methodologies and concepts over wireless systems and networks with the ultimate aim towards achieving a next generation network (NGN). Among the emerging technologies is the radio on free space optics (RoFSO) system described in this paper. With this technology it is possible...
A new VoIP (Voice over Internet Protocol) capacity expansion method with periodically frame suppression control is proposed. The proposed method expands a VoIP capacity of an AP (Access Point), which is the maximum number of associated stations without critical QoS (Quality of Service) degradations. Simulation results show the proposed method with 0.5% frame suppression control on each station expands...
Recent rapid developments of high-speed wireless access technologies enable us to use real-time multimedia services as well as legacy non-real-time services via wireless access systems. These multimedia services require QoS (Quality of Service), such as low PLR (Packet Loss Rate) and short delay time. To provide QoS guarantee in wireless LAN (Local Area Network) environment, this paper proposes a...
Recent rapid developments of high-speed wireless access technologies cause WLAN environments where QoS supported APs and not QoS supported APs are mixed. To provide optimal QoS guarantee in this mixed environment, this paper proposes AP selection agent system and its selection algorithm for mixed environment. In the system, agents equipped on some servers, APs and STAs in a network which cooperate...
This paper proposes AP selection schemes for QoS guarantee in Wireless LAN. hi the scheme, QoS information server provides the information to guarantee QoS to mobile terminals. Simulation results show throughput improvement than the conventional load balancing scheme.
