In wide area ubiquitous wireless networks, most wireless terminals (WTs) will transmit small amounts of data at comparatively long intervals. Therefore, each AP must be capable of accommodating a great many WTs. Moreover, these networks must accommodate a variety of services; Quality of service (QoS) guarantees are essential. In this paper, we propose a novel QoS control scheme based on random access...
We propose a packet scheduling algorithm to improve the throughput performance of non-real time (NRT) traffic while satisfying quality of service (QoS) of real-time (RT) traffic in orthogonal frequency division multiple access (OFDMA) system compared to the conventional algorithm. In order to support both RT and NRT packets adaptively in the varying traffic situation, the proposed algorithm adjusts...
In the wide area wireless network, most wireless terminals will send small amounts of data with very long transmission intervals. Therefore, each access point must accommodate a large number of wireless terminal and devices. Moreover, the network is required to accommodate a variety of wireless terminals, so quality of service (QoS) needs to be guaranteed. In this paper, we propose a new QoS control...
