The IEEE 802.16e standard, also known as mobile WiMAX, has emerged as an exciting mobile wireless communication technology that promises to offer both high throughput and guaranteed quality of service (QoS). Call admission control (CAC) scheme serves as a useful tool for WiMAX, which ensures that resources are not overcommitted and thereby, all existing connections enjoy guaranteed QoS. Existing CAC...
According to different priority based services, IEEE 802.16e WiMAX standard classifies packets as UGS, RTPS, eRTPS, nRTPS, BE. The standard treats all packets generated while browsing the internet as delay tolerant packets and classifies them as Best Effort (BE) packets. This includes BE packets generated while browsing secure websites. However, secure transactions are governed by time constraints...
As advanced integrated network architecture, ldquocognitive radio technologies,rdquo which aim to improve the spectrum efficiency, have been studied. In the cognitive radio networks, each node recognizes radio conditions, and according to them, optimizes their wireless communication routes with the integration of the heterogeneous wireless systems not only by switching over them but also aggregating...
IEEE 802.16 standard defines the broadband wireless access specification for WiMAX, but it did not specify a standard scheme for scheduling algorithms and admission control. As a result, we propose an uplink scheduling scheme called Random Early Detection based Deficit Fair Priority Queue (RED-based DFPQ) for WiMAX. RED-based DFPQ adjusts the deficit counter of rtPS based on the current queue length...
IEEE 802.16/WiMAX is an emerging standard for broadband wireless networks. It operates in both point-to-multipoint (PMP) and mesh modes. In the former, a number of subscriber stations communicate directly with a central base station. Although it supports different traffic classes characterized by distinct QoS requirements, the simplest is the best effort traffic. In this class, the subscriber stations...
