As one of the promising broadband wireless access technologies, IEEE 802.16 mesh networks need to guarantee the QoS requirement from users. But unfortunately, traditional congestion control strategies cannot work well in this kind of network, due to lack of precise congestion indication and the unique characteristics of shared wireless media. In this paper, a novel but rational congestion control...
In this paper, we present two simple-to-implement measurement-based admission control methods for real-time services in IEEE 802.16e networks. The first method simply utilizes the averaged number of free slots as input in admission decisions while the second method is more advanced and it tunes the admission thresholds according to current traffic load. Our simulations show that the proposed methods...
Ethernet passive optical network (EPON) and worldwide interoperability for microwave access (WiMax) are two promising broadband access technologies for next-generation wired and wireless access network. The integrated architecture of complementary EPON and WiMax technologies combine the benefits of optical fiber capacity and wireless network mobility. In this paper, we propose a dynamic bandwidth...
IEEE 802.16, a standard for wireless MAN broadband access technology, provides a flexible QoS mechanism in MAC layer for wild variety classes of services. However, it fails to define specific admission control strategy and scheduling algorithm, therefore, those aspects about QoS guarantee mechanisms are becoming the research hotspot in recent years. In this paper, focusing on the features of services...
