Mobile ad hoc networks (MANETs) are useful in environment where fixed network
infrastructure is unavailable. To function normally, MANETs demand an efficient and …

Physical carrier sensing is an effective mechanism of medium access control (MAC)
protocols to reduce collisions in wireless networks, and the size of the carrier sensing range …

In the emerging IEEE 802.11 e MAC protocol, the enhanced distributed channel access
(EDCA) is proposed to support prioritized QoS; however, it cannot guarantee strict QoS …

IEEE 802.11 is the most important standard for wireless local area networks (WLANs). In
IEEE 802.11, the fundamental medium access control (MAC) scheme is the distributed …

IEEE 802.11 MAC protocol has been the standard for wireless LANs and is also
implemented in many simulation software for mobile ad hoc networks. However, IEEE …

Recent studies have shown that the performance of wireless multihop ad hoc networks is
very poor. In this paper, we first demonstrate that one important reason of the poor …

Opportunistic spectrum access and adaptive power management are effective techniques to
improve throughput, delay performance, and energy efficiency for wireless networks. In this …

Recent years have seen greatly increasing interests in voice over IP in wireless LANs, in
which the IEEE 802.11 distributed coordination function protocol or enhanced DCF protocol …

We derive the access delay generating function of the IEEE 802.11 DCF protocol. Our
analysis corrects a model recently presented by O. Tickoo and B. Sikdar (see Proc. IEEE …

With the rising popularity of wireless multimedia applications and the adoption of IEEE
802.11 access technologies in mobile ad hoc networks, admission control and bandwidth …
