A number of algorithmic and protocol assumptions taken for granted in the design of existing
wireless communication technologies need to be revisited in extending their scope to the …

To increase the utilization of the available frequency channel space in 802.11-based
wireless mesh networks, recent work has explored solutions based on multi-radio stations …

This work presents a TDMA based multi-channel MAC protocol called TMMAC for Ad Hoc
Networks. TMMAC requires only a single half-duplex radio transceiver on each node. In …

Software defined radio (SDR) capitalizes advances in signal processing and radio
technology and is capable of reconfiguring RF and switching to desired frequency bands. It …

We describe HyMAC, a new hybrid MAC layer protocol for wireless sensor networks that is,
to the best of our knowledge, the first effort to combine the strengths of both TDMA and …

Recently, the CR (cognitive radio) technology is gathering more and more attention because
it has the capacity to deal with the scarce of the precious spectrum resource. Within the …

Economies of scale make IEEE 802.11 an attractive technology for building wireless mesh
networks (WMNs). However, the IEEE 802.11 protocol exhibits serious link-layer unfairness …

This paper is mainly concerned with multichannel transmission of real-time information such
as video over multihop ad hoc links. We propose two multichannel routing protocols. The …

Cognitive radios (CR) technology enables wireless devices to dynamically switch between
channels in a wide range of frequency bands and utilize unused parts of licensed and …

Simulation is the most famous way to study wireless an mobile networks since they offer a
convenient combination of flexibility and controllability. However, their largest disadvantage …
