Because of the high cost of construction and maintenance of infrastructure-based networks, researchers have concentrated their efforts on studying wireless mesh/relay networks with lower cost and high scalability. Due to the demand for real-time multimedia communication in heterogeneous networks, IEEE 802.16 multi-hop mesh/relay networks with IEEE 802.11e WLANs for QoS support can be an effective...
Various vehicular communication technologies have been proposed to provide reliable and seamless wireless communications. Short-range vehicular communications can be established using IEEE 802.11p, and the range of these protocols can be extended using mobile multi-hop ad hoc networks. To provide consistent quality of service (QoS) with maximum achievable transmission rate, many algorithms assume...
we apply the concept of the common spectrum coordination channel (CSCC) etiquette protocol to form a spectrum sharing protocol among access points in 802.11 networks. It efficiently allocates operating frequencies among access points. As a result, it reduces interference from wireless devices using the 802.11 MAC/PHY protocol. This is motivated by the lack of intelligent spectrum sharing among Wi-Fi...
A relay station (RS) in IEEE 802.16j mobile multi-hop relay (MMR) networks provides access links to far-off subscriber stations (SSs) and hidden subscriber stations. The RS also relays data from a base station and other RSs while maintaining backward compatibility with legacy subscriber stations in existing IEEE 802.16 networks. Much research is being performed to finalize the standard; however, how...
