Dynamic channel allocation (DCA) and transmit power control (TPC) are known as efficient tools to accommodate the explosive demand for broadband wireless access services, by utilizing the limited radio resources while satisfying predefined quality of service (QoS). However, the high complexity of the interactions between discrete DCA and continuous TPC renders a close-form solution to the joint optimization...
Due to their popularity, dense deployments of wireless local area networks (WLANs) are becoming a common feature of many cities around the world. However, with only a limited number of channels available, the problem of increased interference can severely degrade the performance of WLANs if an effective channel assignment scheme is not employed. Previous studies on channel assignment in WLANs almost...
Emerging high-density WLANs in urban areas and enterprises offer great potential to accommodate the anticipated explosion of demand for wireless data services. To make it successful, it is critical that the network utilizes the limited radio resources efficiently while satisfying predefined quality of service (QoS) requirements. In this paper, we develop a real time and open ended algorithm for joint...
In this paper we evaluate the performance of our earlier proposed enhanced relay-enabled distributed coordination function (ErDCF) for wireless ad hoc networks. The idea of ErDCF is to use high data rate nodes to work as relays for the low data rate nodes. ErDCF achieves higher throughput and reduced energy consumption compared to IEEE 802.11 distributed coordination function (DCF). This is a result...
