| dcterms.abstract | There is a significant interest in designing new wireless multiple access protocols that split a wide frequency channel into multiple sub-channels and assign these sub-channels to competing transmissions. Doing this adaptively depending on the number of competing transmissions has a tremendous potential both in high-speed and white-space networks. While such protocols have been developed, they suffer from limitations such as considerable protocol overheads, dependence on a centralized controller, and assumptions about the network being static, etc. In this work, we develop a new multiple access protocol, Ez-Channel, that adaptively and efficiently channelizes the spectrum for improving throughput, without encountering the limitations of the past solutions. Ez-Channel performs efficient channelization and assignment of sub-channels to links by resourcefully utilizing the OFDM sub-carriers. In addition to circumventing hidden and exposed terminal problems, Ez-Channel adapts channel assignments whenever the topology or direction of links change in the network. In order to eliminate the need for a centralized controller and to avoid an overwhelming amount of information exchange, the protocol takes advantage of randomization techniques that facilitate localized decision making at nodes. Our extensive analytical and simulation studies show that Ez-Channel yields significant throughput improvements as compared with the state-of-the-art protocols in various settings. | |
