However, due to the limited number of radios and available orthogonal channels, designing efficient channel assignment and scheduling algorithms in such networks is a major challenge. In this paper, we present provably-good distributed algorithms for simultaneous channel allocation of individual links and packet-scheduling, in software-defined radio (SDR) wireless networks. Our distributed algorithms are very simple to implement, and do not require any coordination even among neighboring nodes. A novel access hash function or random oracle methodology is one of the key drivers of our results. With this access hash function, each radio can know the transmitters{\textquoteright} decisions for links in its interference set for each time slot without introducing any extra communication overhead between them. Further, by utilizing the inductive-scheduling technique, each radio can also backoff appropriately to avoid collisions. Extensive simulations demonstrate that our bounds are valid in practice.}, keywords = {access hash function, Channel allocation, channel assignment algorithm, channel capacity, collision avoidance, Computer science, cryptography, distributed algorithm, distributed algorithms, Educational institutions, inductive-scheduling technique, Interference, interference set, packet scheduling algorithm, Peer to peer computing, Radio network, radio networks, radiofrequency interference, random oracle methodology, scheduling, Scheduling algorithm, simultaneous channel allocation, software radio, software-defined radio wireless network capacity, telecommunication congestion control, telecommunication security, Throughput, wireless channels, Wireless networks}, isbn = {978-1-4244-3512-8}, doi = {10.1109/INFCOM.2009.5062069}, author = {Han,Bo and Kumar,V.
