Nexgen Technology provides final year IEEE projects for 2015-2016. It is located in Pondicherry, India and specializes in projects related to scheduling in cognitive radio networks. The document describes several graph-theoretic scheduling problems including: 1) A polynomial-time algorithm for throughput-maximizing scheduling. 2) The NP-Hardness of max-min fair scheduling and an approximation algorithm. 3) The NP-Hardness and inapproximability of proportionally fair scheduling.
