Abstract
Incorporating distributed subcarrier allocation (DSCA) capability into WNW will improve operational effectiveness and allow WNW networks to operate under more restrictive spectrum constraints. Phase I of this project will establish the technical feasibility of DSCA by accomplishing the following. 1) Establish a state-of-art baseline in subcarrier allocation and net control technology, referring to multiple standards - at least 802.22, the 802.16 family, CogNeA, WPAN protocols, and LTE.802.22, 802.16xx standards. (Task 1) 2) Synthesize candidate dynamic subcarrier allocation strategies and algorithms for OFDM based wireless WNW networks experiencing a variety of possible link conditions including geographically localized narrowband/partial band interference, time varying channels with frequency selective fading, strong neighbor interference and shadowing. The solutions will consist of cross layer subcarrier allocation in the SiS, MDL, and MI layers as well as communicating with neighboring nodes and maintaining network stability. (Task 1, 2) 3) Generate a technology insertion plan for inserting distributed subcarrier allocation schemes into WNW. (Task 2) 4) Identify implementation issues that would be encountered at the SiS, MDL, MI, & Network layers by introducing these schemes and candidate solutions to those issues Test/evaluate and rank the candidates in terms of performance benefit, ease of implementation and compatibility with WNW-OFDM architecture. (Task 4)
