Distributed routing schemes for multi-hop fixed relay networks
Weiwei Wang, Jun Cai, Attahiru Sule Alfa · 2009
In this paper, two distributed routing schemes, named adaptive information moving rate (AIMR) and adaptive information moving distance and link rate (AIMDLR), are proposed for multi-hop fixed relay networks. Both routing schemes aim to maximizing spectral efficiency in terms of throughput-oriented spectral efficiency (TOSE) and fairness-oriented spectral efficiency (FOSE), respectively, while remaining distributed properties without involving network-wide information. Moreover, the route convergence issue which is inherent to some distributed routing schemes is also discussed by proposing a new routing convergency (RC) scheme. Simulation results demonstrate that the proposed routing schemes can significantly improve the spectral efficiency with high convergency probability.
