Multihop wireless networks will play an important role in future communication networks. Beamforming antennas have shown great potential to improve the connectivity in these networks; however only heuristic approaches exist to assess the benefits of this technology. Using the popular “keyhole” antenna model, we formulate a Mixed Integer Program (MIP)(More)
This paper investigates the diverse routing problem in the presence of shared risk link groups (SRLGs) and proposes two ILP models for partial SRLG-disjoint protection based on grouping of the individual SRLGs in classes. We demonstrate our approach with SRLGs constructed from seismic maps, hence reducing the likelihood of a single earthquake affecting(More)
Adhoc networks will play an important role in future access networks. Previous studies have shown, that the connectivity of such networks can be notably increased by employing directional antennas. Heuristic methods to control the direction of these antennas based on local information exist, however it remains unclear, how well they perform. This work tries(More)
