	abstract = {In a Cognitive Wireless Mesh Network (CogMesh), each Cognitive Radio (CR) enabled mesh node can sense and opportunistically access the under-utilized spectrums in the primary system. Since the unoccupied spectrum is location-dependent and time-dependent, the available spectrums in each mesh node are different. With this spectrum heterogeneity, each node shall have the knowledge of spectrum, scheduling, and routing path of other nodes such that it cacommunicate with them with minimal cost and no collision. The problem may occur in a number of the situations, e.g. the routing table re-building and the unicast real-time applications. In this paper, we focus on the 2-hop spectrum scheduling, which will enable any pair of 2-hop neighborhood nodes know the spectrum, collision-free scheduling, and minimal-cost routing path. Two optimal strategies are proposed to address the spectrum scheduling: Optimal Deterministic Spectrum Scheduling (ODS) and Optimal Randomized Spectrum Scheduling (ORS). In the deterministic situation, with the scheme ODS, the 2-hop spectrum scheduling can be solved in polynomial time. In the randomized situation, with the scheme ORS, the 2-hop spectrum scheduling can be solved in polynomial time with high probability at least (1-\frac{1}{n}) where n denotes the network size. The simulation experiment is carried out to show the achievable performance of the proposed algorithms.},

	abstract = {Fixed WiMAX is being deployed worldwide, and the networks are increasing in size. Measurements have been performed, but the amount of measurements are few and do therefore not demonstrate performance in a real life deployment. We have performed extensive analyses of the physical performance in a fixed WiMAX deployment which has been operative for a year and where the amount of subscribers constantly increases. The analyses presented in this paper focus on received signal strength and signal to noise ratio. Based on the measured parameters, we present a Path Loss model for fixed WiMAX which will hopefully be of great reference value due to the great amount of measurements presented. Finally, our Path Loss model is compared to other well known Path Loss models and is found to approach the free space loss model.},
