In this paper, we investigate a cross-layer routing framework for centralized multi-hop cognitive radio networks in TV white spaces. Our Cross-layer routing focuses on joint spectrum allocation and power control. The problem is mathematically modeled as mixed integer nonlinear program that requires an appropriate solution methodology. We examined a solution based on nonlinear terms relaxation in conjunction...
4G/5G Heterogeneous Networks (HetNets), which are expected to have a very dense multi-layer network structure, have emerged as a solution to satisfy the increasing demand for high data rates. These networks, similar to other networks, are subject to failures of communication components, which may occur due to many reasons. Self-Healing (SH) is the ability of the network to continue its normal operation...
