Wireless technology is the strongest contender for catering for the 5G backhaul stipulated performance where optical fibre is unavailable. In the presence of ultra-dense networks, such occurrences are exponentially increasing and different wireless technologies are investigated for this application. We present the first backhaul-specific wireless link performance modelling that considers its inherent line-of-sight nature, together with an appropriate representation of the network topology using stochastic geometry. To this end, novel tractable models are obtained to capture the performance of wireless backhaul links. These are integrated into a multi-hop hybrid backhaul performance modelling framework and are applied in the analysis of a backhaul-aware user association optimisation problem.
The backhaul is a cornerstone in the development of future cellular networks and not the least challenging. The difficulty of designing the future backhaul is in the expected range of performance metrics that is increasing in breadth and in rising standards. Novel ideas for solving the heterogeneous backhaul problem are frequently proposed. Tractable analytical models that capture the performance of such backhauls are crucial in order to verify and validate these ideas. We present the first modular and scalable framework for analytically modelling the performance of hybrid multi-hop backhauls, which employs technology-specific models of different performance aspects of each hop.

Backhaul has for years been taken for granted by all but a relatively small group of technicians and engineers who manage,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
