“…For the first each commercial building has a BBU hotel linked to the PON backhaul and the hybrid fiber/copper fronthaul, which is spread within the building. For the second it is assumed that some buildings located along parallel diagonal lines which cross the scenario, have a small outdoor mobile cell (pico cell) at their diagonal top which is connected by optical links to a BBU, thus forming a chessboard pattern of outdoor cells with regard to the buildings and ensuring a line of sight is provided to the outdoor user [Lopes et al 2015]. In this way, in peak traffic data rates of 1 Gbps and 144 Mbps can achieved by indoor and outdoor users, respectively.…”

Fifth generation (5G) cellular networks will be the key element of a society that is becoming increasingly interconnected and digitalized. Applications adopted in many social and industrial sectors will require from 5G networks higher standards of availability and reliability. These requirements are leading operators to plan the deployment of protection schemes in the backhaul layer. In this context, our aim is to employ simulation to assess in a technical and economic way different backhaul protection schemes based on passive optical network (PON). The results indicate that the use of protection can increase the viability of 5G networks based on a PON backhaul supporting a hybrid fronthaul with fiber and copper.

“…What is neglected in the above works is that small cells operation can inflict a hefty traffic load to the backbone network [23][24][25][26] imposing also a considerable power burden to the system. Some researchers have pointed out its importance since backhaul (BH) consumption may vary from 30% to very high levels, which is comparable to the consumption levels of operating the macrocellular (macro) BSs [27][28][29][30].…”

Capacity overprovisioning in mobile networks leads to underutilization of network resources and thus inefficient operation from a power consumption perspective. In addition, as operators constantly evolve their networks to denser heterogeneous layouts, with overlaying macrocellular base stations coexisting with numerous smaller cells, to cope with upcoming increase in peak mobile data traffic, the energy consumption of mobile networks will continue to grow in the next years. In this context, although backhaul connections can be responsible for tremendous power consumption, the corresponding study is usually neglected in most of the recent energy related literature. An approach for fast and low cost connectivity of dense microcellular sites is the deployment of wireless in-band backhaul links via existing macrocellular base stations. In this paper, we consider this wireless in-band backhaul approach, where access and backhaul links share the same frequency spectrum, and examine joint energy efficient resource optimization on both links. We introduce an iterative low-complexity polynomial backhaul-aware heuristic, which directs traffic to the most energy efficient network resources, and compare it against i) an exhaustive search method that provides optimum results, Engineering, Vol. 6 4, 337-368. doi: 10.13052/jge1904-4720.641 c 2017 338 G. Kyriazis and A. Rouskas ii) a previously proposed reference algorithm, and iii) ordinary Full Operational Topology (FOT) network, where no energy aware technique is applied. From the results obtained, we conclude that our heuristic achieves high energy efficiency gains in all scenarios examined, while wireless in-band backhaul method proved a solid choice for this purpose.
