“…Coverage planning serves to determine the number of sites needed based on the coverage area in the case study. In coverage planning, maximum allowed pathloss (MAPL) is calculated using as (2). Where 𝐸𝐼𝑅𝑃 is effective isotropic radiated power (dBm) which can be calculated using as (3), RS is receiver sensitivity (dBm) which can be calculated using as (4), IM is interference margin (dB), 𝐿 𝑅𝑋 is reception losses (dB), 𝐺 𝑅𝑋 is reception gain (dB), 𝐹𝑀 is fading margin (dB), 𝑃 𝑇𝑋 is transmission power (dBm), 𝐺 𝑇𝑋 is antenna gain (dB), and 𝐿 𝑇𝑋 is transmission losses (dB).…”

<span>The increasing demand for telecommunication services causes data traffic density. Therefore, in this research, the long-term evolution (LTE) network expansion was carried out using a choice of frequency bands of 700 MHz, 2100 MHz, and 2300 MHz. The analysis was carried out from the technical and economic aspects. Frequency band recommendations were obtained using the simple multi-attribute rating technique (SMART) method. This research was conducted using a case study of Semarang City. Based on the simulation results, the average of reference signal receive power (RSRP) values for frequency 700 MHz and 2300 MHz is in the very good range, while the frequency of 2100 MHz is in the good range. The signal to interference noise ratio (SINR) values for the three frequencies are in the normal category and the throughput values are in the very good category. The techno-economic calculations of the three frequencies, namely the value of internal rate of return (IRR), net present value (NPV), and payback period are included in the business category that is feasible to do. Based on the ranking results, the 700 MHz frequency is the most superior, both in terms of technical and economic aspects.</span>

“…In order to further improve the efficiency of the algorithm and reduce the number of illegal individuals, this paper proposes the illegal solution adjustment mechanism. For the illegal solution, the probability CP is equal to the optimal solution, as shown in Equation (9), where K 5 is a normal number less than 1.…”

“…Network coding allows intermediate nodes to combine the received information during information transmission and then pass the result information to the next node. Network coding technology can effectively improve network throughput [6], enhance network robustness [7], and increase the utilization of wired and wireless networks [7][8][9], meaning that the multicast rate can reach the upper limit of the maximum flow minimum cut theory [10,11].…”

The problem of network coding resource optimization with a known topological structure is NP-hard. Traditional quantum genetic algorithms have the disadvantages of slow convergence and difficulty in finding the optimal solution when dealing with this problem. To overcome these disadvantages, this paper proposes an adaptive quantum genetic algorithm based on the cooperative mutation of gene number and fitness (GNF-QGA). This GNF-QGA adopts the rotation angle adaptive adjustment mechanism. To avoid excessive illegal individuals, an illegal solution adjustment mechanism is added to the GNF-QGA. A solid demonstration was provided that the proposed algorithm has a fast convergence speed and good optimization capability when solving network coding resource optimization problems.

“…As a highly promising technology for optical networks, EONs have been extensively studied in the literature including their resiliency provisioning [13,14,15]. In terms of smallscale failures (i.e., a single or several elements failure), mainly dedicated/shared path-based and p-cycle methods were applied regardless of the failure reason.…”

“…In the next step, 2S-RSA moves to the spectrum assignment phase (Alg.3, lines 12-17), which handles demands in the same order as previously. For each of the selected paths p ∈ P d , 2S-RSA finds first free spectrum channel (i.e., channel characterized by the minimum last slice index) and allocates demands (Alg.3, lines [14][15].…”

The telecommunication networks have become an indispensable part of our everyday life, providing support for such important areas as business, education, health care, finances, entertainment and social life. Alongside their continuous and uninterrupted operation is required while numerous new threats and attack scenarios emerge. The international security organisations warn against increasing likelihood of nuclear weapon or electro-magnetic pulse (EMP) attacks, which can be extremely harmful also for transport networks. On that background, we study efficient design of network resilient to EMP attack wherein the required protection level is provided by the application of multipath routing and military grade bunkers (advanced electro-magnetic radiation resilient approaches protecting whole network node) implementation. Formally, we define and study problem of bunkers location, routing and spectrum allocation (BLRSA) in elastic optical network (EON). In the problem objective we address two criteria -network resilience (measured by the average lost flow per potential attack) and spectrum usage. For that problem we propose integer linear programming (ILP) model and two dedicated heuristics -1S-RSA and 2S-RSA. Then, we perform extensive numerical experiments divided into three parts: (i) tuning of the proposed approaches, (ii) comparison with reference methods, (iii) realistic case study -efficient EMP-resilient network design. In the case study we analyze benefits and costs of the proposed protection scheme. Moreover, we also analyze vulnerabilities of three realistic network topologies to EMP attacks and identify their critical nodes. The investigation proves high efficiency of the proposed approaches and shows that they allow to save up to 90% of traffic lost in the case of no protection against these types of attacks.
