TL;DR: This work addresses the technical challenges of optimally allocating users' cloud requests to MTC and TPC data centres to meet users’ QoS requirement with minimum cost and solves the optimization problems using linear programming based branch-and-bound and LP with rounding.
Abstract: Mobile Telecom Cloud (MTC) refers to cloud services provided by mobile telecommunication companies. Since mobile network operators support the last-mile Internet access to users, they have advantages over other cloud providers by providing users with better mobile connectivity and required quality of service (QoS). The dilemma in meeting higher QoS demands while saving cost poses a big challenge to MTC providers. We tackle this challenge by strategically placing users’ data in distributed switching centres to minimize the total system cost and maximize users’ satisfaction. We formulate and solve the optimization problems using linear programming (LP) based branch-and-bound and LP with rounding. Furthermore, we discuss MTC brokerage which allows MTC providers to act as a brokerage to broker third-party cloud providers’ (TPC) cloud resources and integrate the resources reserved from TPC with those of their own MTC. We address the technical challenges of optimally allocating users’ cloud requests to MTC and TPC data centres to meet users’ QoS requirement with minimum cost. We also study the price range that can be profitable to a MTC brokerage. We then investigate the resource reservation problem with dynamic request changes. We evaluate our solution using real Google traces collected over a 29-day period from a Google cluster.

TL;DR: In this article, the authors address reliability and availability of power infrastructure in telecom core and data centers, and special attention is given to modelling of solar and wind power sources in terms of availability as well as their implementation into critical infrastructure.
Abstract: This paper addresses reliability and availability of power infrastructure in telecom core and data centers. Special attention is given to modelling of solar and wind power sources in terms of availability as well as their implementation into critical infrastructure. Influence on overall electrical reliability and availability of infrastructure is shown in different topologies. Architecture of the topologies is based on both alternating current (AC) and direct current (DC) 400V distributions. Results of reliability and availability calculations derive from models based on dynamic Fault Tree Analysis (FTA).

TL;DR: In this article, the authors found out that network infrastructure sharing leads to significant reduction in cost of network infrastructure rollout in the rural areas for telecoms operators in Benue State, and recommended to the Federal Government to speed up its power sector reforms, as doing so will bring great relief to the infrastructure sharing.
Abstract: With the high demand for quality service by telecom users, combined with the heated competition of a gradually maturing telecom market in Nigeria, some telecom operators are led to explore ways of reaching their potential customers in a very cost efficient and cost effective way. The main objective of this study is to find out if network infrastructure sharing results in a significant reduction in cost of network infrastructure rollout and capacity expansions for telecoms operators in Benue State. The study respondents consists of senior technical, rollout managers, finance/accountant and adminstrative staff cadre of MTN and GLO working in Benue State. The population of this category of staff in GLO is 120, while MTN is 170, making a total of 290 respondents. The sample size is 168. Multiple-Regression is a multivariate statistical technique was employed to predict the established relationships between the variables. The study fond out that that network infrastructure sharing leads to significant reduction in cost of network infrastructure rollout in the rural areas for telecoms operators in Benue State. Network infrastructure sharing eliminates some setup costs such as land acquisition cost, civil works cost, and tower construction cost as well as long and tedious bureaucratic processes of seeking permits. This helps in rapid rollout to new areas while drastically reducing cost of network expansion cost by over 50 per cent. This helps in improvement on time to market. Network infrastructure sharing reduces operational costs such as electricity and security among others leading to operational efficiency. Rural infrastructure sharing is strongly recommended (both 2G and 3G) in Benue State because majority of the population are living in rural areas. The main recommendation is in respect of the epilepsy power supply. It is recommended to the Federal Government to speed up its power sector reforms, as doing so will bring great relief to the infrastructure sharing in Benue State. The tariffs charged by the telecom operators for their services will be drastically reduced and quality of services provided by the operators will also improve tremendously.
