Exploring power consumption reduction in centralized radio access for energy‐efficient centralized‐Internet of Things implementation

Abstract

The advent of new wireless and Internet of Things (IoT) technology has increased the dependency on the cellular base stations (BS). The rapid growth in IoT and wireless devices impinges many challenges on cellular services providers and manufacturers. The Centralized Radio Access Network is an energy and cost-efficient solution for the next-generation BS architecture. In this article, we have proposed a centralized-IoT (C-IoT) architecture based on centralized BS (C-BS). We evaluated different base station technologies and compared the C-BS with the traditional distributed BS (D-BS) architecture for power consumption. A mathematical model for power consumption for both types of BS is proposed. We have analyzed the impact of variation in traffic load on power consumption for both types of BS architecture. The simulation result shows that C-BS architecture has the potential to save around 40% to 50% energy compared with D-BS architecture.

Prediction of Power Consumption Utilization in a Cloud Computing Data Centre using Kalman Filter parameters with Genetic Algorithm

“…In the proposed ASUS, the decision whether additional equipment will be activated is a function of size of traffic arrivals. The traffic arrival to the DC is assumed to follow Poisson distribution, and the probability that 𝑛 number of packets arrives at the time interval ∆𝑡 is given as [22]:…”

“…The ASUS aims to minimize power wastage by adaptively activating and deactivating equipment in the DC as the need arises. Thus, the ASUS is modelled as an optimization problem, and the model equation is expressed as: The constraint (22) indicates that the power consumed by equipment 𝑞 cannot exceed the rated power consumption for an equipment in the DC. Constraint (23) indicates that the inter-arrival time (∆𝑡) must not exceed two hours.…”

A Power-Aware Method for IoT Networks with Mobile Stations and Dynamic Power Management Strategy

“…In [16], several ways of decreasing the energy consumed in centralized radio access were investigated for energy-efficient IoT applications. To communicate with IoT devices, radio access must be centrally managed rather than having each device communicate directly with the network.…”

“…Whereas, more focus of scientists is to replace brown energy with green energy where ever possible. In every field of research, energy efficiency is the core issue 7‐11 …”

“…In every field of research, energy efficiency is the core issue. [7][8][9][10][11] Energy consumption of data centers is expected to double every 5 years. 12 Increasing energy consumption in data centers is not only becoming critical issue for service providers as it is an important factor in operational expenditures, it is also catching attention of environment watchdogs.…”
