Energy‐Efficient Incentives Resource Allocation Scheme in Cooperative Communication System

Abstract

Appropriate resource allocation has great significance to enhance the energy efficiency (EE) for cooperative communication system. The objective is to allocate the resource to maximize the energy efficiency in single-cell multiuser cooperative communication system. We formulate this problem as subcarrier-based resource allocation and solve it with path planning in graph theory. A twolevel neural network model is designed, in which the users and subcarrier are defined as network nodes. And then we propose an improved intelligent water drops algorithm combined with Genetic Algorithm; boundary condition and initialization rules of path soil quantity are put forward. The simulation results demonstrate that the proposed resource allocation scheme can effectively improve the energy efficiency and enhance QoS performance.

Green IoT for Eco-Friendly and Sustainable Smart Cities: Future Directions and Opportunities

“…Maximizing the power-efficiency was by relay station with subcarrier for an orthogonal frequency division multiple access. However, the energy efficiency was optimized by using an energy-efficient incentive resource allocation technique for enhancing the cooperation of communication networks [123], in which the combination of genetic and water drops method for improving energy consumption effectively and efficiently.…”

Major Cloud Computing Security Challenges with Innovative Approaches

“…Cloud safety, moreover referred to as cloud computing safety, comprises a difficult and rapid of rules, strategies, controls, and generation that art work altogether to defend cloud-based completely systems, reality, and configuration [1][2][3]. Those protection capabilities are configured to defend cloud reality assist governing compliance and defend clients' privacy further to establishing validation laws for person clients and tools [4][5][6]. From validating get proper of access to selecting traffic, cloud safety can be arranged to an appropriate desire of the business.…”
