Abstract:

Cloud-radio access Network (C-RAN) develops as an answer for fulfill the interest for an assorted scope of utilizations, enormous availability, and system heterogeneity. C-RAN utilizes focal cloud arrange for handling client demands. Effective administration of cloud assets (e.g., calculation and transmission assets) is one of the significant difficulties in C- RAN. In this work, noble approach is been proposed of workload allocation between small cell and microcell of H-CRAN (Heterogeneous Cloud-Radio Access Network). This proposal is been verified by the simulation model designed in INET 4.2 under OMNET ++ 5.5.1. The simulation results show that proposed method illustrate better result than existing method in terms of Access Point Power (AP Power), Diversity Gain and End-to-End Delay (E2E Delay).

Description:

Our proposed architecture is to balance the workload between macro cells and small cells. There has been extensive study of small cells and heterogeneous cell structures in the literature. A detailed survey and deployment of small cells in LTE and UMTS network have been studied in [4]. The authors in [5] provides an overview of the key drivers and major challenges for small cell deployment and demonstrate how densification can be complemented by advanced MIMO and small cells to accommodate the anticipated traffic demand. The architecture of small cell network combined with LTE wireless network has been reviewed in [6] along with performance evaluation and future deployment scopes with 5G network. Cambridge University Press published an excellent source for understanding small cells in 5G mobile network [7]. The book includes the architecture, configuration and application of all facets of the small cell network. It also discusses emerging trends, priorities for research resource management, energy efficiency, performance analysis, implementation approaches, standardization practices, environmental concerns, and maintaining mobility in heterogeneous small cell networks. In [8] The authors talked about the development and deployment of small cells as well as the technical challenges associated with small cell network design, deployment and optimization. They also discussed main operational aspects such as bandwidth availability, mobility management, interruption control, energy efficiency, backhaul, deployment planning, frequency allocation / access method and heterogeneous network management. Numerous studies have been carried out on the use of small cells. Most of these studies are operations, administration, network control, intrusion management, LIPA (Local IP Access), connectivity and design.
