In recent years, software-defined networking (SDN) has been adopted in practice, such as the fast-growing market of software-defined wide area networks (SD-WAN). Intent, an emerging concept for SDN, aims to provide a simple interface for operators to manage the network. Under the framework of intent, an application submits a request by specifying the objective only, and the SDN controller decides...
This paper analyzes the transmission capacity of D2D (Device-to-Device) network in cellular and D2D heterogeneous networks(HetNets) with cellular users (CeUEs) assisted. The D2D network capacity can be enhanced by allocating a part of CeUE transmission power to assist D2D communication. By utilizing stochastic geometry, we first model the HetNets by homogeneous Poisson point process (HPPP). Secondly,...
Device-to-Device communication enables high-speed services in the traditional cellular networks but brings potentially mutual interference. In this paper, the heterogeneous network of D2D and IMT-Advanced in a single cell is considered, where the D2D communication is assumed to share the uplink resource with cellular user. The definition of mode selection is first introduced and then a novel distance-dependent...
There are much unstructured data in all kinds of application systems. It is very important to manage these unstructured data and transform them into structured data. XML language is very suitable for data storage and data exchange. Data transformation utility was developed using Microsoft Visual Studio 2005. The textual data in Microsoft word table files can be transformed into text file, the data...
