Device-to-Device (D2D) communication has been proposed as a promising implementation of green communication to benefit the existed cellular network. In order to limit cross-tier interference while explore the gain of short-range communication, we devise a series of distributed power control (DPC) schemes for energy conservation (EC) and enhancement of radio(More)
This paper proposes a method for improving the precision of Network Traffic Prediction based on the Maximum Correntropy Criterion (NTPMCC), where the nonlinear characteristics of network traffic are considered. This method utilizes the MCC as a new error evaluation criterion or named the cost function (CF) to train neural networks (NN). MCC is based on a(More)
Overlay networks have emerged as a useful approach to providing a general framework for new applications and services that are to be implemented without significantly changing the IP-layer network infrastructure. Overlay routing has been used as an alternative to the default best effort Internet routing for the absence of end-to-end Quality of Service(More)
Femtocell is a promising technology for improving indoor coverage and offloading the macrocell. Femtocells tend to be densely deployed in populated areas such as the dormitories. However, the inter-tier interference seriously exists in the co-channel Densely Deployed Femtocell Network (DDFN). Since the Femtocell Access Points (FAPs) are randomly deployed by(More)
We have proposed a call admission control in LTE-Advanced relay system which is based on resource sharing. Each cell has 7 sites, including 1 eNB and 6 relay stations, if the shared resources are used up for handover users and new users in the requested site, handover users can use the reserved resources of the requested site, while new users can utilize(More)
Multiple controllers are connected to each other to construct a scalable SDN (Software Defined Network) control plane, and every switch is connected to a dedicated controller in data plane. The load on controllers changes dynamically in accordance to the services varying in switches; and switches need to be migrated from their master controllers to slave(More)
Device-to-Device (D2D) communication has been proposed to facilitate cellular network with system capacity (SC) and quality of service (QoS). We consider the design of link assignment (LA), channel allocation (CA) and power control (PC) in D2D-aided content delivery scenario for both user fairness (UF) and system throughput (ST) under QoS requirement. Due(More)
In this paper, we concentrate on the problem of routing and bandwidth assignment in GMPLS networks. We proposed a new restoration routing algorithm in GMPLS networks with optimized bandwidth. In this new algorithm, we consider multiple network optimizing objectives to setup a LSP with maximize profit and shortest path under the limited resources. By(More)
In order to improve survivability of Multi-Domain Optical Network (MDON) and differentiate service reliability, this paper provides a Protection mechanism with Differentiated Service Reliability in MDON based on Conditional Risk Disjunction Degree (CRDD), called PDRC. Firstly, defines CRDD, provides Intra-domain virtual links Reflection arithmetic based on(More)
The goal of web service composition is to choose an optimal scheme according to Quantity of Service (QoS) which selects instances in a distributed network. The networks are clustered with some web services such as ontologies, algorithms and rule engines with similar function and interfaces. In this scheme, web services acted as candidate service construct a(More)
