—Machine to Machine (M2M), communication between the machines without or with the least-human involvement, is going to be an important part of life. Healthcare is one of the areas on which M2M is going to play major roles. At present time, healthcare sensors monitor patient information and notify remote doctors. However, if we can integrate more(More)
—We study the demand response (DR) of geo-distributed data centers (DCs) using a dynamic pricing scheme. Our proposed pricing scheme is constructed based on a formulated two-stage Stackelberg game where each utility sets a real-time price to maximize its own profit in Stage I; and based on these prices, the DCs' service provider minimizes its cost via(More)
—Traditional Internet is merely static, rather than flexible, which is demanded by Internet-Community. OpenFlow has opened the door of management of Internet in a more controlled way. In this context, we are motivated to manage OpenFlow in a more opportunistic way, which encourages flexible network-management by using experience, through trial and(More)
—Internet has grown very rapidly in the last couple of decades and still growing because of the expansion and utilization of various services and applications. Consequently, demand of delay and throughput sensitive services, like audio/video is also increasing. Information Centric Networking (ICN) is proposed as an architecture for the future Internet to(More)
—Cognitive Radio Network (CRN) is one of technologies to enhance the spectrum utilization by allowing unlicensed users to exploit the spectrum in an opportunistic manner. In CRN, the spectrum handoff function is a necessary component to provide a resilient service for the unlicensed users. This function is used to discover spectrum holes in a licensed(More)
In this paper, we consider distributed power control schemes for downlink co-tier interference coordination in a two-tier heterogeneous network consisting of multiple femtocells under the coverage of a macrocell. We formulate a non cooperative game in order to solve this problem. First we propose an algorithm in which all femto access point simultaneously(More)
Heterogeneous cognitive wireless networks (HeCoNets)) are consisted of macrocells that are overlaid by small cells (e.g, femtocells, picocells). These small cells operate over the cognitive radio paradigm. In this paper, we consider a cooperative model in the uplink of HetCoNets, that includes picocell and famtocells networks that are using unlicensed(More)
