In this paper, we propose using software-defined networking technologies for optimal traffic engineering in cellular networks with service chaining. We study the case in which virtual machines are used to support network services and each flow requires multiple network services. To minimize the maximum load of virtual machines and guarantee that the sum rate of admitted flows is large enough, we formulate...
WebRTC-based applications are assumed to be based mostly on peer-to-peer communication, where an instance of the application is talking to another instance. However, this is not always the case: a WebRTC-based application communicating with a legacy VoIP device or Media Server like a Video Conference Server is also very common. The ability to make both types of communications (WebRTC to WebRTC and...
The LTE “Long Term Evolution” technology was introduced to reduces the DATA network latency, in addition to provide higher data throughput. But the nature of LTE prohibits the transmission of voice related services. VoLTE “Voice over LTE” is a solution to transfer voice packets with special treatment over the LTE network, and get benefits from its low latency and quality of services capabilities to...
This paper presents mechanisms that have the potential for dramatically reducing end-to-end delay in mobile networks. We introduce a simple algorithm for dynamic user plane gateway placement in a mobile network. The proposed algorithm is able to optimize gateway location according to given targets, e.g., path latency or bottleneck link load. We shall also present how active queue management can be...
Generally, the project reveals about the semantic web services based implementation of home appliances into ZigBee coordinators network. Certain studies have been conducted based on the same project. All those studies provided a static environment which was not applicable for dynamic system interactions. In all the previous papers only conventional web services are being used. We have an architecture...
Traditional database information and IoT real time data are now evolving to unified paradigms in whose accessing diverse data endpoints can be challenging due to interoperability problems that emerge when instant data are monitored and collected in typical database scenarios. In this paper, a new model is proposed to link persistent data with instantaneous information using publish-subscribe networks...
Nowadays, Internet video is the dominant internettraffic. DASH is an adaptive video streaming technique introducedto enable high quality video delivery over HTTP. In homenetworks, multiple video streams will compete for bandwidth, thus leading to poor performance and impacting the receivedquality of experience. In this paper we introduce a new techniqueto address this issue at the home network gateway...
Emergency Rescue Information Sharing System supports rescue operations in early stage by gathering information about victims in need of help at the time of disaster. In this system, in-vehicle relays are used to gather extensive information. In-vehicle relays transmit information sent by mobile terminals to a database server via gateway switches. There are several wireless connections between relays...
The Internet of Things (IoT) has advanced in different directions, including the development of new architectures, platforms and applications. This multidirectional progress has resulted in the creation of several parallel IoT ecosystems called verticals. Therefore, several approaches have proposed solutions for interoperability of these ecosystems through the delivery of services over virtual infrastructure...
PPSS is a central primitive introduced by Bagherzandi et al. [2] which allows a user to store a secret among n servers such that the user can later reconstruct the secret with the sole possession of a single password by contacting t + 1 (t.
Cloud computing is a rapidly growing computation paradigm. Cloud Computing combines all the Information Technology (IT) capabilities. As it has turned into the standard for cloud suppliers to have numerous server farms the world over, noteworthy requests exist for between server farm's information moves in extensive volumes, e.g., relocation of huge information. A test emerges on the best way to plan...
This paper introduces a network operation and management system for Korean fir ecosystem monitoring. Its purpose is to collect information on the habitat surrounding environment, including soil moisture, tree diameter growth of information, based on wireless sensor network which is one of ICT technology. The environmental information including temperature, humidity, illuminance, Co2, rainfall, soil...
Injecting faults into designs is a way to qualify a verification environment. To improve the performance of a qualifying process, we need to remove identical faults. The problem will provide some faulty design cases; the contestants must identify all sets of identical faults. The judgment will be based on correctness, execution time and memory usage. The topic mainly belongs to gate level design.
Disasters are inevitable aspects of the human civilization and the limitation of extending the medical infrastructure to every corner of the demography is a challenging task. Technology can cater to need of the availability of medical expertise for each affected individual in the disaster virtually. A medical infrastructure can be envisioned using existing LAN and WAN communication technology standards...
Content Delivery Networks (CDN) act as trusted overlay networks that offer high-performance delivery of common Web objects, static data and rich multimedia content by distributing content load among edge servers which are close to the clients. And the interconnection of different CDNs (called CDNi) could provide more advantages and benefits to both content provider and client than a single CDN during...
In this article, we present a system for energy measurement at mains sockets. It consists of several smart energy measuring devices (SEMD) that use a low-power radio protocol to dynamically build and connect to a radio network to transfer power usage date to a server. At the server, the data is stored and can be accessed via web interface. Our primary goal was to build a back-end system for an energy...
Air quality is an essential factor to assess the health and life quality of people. However, air pollution has become an acute problem in major cities of developing countries due to the rapid industrialization and poor handling of air pollutants. In this scenario, air quality monitoring practices have been scarcely implemented largely because of the relatively high cost and technical complexity of...
In the last years, the Machine-to-Machine (M2M) communications evolved as one of the major trends shaping the development of services in the future Internet. The use of M2M technologies is rapidly increasing in different fields such as Health Care, Automotive, Energy, Consumer Electronics, manufacturing, security and Banking. With that rapid increase different protocols had been developed for M2M...
Now-a-days the role of Information and Communication Technology (ICT) to develop and strengthen the sector of agriculture has become seemingly promising. ICT can help a farmer to get relevant information regarding different agricultural information like crop, diseases, marketing, etc. Also, studies have depicted that mobile phone penetration in Nepal have increased in the recent years. This have opened...
In this study, we propose a method for improving the scalability of sharing the flow rules, which are used to inspect and direct packets, between gateway functions in a mobile network virtualization infrastructure. The proposed method enhances the centralized management mechanism, where a controller reactively installs rules based on receiving the first packet of each flow, to reduce the load in the...
