We propose a routing protocol for drive-thru Internet access in delay tolerant vehicular networks. The contribution of this paper is two-folds. First, we propose a new approach which utilizes the concept of delay tolerant network (DTN) to supplement the conventional communication approach. Second, we propose an algorithm to schedule DTN transmissions in order to maximize the system throughput. The...
Distributed and cooperative caches (DCCs) enabled small-cell network (SCN) has been a common approach for improving QoE perceived by mobile users (UEs) and reducing backhaul traffic load. In this paper, we propose a joint wireless and backhaul load balancing (JWBLB) framework for DCCs enabled SCNs with the objective to minimizing the system content transmission delay. The JWBLB is achieved through...
The main node (router, coordinator, gateway) of ZigBee based wireless sensor network enhanced by adoption of Bluetooth module is proposed in this paper to provide easy way for industrial field measurement with low-cost and portability. Only a Bluetooth module and basic circuits are required to be added to the original ZigBee network and a simplified physical model is designed and verified in wireless...
In this paper, wireless deployment scenarios for network operators delivering broadband Internet access in underserved rural areas lacking adequate basic PSTN network infrastructure are examined. Considering the defined operators' broadband coverage targets, the existing national regulatory demands and the EU initiatives engaged in a Digital divide reduction, further deployment of broadband access...
The Metropolitan Area of Caracas, Venezuela, has a geographical distribution such that almost every middle-class and wealthy neighborhood is located next to at least one barrio -- informal squatter settlements. We propose a Wireless Mesh Network (WMN) that exploits the urban geography of the city, so some poor families could gain access to the Internet via one or more Internet Service Providers contracted...
A Wireless Internet-access Mesh NETwork (WIM-NET) provides the scalable and reliable internet access through the multiple access points (APs) and wireless relay communications. In particular, by redundantly deploying APs in the network field, the WIMNET becomes robust to the link or AP failure. However, these redundant APs increase the power consumption, and thus the number of active APs should be...
The Connected Revolution has reached the automotive industry and the Internet penetrates into the modern vehicles. Formerly acquiring data from a vehicle was the tool of Fleet Management Systems handling commercial vehicles. In the recent years connectivity began to appear in the passenger vehicles also. The first features were infotainment and navigation, having low security needs remaining far from...
Within the Internet of Things (IoT), Smart Things (STs) promise to permeate all contexts of daily life, offering digital access to their physical functionality. Mobile users then would be able to ubiquitously and spontaneously interact with things they encounter, enabling a wealth of diverse usage scenarios and applications. Currently, however, ST interaction requires a pre-controlled Internet or...
Today, Cloud Computing and the Internet of things are two “major forces” that drive the development of new Information Technology (IT) solutions. Many Internet of things (IoT) based large-scale applications rely on a cloud platform for data processing and storage. However, big data generated or collected by large-scale geo-distributed devices needs to be transferred to the cloud, often becoming a...
Next-generation wireless networks entail a high degree of flexibility, efficient use of available radio resources and an energy-efficient operation at low operational costs. They typically integrate use of technologies such as spectrum management, interference mitigation and management, and energy efficient technologies to deliver the broadband experience. This paper aims to project the 2020 broadband...
As vehicles become increasingly intelligent, it is expected that in the near future they will be equipped with radio interfaces. This will enable the formation of vehicular networks, commonly referred to as VANETs, an instance of mobile ad hoc networks with cars as the mobile nodes. As VANETs exhibit several unique features (e.g. high mobility of nodes, geographic extension) traditional security mechanisms...
We propose a method for regulating wireless access points (APs) that is based on mechanisms of biological development and evolution. The purpose of the proposed regulation is to simultaneously achieve power savings in the APs and achieve reliable connection services through the APs better, which is shown to be a trade-off relationship in this study. The regulation target is the cycle time at which...
This paper investigates user provided networks. Such networks have become important research in the field of informatics engineering due to the recent popularity of smart phones. User provided networks are independent from traditional Internet service providers. Communication and information exchange between users occurs opportunistically, i.e., when the smart phones are close enough to exchange information...
Internet of Things in which object, animal, people is identified uniquely according to their identifier in the network and data transfer over Network without having directly human to human or human to machine interaction. IoT is used in education to improve E-Learning. It is available in different formats. Propose a system combining the different applications of e-learning with the help of Internet...
The IEEE INFOCOM community has looked to large-scale computer networking testbeds such as PlanetLab, Emulab, and ORBIT to fulfill an essential role in the testing and validation of innovative ideas. Until very recently, testbeds such as these have existed in separate silos, each with its own authentication mechanisms and experiment support tools. The OneLab experimental facility breaks down the barriers...
Wireless mesh network (WMN) has been proposed to extend wireless coverage by using multi-hop communication to enable network service for mobile devices via densely deployed mesh APs. While modern wireless devices are capable of using multiple WiFi interfaces, the Multipath TCP (MPTCP) protocol has been employed to make full use of the capacity of multiple radios. A key question of MPTCP communication...
When a large-scale disaster occurs, it is crucial to secure means of communication. However, as the damage to the communication networks might be aggravated as the magnitude of the disaster becomes larger, it would likely cause a state where all communications are disrupted. In addition, as the amount of damage to the power plant and transmission line becomes more significant, it could disrupt the...
Mobile communication devices are expected to overtake traditional desktop PCs and become the dominant point of entry to the Internet. This technology shift has boosted user demand for multimedia applications and services which are now typically accessed through the wireless interface. Users expect to be always connected and able to run a variety of applications which sometimes impose contrasting requirements...
Computer-centered services and broadband wireless connectivity have boosted the demand for delivery of multimedia-based entertainment from the Internet to in-house wireless appliances. In this context, rich-media applications can be supported by a variety of protocols, each sharing the same bottleneck, affecting one another's performance. Indeed, in current systems, real-time applications (e.g., video...
Wireless standardization activities such as the Bluetooth V4.x (Bluetooth smart) have led to an explosive growth in innovative short-range wireless devices capable of providing various services to assist everyday life. Allowing Machine-to-Machine (M2M) communication between these M2M devices also enable new commercial service opportunities. The M2M service providers including telecom carriers may...
