This paper discusses the design challenges associated with supporting advanced mobility services in the future Internet. The recent transition of the Internet from the fixed host-server model to one in which mobile platforms are the norm motivates a next-generation protocol architecture which provides integrated and efficient support for advanced mobility services. Key wireless access and mobility...
Information-Centric Networking (ICN) has a great potential to better support the content distribution over the future Internet. Meanwhile, users with mobile devices will also access ICN, introducing a new challenge to ICN providers to handle such mobile content requests. In this paper, a mobility and popularity-based caching strategy is proposed to increase the cache hit rate through WiFi while people...
As the unprecedented growth of mobile data traffic places significant strain on cellular networks, alternative plans for exploiting already existing and under-utilized wireless infrastructure, become quite attractive. In this paper, we study cellular-to-mesh (C2M) data offloading for LTE-A cellular mobile users to WiFi mesh networks, which are built and managed collaboratively by users. Such networks...
Named Data Networking (NDN) is a promising information-centric future Internet architecture. Its innovative concepts, like named content, name-based routing and in-network caching, particularly suit the requirements of the Internet of Things (IoT), interconnecting billions of heterogeneous constrained objects. NDN supports receiver-driven communications and can easily enable IoT pull-based applications,...
This paper presents an end-to-end algorithm for detecting a shared congested router in the internet when communication is established using multiple paths between wireless devices endowed with multiple interfaces (e.g., LTE, and WiFi). The proposed technique is based on one way end-to- end delay observation of packets received through multiple paths at the end hosts to infer whether or not the flows...
In this paper we propose, implement and evaluate a bandwidth aggregation service for residential users that enhances the throughput of their Internet broadband connection through the aggregation of available capacity at neighboring broadband links. Network resources are aggregated by the residential access gateway using the 802.11 radio interface to simultaneously serve home users and to share the...
Internet and its applications have become an integral part of today's human lifestyle. It has become an essential tool in every aspect. Due to the tremendous demand and necessity, researchers went beyond connecting just computers into the web. These researches led to the birth of a sensational gizmo, Internet of Things (IoT). Communication over the internet has grown from user — user interaction to...
Wireless mesh network (WMN) has emerged as a key technology because of their advantages over other wireless networks. Due to the dynamic infrastructure, the traffic volume of the WMN goes in an increasing order, thus balancing the load of the network becomes very crucial. Hence the problem of load balancing is addressed in this paper and for which the cluster based architecture of WMN is considered...
In this paper, we address the problem of Road Side Unit (RSU) deployment in urban environments. One of the main goals in designing a Vehicle-to-Infrastructure (V2I) network is to find optimal locations for deployment of all the RSUs. The objective in our case is to cover all the road parts that have the highest car density using a limited number of wireless access points (the number of available RSUs...
Providing broadband passenger internet on board trains with continuous connectivity at high speeds and over large rural distances is a challenging issue. One solution to the problem is to use an onboard WiFi network connected to multiple 3G and 4G networks deployed outside the train and aggregate their combined capacity at the IP protocol level. In order to be able to provide the capacity and the...
The Stream Control Transmission Protocol (SCTP) is a transport layer protocol introduced to complement the well known User Datagram Protocol (UDP) and the Transmission Control Protocol (TCP). The current implementation of SCTP heavily leverages some existing mature techniques from TCP. This paper studies the effect that RTOmin (retransmission timeout minimum) has on the selective acknowledgement (SACK),...
This paper presents an experimental deployment of a multi-channel wireless backbone network (WBN) with an Open Flow-based traffic management framework. In a WBN, a set of APs, each of which uses a single and different channel, is connected by Ethernet and thus constructs a VAP handling multiple channels. To flexibly control traffic flow transmitted over multiple channels, we also implement a traffic...
Universal access to Internet is crucial, and as such, there have been several initiatives to enable wider access to the Internet. Public AccessWiFi Service (PAWS) is one such initiative that takes advantage of the the available unused capacity in home broadband connections and allows Less-than-Best Effort (LBE) access to these resources, as advocated by Lowest Cost Denominator Networking (LCDNet)...
Wireless hotspots allow users to use Internet via Wi-Fi interface, and many shops, cafés, parks, and airports provide free wireless hotspot services to attract customers. However, there is no authentication mechanism of Wi-Fi access points (APs) available in such hotspots, which makes them vulnerable to evil twin AP attacks. Such attacks are harmful because they allow to steal sensitive data from...
The “Union of the Comoros” is a volcanic archipelago nation in the Indian Ocean, consisting of three islands. About half the population lives below the international poverty line of US$1.25 a day. The interiors of the islands vary from steep mountains to low hills with mostly damaged or unconstructed roads to interconnect the several islets. This situation represents an extraordinary field test: the...
Wireless Sensor Network (WSN) usage for buildings and household has been increasingly popular because it offers various benefits, such as home automation and home surveillance. Therefore, in order to increase WSN usage flexibility, remote controlling which enables remote administration is required. In fact, generally WSN is controlled by a coordinator (sink node) that is located closely to the WSN...
In this paper we describe the design and implementation of an experiments dealing with SDN for Wireless Mesh Networks over the OpenLab Facility. The experiment is called EXPRESS: “EXPerimenting and Researching Evolutions of Software-defined networking over federated test-bedS”. EXPRESS aims at designing and evaluating a resilient SDN system able to operate in fragmented and intermittently connected...
The eHealth technology will change the way the health system is handled, mainly in developing countries, such as Brazil, where there is a huge shortage of healthcare professionals to assist the patients, especially for those living in rural and remote areas. The Context-Aware Mobile Approach (CAMA) seeks to improve the Brazilian primary healthcare system through context-aware eHealth facilities, such...
Wireless embedded Internet (WEI) is a new research trend nowadays, with a focus on developing new wireless embedded end devices, network protocols, optimized models of intelligent context management, as well as the integration of WEI applications to the Internet. However, current approaches are still lack of a dimension, i.e., cost-effective WEI solution at a reasonable price for developing market...
The goal of this work is to design and implement a new system that allows the user to apply his/her every day motor skills to simulate games. This system adds to the known gaming techniques the physical benefits as well as the real interaction between user and machine. Moreover, the gamers around the world can benefit from this project as well as the people who need physical rehabilitation .The latter...
