Predictions abound on the growth of mobile data traffic driven by smart phones and tablet PCs that come with an expectation of broadband Internet connectivity everywhere and a demand for high quality video. The FCC's National Broadband Plan indicated that mobile data traffic in North America would increase by roughly 20 to 45 times between 2009 and 2014, and current data suggests these numbers may...
The web caching business has significantly changed over the recent years. The percentage of content that is suitable for caching has constantly decreased, e.g. due to unfavorable content formats like Flash or varying URLs due to usage of CDNs. While this of course has a negative impact on the effectiveness of caching, also other parts of the equation have changed: Transmission cost has dropped significantly,...
The following topics are dealt with: autonomic event computing; user-provided networking; broadband single carrier; HeterWMN mobile networks; HeterWMN wireless sensor networks; femtocell networks; exploiting shared media; aerial channel analysis and physical data links; handover and network selection in future broadband networks; performance modelling; coding for memories; cognitive radio, VANET and...
Mobile WiMAX is a rapidly growing broadband wireless access technology based on IEEE 802.16e-2005 air-interface standards. It provides high-speed internet service anytime, anywhere, from anyone and any device with seamless mobility and the service is located between mobile phone and wireless LAN. For special activities purpose, we have developed Mobile WiMAX communication systems for UGV (Unmanned...
The optical and wireless communication systems convergence will activate the potential capacity of photonic technology for providing the expected growth in interactive video, voice communication and data traffic services that are cost effective and a green communication service. The last decade growth of the broadband internet projects the number of active users will grow to over 2 billion globally...
This presentation describes the importance of communication network infrastructure to support the achievement of European Union policy goals, economic growth and employment. The future Internet will run on a high-speed broadband optical fibre infrastructure. Research is required to match the requirements of users, applications and services to the capabilities of the infrastructure.
In order to fulfil the demand for on-the-move and uninterrupted internet connectivity in Mobile Networks, the IETF (Internet Engineering Task Force) has standardized NEMO Basic Support Protocol in as RFC 3963. However, providing a low latency handoff performance in mobile networks by using fast handover mechanism to ensure a seamless mobility for users is one of the main objectives of ongoing research...
Digital convergence has received increasing attention in recent years due to innovations of information technology, broadband usage of mobile communications, and Internet services. There are no distinguishable differences among operators of fixed-lines, mobile, or cable TV. In the current telecommunications market, companies provide more than one service or product, as the industry becomes more complex...
The emergence of wireless communities offers an attractive alternative to operator-centric models for providing broadband wireless services. While the first attempts of purely self-organized communities have been limited by the difficulty of attracting enough members willing to share their resources with the community, newer hybrid wireless communities (where a firm supports and incentivizes individuals...
Although much literature exists on how technology can promote tourism industry, little is known about this phenomenon in developing countries. The existing technologies have not been able to successfully tackle the infrastructural and connectivity problems. To tackle the challenges, the use of low cost and simple technologies is imperative. This paper therefore discusses the role of wireless broadband...
The rapid evolution of broadband wireless Internet access in the recent years has been accompanied by a plethora of devices and applications that allow mobile users to work remotely or stay in touch with their friends as they go. With the increasing demand for ubiquitous access and the notion of being "always connected", the limitations of today's Internet technologies have become obvious,...
Mobile broadband services quickly emerged in some of the countries. This trend provides a rich opportunity for mobile video services. As the 3G services and data flat-rate services penetrate, various mobile video services emerge in Japan. The author presents the new business model examples that emerge. The author discusses the implications of the current mobile video service business in Japan. The...
Employing multiple TFRC connections has emerged as a promising lightweight way of coping with wireless channel losses in a congestion-controlled tandem network. This work extends multiple TFRC connection streaming to broadband uplink streaming. This study differs from earlier work for a number of reasons: it reports on a specific wireless technology, IEEE 802.16 (WiMAX); it considers the impact on...
An open onboard Internet system model based on the centralized access mode is designed for the m-commerce on train which is easy to merge the oncoming broadband wireless access and network technologies.The functionalities and entities in each layer are investigated and the hot issues are discussed according to this model. It is shown that the onboard Internet applications including the m-commerce...
Mobile networks and services have grown dramatically since digital networks were introduced in the early nineties. Now operators want to provide broadband services over the Internet to mobile and wireless users. The pressure on the transport network will increase dramatically, and more cost effective solutions for the backhaul are urgently needed. This includes both physical layer and higher protocol...
Idea of accessing broadband services from already deployed WiFi APs while travelling at vehicular speed has gained considerable popularity among the researchers. Random location of APs makes it difficult to get continuous Internet connection. As a result, a mobile node moving at vehicular speed faces periods of connections and disconnections; this intermittence is termed as "disruption"...
Today broadband Internet access is often regarded as an important and strategic factor for enterprises, private households, and for the medical and the educational sector. Be-sides increased quality of life and service, the broadband Internet access has a strong economical impact for the selected region, e.g. on the inducement for settlement especially for enterprises. Un-fortunately, still today...
The objective of this work is to provide the main elements to support the fact that Mexico has not increased its levels of competitiveness and it neither has equaled to other countries in the region. It is required to implement comprehensive reforms in sectors such as education, infrastructure, healthcare, information technologies and telecommunications, among others. As a result of this analysis,...
Operators around the world are improving their 3G/UMTS networks by introducing HSPA (High Speed Packet Access) that includes both, enhanced uplink and downlink. The HSPA is expected to finally provide the mobile broadband access that is able to compete with the fixed connections in performance regarding popular applications such as Web browsing, VoIP, and video. However, it has remained unclear how...
