In this letter, we propose a novel cooperative caching scheme for the next-generation Internet — content oriented networking (CON), trying to minimize the content access delay for mobile users. We formulate the caching problem as a mixed integer programming model and propose a heuristic solution based on Lagrangian relaxation. Simulation results show that this scheme can greatly reduce content access...
Resolution from identifiers to locators serves as a key component of mapping-based mobility solutions. In this paper we address the weakness of current resolution methods in supporting diverse mobility scenarios and propose a Global Resolution Service offered by Resolution Service Providers. We present a preliminary design and simulation, and results show that our approach is able to provide better...
The growing number of mobile devices equipped with a wireless interface and the end-user trend to shift toward wireless technology is opening new possibilities for networking. In particular, opportunistic communication embodies a feasible solution for environments with scarce or costly infrastructure-based connectivity. In this context we provide a delay-tolerant solution that provides service opportunistic...
Of late, an easy access to the Web 2.0 applications through the hand-held mobile devices has provided the consumers with the opportunity to express opinions on their invoked services conveniently. These opinions, also known as the Internet word of mouth, often impact a potential consumer's service selection notably in service rich urban terrains. Access to these opinions involves tariffs since they...
Cellular networks are currently facing significant challenges as mobile Internet access adoption continues to grow over the subscriber base. The challenge that network operators are facing is that Internet data traffic consumes considerably more resources than voice calls, necessitating in that respect significant capacity enhancements. Further, this rise in system utilization has caused a considerable...
In this paper, we introduce distributed caching of videos at the base-stations of the Radio Access Network (RAN) as a way to reduce the need to bring requested videos from Internet CDNs, thereby reducing backhaul transmission, improving video quality of experience — delay and video stalling — and increasing overall network capacity to support more number of simultaneous video requests. Unlike Internet...
In recent years, Internet of Things (IoT) has become the hottest issues of Future Internet. It is the most important concept of Future Internet for providing a common global IT Platform to combine seamless networks and networked things. However, there is a lack of common fabric for integrating IoT with current Internet. That results the service providers and operators have no definite specification...
The ever growing number of Internet subscribers through mobile devices has led to the requirement of better mobility management protocols. Mobile IP version 6 (MIPv6) by IETF supports IPv6 mobility by providing mobile nodes with uninterrupted Internet connectivity and services. MIPv6 provides network layer mobility but handoff from one network to another network causes handoff latency. Due to this...
Mobile Ad-hoc Networks (MANETs) exhibit unpredictable topology with heterogeneous node contact rates, high mobility and limited information. When dealing with such challenging environments, the mobility model has a key role in testing the performance and proving the expected behavior of routing algorithms. While synthetic mobility models have been largely used to measure quantitative aspects of routing...
Deployment of Broadband Internet is currently one of the most important global issues. Plans for developing agendas are very ambitious but implementation is not as expected. In this paper authors analyse broadband growth and its limitation factors, delays and gaps. Using logistic growth function, the growth limit, delay and gap for Serbia is calculated in reference to the average of EU countries....
Network mobility support is a matter of great concern in mobile IPv6. The authors have proposed an innovative scheme for handling the delay due to handover. The proposed scheme aims to free Mobility Anchor Point (MAP) from overload, while guaranteeing low latency due to handoff.
In IP-based wireless/mobile networks, mobility support is one of the most critical issues. Hierarchical Mobile IPv6 (HMIPv6) was proposed by Internet Engineering Task Force (IETF) to mitigate the high signaling overhead in Mobile IPv6 networks when mobile nodes (MNs) perform frequent hand-offs. Although the standardization process of the HMIPv6 specification has been almost completed in IETF, there...
The rapidly growing interest in untethered Internet connections, especially in terms of WLAN and 3G/4G mobile connections, calls for intelligent session management: a mobile device should be able to provide a reasonable end-user experience despite location changes, disconnection periods and, not least, handovers. As part of an effort to develop a SCTP-based session management framework that meets...
Infrastructure networks like Internet have some coverage gaps (e.g. rural areas) where no service connectivity is provided. Cellular networks could be used in alternative but they usually associate their services with a usage cost. Nowadays, the growing number of mobile devices equipped with a wireless interface and the end-user trend to shift toward wireless technology has opened new possibilities...
High availability WAN connectivity has traditionally been implemented with a single service provider building links with high quality hardware, redundancy, and SLA guarantees. We have studied and implemented an alternative, a MIP-based overlay approach that is both economical and can be deployed in present-day Internet. In this paper, we investigate the performance of our implementation of a Redundant...
This The duration of a standard MIPv6 (Mobile IPv6)handover process is relatively long for many real-time sensitive applications. Many earlier proposed solutions of this problem aim on reducing the duration of the address registration and configuration processes during a handover. There are only few paper intended to shorten the DAD (Duplicate Address Detection) process in a MIPv6 handover. In this...
Next Generation Networks (NGN) are envisioned to be fully Internet Protocol (IP) based so that users can experience high quality and ubiquitous communication. In order to realize this, Internet Engineering Task Force (IETF) is taking advantage of Mobile Internet Protocol version 6 (MIPv6) because it has more suitable features than MIPv4. However, MIPv6 is not widely deployed due to handoff latency...
Vehicular Delay-Tolerant Networks (VDTNs) aim to provide non-real time services and applications, such as electronic mail or file transfer, in environments with sparse and intermittent connectivity, variable delays, or where an end-to-end connection may not exist. Gathering contributions from opportunistic and cooperative networks, VDTN tries to generalize the delay-tolerant networks concept and apply...
Mobile IPv6 (MIPv6) was developed by the Internet Engineering Task Force to support the mobility service as wireless technologies have grown and many people are more and more using wireless networks during movements. MIPv6 has long been favored over Mobile IPv4 and it's a major solution to supply mobility services on the Internet and therefore it's proposed for the future of the mobile Internet access...
In order to construct the highway networks, the road tunnels become an inevitable deign to accommodate physical environment elements (e.g., mountains and rivers) in the world. For the recent constructed tunnels, the communication system within the tunnel is planed and designed ahead of time. However, the cost to build and maintain a complete communication system for existing tunnels may not be a cost...
