The provision of Internet connectivity for a vehicle anywhere anytime is an essential element to realize the vision of Connected Car. However, we observe that the current vehicular network technologies mainly focus on single-hop communications having limited coverage for the Internet connectivity. Accordingly, in order to support the always Internet connectivity, multi-hop routing that can cover wider...
We propose the Floating Ground Architecture (FGA) for network mobility and ad hoc network convergence. Various factors, including excessive dependence on intelligence in the fixed network, result in the Internet having a de facto logical boundary one hop from the fixed network. To reduce these dependencies, FGA introduces a new logical layer, called Floating Ground, between the fixed network infrastructure...
Internet of Things is an evolution from computer networks to a network of interconnected objects such as books, cars, sensors, etc… In recent years, interest in the applications of Wireless Body Area Networks (BANs), have grown significantly and this opens up an important number of challenges such as mobility management. Locator/Id Split Protocol (LISP) deals with the traditional IP problems like...
Named data networking (NDN) shifts today's host-centric Internet architecture to a new data-centric network architecture. This well suits the increasingly mobile and information-intensive applications that dominate today's Internet. NDN allows routers to cache named content, leading to a significant improvement of content retrieval which, however, opens a door for many new attacks. In this work, we...
Rural networking connectivity is a very dynamic and attractive research field. Nowadays big IT companies like Google and Facebook are working to help connect all these rural disconnected people to Internet. Our research work is another effort in this direction. We are building a new solution based on previously tested ideas that can bring no real-time Internet connectivity to rural users using Delay/Disruption...
Named Data Networking (NDN) is a novel architecture expected to overcome limitations of the current Internet. User mobility is one of the most relevant limitations to be addressed. NDN supports consumer mobility by design but fails to offer the same level of support for producer mobility. Existing approaches to extend NDN are host-centric, which conflicts with NDN principles, and provide limited support...
The content centric network (CCN) is the new communication paradigm conceived for the future Internet. The basic idea of CCN is to use content names as addresses instead of IP-based host addresses. Video streaming services like YouTube represent the most important part of the internet traffic. Recently, the impact of mobility on video streaming over multi-hop wireless networks has become the real...
This paper presents a detailed description of content delivery techniques used in the proposed MobilityFirst (MF) clean-slate future Internet architecture now under development. The MF architecture addresses the requirements of mobile content delivery using the following basic design elements: (1). mapping of human readable names to “flat” globally unique identifiers (GUID's) which are used as the...
The mobile adhoc networks have become a major component of the future network development due to their ease of deployment, self configurability, flexibility and independence on any existing network infrastructure Mobile ad-hoc network have the attributes such as wireless connection, continuously changing topology, distributed operation and ease of deployment. We present a design space analysis of...
Designing an efficient micro-mobility scheme for network mobility (NEMO) is an important issue. The Micro-NEMO is a well known protocol for micro mobility in NEMO. It has significantly lower signaling overhead and handoff latency. But, it suffers from single point failure problem. In this paper, we propose micro-NEMO++, an extension of micro-NEMO protocol, to eliminate the single point failure problem...
Network mobility at continental scales requires transitioning between a collection of provider networks to maintain connectivity while traveling. Ideally, the transitions between networks occur transparently to end users therefore placing the burden of redirecting traffic on the inter-domain routing infrastructure. Performing inter-domain routing in mobile scenarios has been discouraged since BGP...
In a Wireless Sensor Networks (WSN), there are normally one or several sensor nodes working as Access Points (AP), which are able to provide a relay for other sensors to an external Internet connection. Since WSNs are resource-constrained, the selection of APs is very crucial in economizing power usage. In this paper, we study the optimal selection of APs to maximize the WSN lifetime. This issue is...
This paper examines en-route caching of personal content for mobile users with intermittent connectivity. Our goal is to optimize in-network caching in order to reduce the number of retrieval attempts for each content request. Therefore, we design two distributed caching techniques: in last router caching, a router caches a file only when it detects that the end user has disconnected; in price based...
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...
In mobile ad hoc networks (MANETs) where there exist multiple Internet gateways, performing load balancing among available gateways is vital in order to take full advantage of the network capacity and improve the performance. However, performing load balancing in a wireless environment is very challenging due to the inherently interfering and unreliable nature that characterize wireless communication...
MANET (Mobile Ad Hoc Networks) is turning to be the recommended way to interconnect mobile nodes (MNs) to Internet when they move away from networks structures. The Mobile IP agents used to permit MNs IP mobility may announce their presence either using a proactive or a reactive discovery approach, but when MNs handover between different MANET sub-networks, ongoing communications may become interrupted...
Integrating nodes in a MANET to the Internet require either a connection to the Internet or they can connect to the Internet through the Internet gateways or servers. For the second case a node in a MANET has to find out the gateway or server to connect to the fixed nodes in the Internet. End to end packet delay and throughput are strongly dependent on the time needed to discover the gateways. A source...
Networked devices are often equipped with multiple interfaces. Legacy routing and transport protocols only support the transport of data over a single interface resp. paths. This tutorial discusses extensions for IP and TCP in order to support multiple interfaces. Multihoming and mobility management allow the simultaneous usage of interfaces by independent application data flows, while multipath transport...
Energy costs for data centers are a significant part of the overall expenses for their operation. With a reduction of these and associated costs, huge savings can be achieved. This paper describes a way to reduce the energy costs for data centers. The general idea behind our solution is very simple. Instead of routing the information required for any service interaction to and from the data center...
We present a novel mobility management scheme for seamless Internet access in urban vehicular scenarios. The scheme is based on Proxy Mobile IPv6 and Host Identity Protocol, and allows users to handoff within and across different administrative domains. We consider two types of nodes: legacy nodes with no mobility support (e.g., end devices that depend on the vehicle's mobile router for the support...
