—User-generated content (UGC) is emerging as one of the dominate forms in global media industry. However, the efficient delivery of UGC faces with massive technical challenges due to its long-tail nature. Content delivery networks (CDN) based systems are considered as the potential solutions to deliver UGC. But none of the existing CDN based solutions can(More)
—Trust and security have been considered as built-in properties for future Internet architecture. Leveraging the concept of named content in recently proposed information centric network, we propose a name-based trust and security protection mechanism. Our scheme is built with identity-based cryptography (IBC), where the identity of a user or device can act(More)
Asymmetric links are common in wireless networks for a variety of physical, logical, operational, and legal considerations. An asymmetric link supports uni-directional communication between a pair of mobile stations and requires a set of relay stations for the transmission of packets in the other direction. We introduce a MAC layer protocol for wireless(More)
—Information-centric networking (ICN) proposes to redesign the Internet by replacing its host centric design with an information centric one, by establishing communication at the naming level, with the receiver side acting as the driving force behind content delivery. Such design promises great advantages for the delivery of content to and from mobile(More)
In many instances, an ad hoc network consists of nodes with different hardware and software capabilities as well as power limitations. This is the case of ad hoc grids where devices such as desktops, laptops, robots, palmtops, sensors, and actuators collaborate to solve computational problems. In such a heterogeneous environment, the nodes have various(More)
We introduce AsyMAC, a MAC layer protocol for wireless networks with asym-metric links and study a protocol stack consisting of AsyMAC and the A 4 LP routing protocol. The two protocols are able to maintain connectivity where the standard IEEE 802.11 MAC protocol coupled with either AODV or OLSR routing protocols may loose connectivity. A comparative study(More)
—Information-Centric Networking (ICN) architec-tures aim to replace current host-centric IP architecture with an information-centric one for efficient, secure, and reliable dissemination of information. ICN is built on several salient principles such as publish and subscribe paradigm, named content, in-network caching, and security over atomic information(More)
User-generated content (UGC) has become one of the dominant media formats. However, current approach to distribute UGC adds two middlemen (e.g., content aggregator and content distributor) in the value chain, resulting in a higher cost for media consumers. We have proposed a new model for content providers to request content-distribution-as-a-service(More)
—Information-centric networking (ICN) aims to achieve efficient, secure, and reliable dissemination of information in contrast to host-centric IP architecture. This paper presents a case for ICN based home network (homenet). Current IETF proposal for homenets is based on IPv6 which inherits fundamental problems of IP such as security, mobility, and(More)
—ICN deployment will be based on the grounds of saving CAPEX/OPEX and/or enabling new services. This paper makes a case for the latter leveraging, emerging technologies such as network function virtualization (NFV) and software defined networking (SDN). We propose a framework to enable ICN based service platform as virtualized network functions to enable(More)
