Abstract”
Content services such as content filtering and transcoding adapt contents to meet system requirements, display capacities, or user preferences. Data security in such a framework is an important problem and crucial for many Web applications. In this paper, we propose an approach that addresses data integrity and confidentiality in content adaptation and caching by intermediaries. Our approach permits multiple intermediaries to simultaneously perform content services on different portions of the data. Our protocol supports decent ....etc

Abstract
Some recent studies have shown that cooperative cache can improve the system performance in wireless P2P networkssuch as ad hoc networks and mesh networks. However, all these studies are at a very high level, leaving many design andimplementation issues unanswered. In this paper, we present our design and implementation of cooperative cache in wireless P2Pnetworks, and propose solutions to find the best place to cache the data. We propose a novel asymmetric cooperative cache approach,where the data requests are transmitted to ....etc

Reliable Multi-hop Routing with Cooperative Transmissions in Energy-Constrained Networks
Abstract
We present a novel approach in characterizing theoptimal reliable multi-hop virtual multiple-input single-output(vMISO) routing in ad hoc networks. Under a high node densityregime, we determine the optimal cardinality of the cooperationsets at each hop on a path minimizing the total energy cost pertransmitted bit. Optimal cooperating set cardinality curves arederived, and they can be used to determine the optimal routingstrategy based on ....etc

Cooperative Linux, abbrieviated as coLinux, is software that lets Microsoft Windows cooperate with the Linux kernel to run both in parallel on the same machine. Cooperative Linux utilizes the concept of a Cooperative Virtual Machine (CVM). In contrast to traditional VMs, the CVM shares resources that already exist in the host OS. In traditional (host) VMs, resources are virtualized for every (guest) OS. The CVM gives both OSs complete control of the host machine while the traditional VM sets every guest OS in an unprivileged state to access the ....etc

MAC protocols have been studied under different contexts for decades. In decentralized MAC protocols, transmitter-receiver pairs make independent decisions, which are often sub-optimal due to insufficient knowledge about the communication environment. In this paper, we introduce control-plane cooperation at the MAC layer, where neighboring nodes share control information with transmitter-receiver pairs to aid them in making more informed decisions. This augments conventional cooperation, which sits at the data plane where intermediate nodes hel ....etc

Medium access control (MAC) protocols have been studied under different contexts for decades. In decentralized contexts, transmitter-receiver pairs make independent decisions, which are often suboptimal due to insufficient knowledge about the communication environment. In this paper, we introduce ....etc

COOPERATIVE LINUX

Abstract
Software development for an embedded Linux system in most cases requires a free license of GCC (GNU C/C++ compiler) and accessories. Many developers find it disconcerting that the GNU tools are primarily available for Linux-based PCs. Any attempt to make GCC run under Windows in order to program an embedded Linux system has been fraught with problems until now. The popular Cygwin “ as a Unix/Linux emulation environment under Windows “ is muc ....etc

Employing the novel idea of a co-operative virtual machine(CVM) co-operative linux or colinx can support the kernel of both the Microsoft windows and the linux, to run parallel on the same machine. Unlike in the traditional VMs where every guest is in the unprivileged mode to control the real machine also where the resources are virtualised for every OS, the CVM gives both the OSs complete control of the host machine. Since the system hardware of today is not compatible to deal with two different operating systems at a time, the word co-operati ....etc

Abstract—

Cognitive networks can potentially solve the
problems of spectrum scarcity by accommodating unlicensed
(secondary) users in under-utilized segments of the spectrum.
Spectrum sensing serves as the primary stimulus for a cognitive
