Differential transmission for amplifyand-forward cooperative communications
- Table of Integrals, Series, and Products
, 2005
"... Abstract—In this letter, we propose a differential amplify-andforward (AF) transmission scheme for a two-user cooperative communications system. By efficiently combining signals from both direct and relay links, the proposed scheme provides superior performance compared to those of direct transmissi ..."

Cooperative diversity in wireless networks: efficient protocols and outage behavior
- IEEE TRANS. INFORM. THEORY
, 2004
"... We develop and analyze low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks. The underlying techniques exploit space diversity available through cooperating terminals’ relaying signals for one another. We outline several strategies ..."

Analyzing amplifyand-forward and decode-and-forward cooperative strategies in Wyner’s channel model
- in Proc. IEEE WCNC
"... Abstract—The benefits of Amplify-and-Forward (AF) and Decode-and-Forward (DF) cooperative relay for secure commu-nication are investigated within Wyner’s wiretap channel. We characterize the secrecy rate when source, destination, relay and eavesdropper all use single antenna and the channel conditio ..."

Ant Colony System: A cooperative learning approach to the traveling salesman problem
- IEEE TRANSACTIONS ON EVOLUTIONARY COMPUTATION
, 1997
"... This paper introduces the ant colony system (ACS), a distributed algorithm that is applied to the traveling salesman problem (TSP). In the ACS, a set of cooperating agents called ants cooperate to find good solutions to TSP’s. Ants cooperate using an indirect form of communication mediated by a pher ..."

Basic concepts and taxonomy of dependable and secure computing
- IEEE TDSC
, 2004
"... This paper gives the main definitions relating to dependability, a generic concept including as special case such attributes as reliability, availability, safety, integrity, maintainability, etc. Security brings in concerns for confidentiality, in addition to availability and integrity. Basic defin ..."

Efficient Software-Based Fault Isolation
, 1993
"... One way to provide fault isolation among cooperating software modules is to place each in its own address space. However, for tightly-coupled modules, this solution incurs prohibitive context switch overhead, In this paper, we present a software approach to implementing fault isolation within a sing ..."
