Distributed processing is an essential part of collaborative computing techniques over ad-hoc networks. In this paper, a generalized particle swarm optimization (PSO) model for communication networks is introduced. A modified version of PSO, called trained PSO (TPSO), consisting of distributed particles that are adapted to reduce traffic and computational overhead of the optimization process is...

The retail industry plays an important role in the economic development of the world. The Collaborative Planning, Forecasting and Replenishment (CPFR) solution can coordinate the business process between the retailers and manufacturers in the retail supply chain and got its applications in many world-renowned retailers around the world. In this paper, CPFR coordination process and its applicati...

For people to entrust their private information to modern collaborative tools, they will want some assurance of the extent to which this information will be protected. Accurately measuring the amount of privacy lost by different collaborative technologies is a critical step in providing such assurances. Unfortunately, the identification of intuitive and useful metrics for privacy loss has prove...

Cognitive Radio (CR) is a novel technology that permits secondary users (SUs) to transmit alongside primary users (PUs). PUs retain transparent communications whereas SUs perform spectrum sensing and adaptive transmission to avoid collisions. Ultra-wideband sensing is of primary importance for SU to sense and access opportunistically several bands at a time. Reliable detection in wide geographi...
