Transportation costs for road transport companies may be intensified by rising fuel prices, levies, traffic congestion, etc. Of particular concern to the Mpact group of companies is the long waiting times in the queues at loading and offloading points at three processing mills in the KZN (KwaZulu-Natal) province in South Africa. Following a survey among the drivers who regularly deliver at these sites, recommendations for alleviating the lengthy waiting times are put forward. On the strength of one of these recommendations, namely the innovative use of ICTs, suggestions on how cloud-based technologies may be embraced by the company are explored. In the process, the value added by a cloud-based supply chain, enterprise systems, CRM (Customer Relationship Management) and knowledge management is examined.

Future wireless communications are made up of different wireless technologies. In such a scenario, cognitive and cooperative principles create a promising framework for the interaction of these systems. The opportunistic behavior of cognitive radio (CR) provides an efficient use of radio spectrum and makes wireless network setup easier. However more and more frequently, CR features are exploited by malicious attacks, e.g., denial-of-service (DoS). This paper introduces active radio frequency fingerprinting (RFF) with double application scenario. CRs could encapsulate common-control-channel (CCC) information in an existing channel using active RFF and avoiding any additional or dedicated link. On the other hand, a node inside a network could use the same technique to exchange a public key during the setup of secure communication. Results indicate how the active RFF aims to a valuable technique for cognitive radio manager (CRM) framework facilitating data exchange between CRs without any dedicated channel or additional radio resource.
