A centralized feedback control model for resource management in wireless networks

In a wireless environment, guaranteeing QoS is challenging because applications at multiple devices share the same limited radio bandwidth. In this paper we introduce and study a resource management model for centralized wireless networks, using feedback control theory. Before applying in practice, the proposed model is evaluated using the well-known 20-sim dynamic system simulator. The experimental results show that flexible and efficient resource allocation can be achieved for a variety of system parameters and WLAN scenarios; however, care should be taken in setting the control parameters and coefficients

Onion routing in deterministic delay tolerant networks

Aquest volum de Lecture notes in computer science, amb el títol Foundations and Practice of Security, recull les actes al 8th International Symposium on Foundations & Practice of Security que va tenir lloc a Clermont-Ferrand (France), del 16 al 28 d'octubre de 2015Deterministic DTNs are networks where the behavior is known in advance or where a repetitive action occurs over time like in public transportation networks. This work proposes the application of an onion routing approach to deterministic DTNs to achieve anonymous communications. We show how the prior stage of path selection in onion routing can be achieved using the information provided by deterministic networks
