Today’s location-sensitive service relies on user’s mobile device to determine the current location. This allows malicioususers to access a restricted resource or provide bogus alibis by cheating on their locations. To address this issue, we propose A Privacy -Preserving Location proof Updating System (APPLAUS) in which colocated Bluetooth enabled mobile devices mutually generate location proofs […]
Correlated flooding in low-duty-cycle wireless sensor networks
Although existing flooding protocols can provide efficient and reliable communication in wireless sensor networks on some level, further performance improvement has been hampered by the assumption of link independence, which requires costly acknowledgments (ACKs) from every receiver. Flooding is a network-layer protocol that delivers a message from one node to all the other nodes inside […]
Distributed management for load balancing in content delivery networks
In this paper, we face the challenging issue of defining and implementing an effective law for load balancing in Content Delivery Networks (CDNs). We base our proposal on a formal study of a CDN system, carried out through the exploitation of a fluid flow model characterization of the network of servers. Starting from such characterization, […]
