We propose new authentication protocols to support fast handover in IEEE 802.11-based wireless mesh networks. The authentication server does not need to be involved in the handover authentication process. Instead, mesh access points directly authenticate mobile clients using tickets, avoiding multi-hop wireless communications in order to minimize the authentication delay. Numerical analysis and simulation...
A Delay Tolerant Network (DTN) is a network where nodes can be highly mobile, with long message delay times, forming dynamic and fragmented networks. Conventional centralised network security mechanisms are unsuitable in such networks, therefore distributed security solutions are more desirable in DTN implementations. Establishing effective trust in distributed systems with no centralised Public Key...
