By delaying the data request for a while before resorting to the cellular network, the vehicular user can utilize the opportunistically available WiFi connections during the delay to serve its request An important question here is: how long should the user wait...
The communication network is a main component of digital substation, its performance has a great influence on the security and reliability of power system. Considering IEC61850, by real time digital simulator (RTDS), the merging units and intelligent switches in the digital substation communication network simulation platform are established. Meanwhile, according to the main wire in 220kV substation,...
In this paper, we propose a novel Intrusion Detection System (IDS), Court-like Cluster-based IDS (CCIDS), to secure routing protocols in Mobile Ad Hoc Networks (MANETs). After the network is divided into one-hop clusters, each of these clusters performs similar functions as a court in real-life, such as accusation, investigation and defence. We show that court like IDS is effective in many aspects,...
