A delay/disruption tolerant network (DTN) architecture where a “store-carry-forward” strategy is adopted for data transmissions can be utilized in vehicular ad hoc networks (VANETs). The key point of routing in DTN-enabled VANETs is to choose the best node and determine the best time to forward messages. Time-space graph models provide an idea of converting the dynamic routing problems into static...
With the further development and utilization of space resource, space communications nowadays are increasingly becoming irreplaceable networking technologies for highresolution earth observation, satellite navigation and deep space exploration where big data is produced. This has created great challenges in ensuring the security and reliability of some sensitive data. In order to solve some problems...
Intrusion Detection System (IDS) is considered as one of the most effective security mechanisms in wireless networks. However, nodes which are used to monitor the network abnormal behaviors will carry out amount of overhead and degrade network performance. In this paper, we propose a monitor node selection algorithm based on mutual information to solve the above issue. In the algorithm, we consider...
