In this paper, we present our work on designing a communication network for orbit access in future lunar exploration missions. We first discuss the characteristics of space communication for lunar missions that influence the network design, and then address some highlighted issues in the system framework which adopts both the delay-tolerant network (DTN)-based technologies and the mobile ad hoc network...
The key contribution of the work herein described is an integrated network service architecture for airborne networks (ANs), wherein a set of robust and auto-configurable network service mechanisms are designed to handle network dynamics and bandwidth constraints in AN environments. Instead of covering all possible network services, address configuration and name resolution are addressed in this paper...
Existing commercial database security products cannot guarantee to provide the same level database security in Mobile Ad-Hoc Networks (MANET) as in wired networks. In this paper, we presented a secure MANET database system that uses metadata and context information for database access control. First, we designed and implemented a context-based security model that uses context factors, such as location...
