We study a problem in which a single sensor is scheduled to observe sites periodically, motivated by applications in which the goal is to maintain up-to-date readings for all the observed sites. In the existing literature, it is typically assumed that the time for a sensor switching from one site to another is negligible. This may not be the case in applications such as camera surveillance of a border,...
The goal of a tactical military network is to provide information superiority over an opposing force. This information superiority increases mission tempo if the information can be used to make correct decisions within time constraints. To achieve this goal, a sufficient amount of information must be received with a required quality. The information quality implicitly accounts for the level of security...
Cooperative caching in MANETS and forwarding data items through mobile nodes in Delay Tolerant Networks are two important methods for improving performance and providing connectivity in mobile tactical networks. In this paper we present the challenges of securing cooperative caching the DTN systems. Our security solution is based on MML-IPSec. The main challenge of this system is key distribution...
