We address the problem of selective jamming attacks in wireless networks. In these attacks, the adversary selectively targets specific packets of "high" importance by exploiting his knowledge on the implementation details of network protocols at various layers of the protocol stack. We illustrate the impact of selective jamming on the network performance by illustrating various selective...
We present a formal model for modeling and reasoning about security protocols. Our model extends standard, inductive, trace-based, symbolic approaches with a formalization of physical properties of the environment, namely communication, location, and time. In particular, communication is subject to physical constraints, for example, message transmission takes time determined by the communication medium...
The main objective of this paper is to show new possibilities of wireless communication for mobile robotic and industrial units in the real time. The means of using wireless communication networks based on parallel processing and data transfer for various network topologies are discussed here. We have been focusing our research on ultra low power communication chips based on frequency 2.4 GHz. Furthermore...
Multicasting has not been widely adopted until now, due to lack of receiver or end user (EU) access control. We have developed the Internet group management protocol with access control (IGMP-AC), an extended version of IGMPv3, which provides EU access control by incorporating the AAA framework into the existing multicast service model. Furthermore, IGMP-AC works as an extensible authentication protocol...
Cooperation among nodes is vital in wireless networks since in such networks nodes depend on each other for routing packets. However, cooperation in such operations consumes nodes recourses such as battery and bandwidth. Therefore, it is necessary to design incentive mechanisms to enforce nodes to forward packets when the source and destination of the packet are other nodes. We study routing in wireless...
