Multicast communication is becoming the basis for a growing number of applications. Therefore, securing multicast communication is a strategic requirement for effective deployment of large scale business multi-party applications. One of the main issues in securing multicast communication is the source authentication service. We address the multicast stream authentication problem when the communication...
The paper discusses the cooperation method among multiple agents in 3D space based on intention recognition. It is assumed that an observer observes multiple moving objects that are its company and the enemy. The purpose of our work is to help the observer to make cooperation decision efficiently. Due to the distortions the perspective brings, cooperating in 3D space is difficult. To contact agents...
In this paper, we propose a robust STBC transmission scheme to combat the timing synchronization errors over frequency-selective multiple-access channels. First, the equivalent channel model in the presence of timing synchronization errors is derived and we find that the synchronization errors result in an equivalent channel model with larger number of correlated channel taps. Based on this correlated...
In conventional optical data transmission schemes, electrical filters and/or optical filters are used to improve the quality of system performance. In this paper, improved design of dense wavelength division multiplexing (DWDM) optical systems is achieved by using a selective electrical filter assignment method. The methodology objective is to optimize system design and mitigate the effects of fiber...
