Inter-process communication (IPC) is one of the crucial aspects of every microkernel. The message-passing interface (MPI) is a specification between different processes, which is used for communication amongst processes. Message Passing Interface Chameleon (MPICH) is the portable implementation of message passing interface. This paper delineates the comparison between IPC, MPI and MPICH in terms of...
This paper deals with the design principles and implementation of a reconfigurable real-time software platform designed for data exchange between software modules of unmanned underwater and surface vehicles. The aim of developing a new robotic platform was the realization of a light-weight OS-independent library that allows integrating AUVs, ROVs and surface vehicles to a single computing cluster...
We propose a synchronized playback method for the real-time synchronization of the playback position of streaming media to multiple clients from a streaming server. The playback-related information that is used in this synchronized playback method comprises the current time and the playback position, and the server transmits the playback position and the current time to the client. The client can...
This paper presents a mechanism to manage a dynamic group in an automatic way for sending Group IM (instant message) based on presence service in IMS system. Presence technology is gaining significant interest nowadays. It can show the user's presence information in real time. Presence based services are driving new business opportunities and changing every aspect of our daily life, especially in...
Web-content publishing is a service that is mainly provided by traditional client-server architecture. However, traditional approach requires much computer and network resources and therefore is relatively expensive. There are methods to publish web-content directly from users own computers. But in these approaches users have to keep their computers switched on continuously to publish for 24 hours...
Password-based authenticated group key exchange protocols allow group users to jointly share a session key based on a human-memorizable password. In this paper, we present an undetectable online dictionary attack on N-EKE-D, a recent provably secure protocol designed to explicitly resist this type of attack. Thus, our result contradicts the design goal. We also give a simple attack on the key indistinguishability...
