In real-time multicast, delay and inter-destination delay variation of group members are bounded above by a value. The problem is known as Delay and Delay Variation Bounded Multicast Tree (DVBMT), which is proven to be NP-complete. In this paper, we propose a directional approach (DCS) for core selection and tree generation satisfying delay and inter-destination delay variation constraints. After...
The sense of agency (SoA) describes the feeling of being the author and in control of one's movements. It is closely linked to automated aspects of sensorimotor control and understood to depend on one's ability to monitor the details of one's movements. As such SoA has been argued to be a critical component of self-awareness in general and contribute to presence in virtual reality environments in...
The utilization of orthogonal variable spreading factor (OVSF) in CDMA networks limits the number of calls which can be handled due to their orthogonal nature. Therefore, a multi code assignment scheme is required which can utilize efficiently the scattered vacant code over the period of time. This paper describes a scheme which is the extension of FFSP scheme. The multi code flexible fixed set portioning...
There are several research projects ongoing to apply cloud computing to industrial systems. The main focus of them is real-time performance of virtual machines (VMs) since it is important to guarantee a time-critical feature of industrial systems. However, there is another important issue that how much computing resource (CPU, memory, etc.) should be allocated to each VM which runs processes of an...
This paper presents the design and hardware implementation of two-stage lumped-element All-Pass Network for group delay engineering. It is designed for 700 MHz band that is assigned for Software Defined Radio and Cognitive Radio applications. Both positive and negative group delay variation is obtained across the band with slope +5.3 ns/GHz and −4.7 ns/GHz. The application of real-time frequency discriminator...
Real-time system depends upon the temporal attributes, therefore scheduler should schedule the tasks properly so that the system is reliable. Scheduling real time task, involves parameters such as job's priority, computing resource availability, estimated execution time, etc…, but out of this cache management is very important issue which may have serious impact on execution time of the task. Cache...
Usage of multimedia communication in everyday life has seen a remarkable growth. Vast in Bandwidth demand often result in lower network performance and reduced quality of user experience during congestion. In this paper, we will address congestion control problem while providing quality of service (QOS) of delay for inelastic flows like video streaming, IPTV, etc. First, we propose an extension of...
Remote control and monitoring are very necessary in decentralized manufacturing environments. This is evidenced by todaypsilas distributed shop floors where agility and responsiveness are required to maintain high productivity and flexibility. However, there exists a lack of an effective system architecture that integrates remote condition monitoring and control of automated equipment; that give much...
