♣ This work was supported by ITRC under grant number T/500/4704 Abstract: The QoS-based multicast routing is an important issue in the next generation of high-speed multimedia networks. In this paper, we propose a novel QoS-based (multiple constraints) multicast routing algorithm based on the evolutionary algorithms. The connectivity matrix of edges(More)
The problem of process scheduling in distributed system is one of the important and challenging area of research in computer engineering. Scheduling in distributed operating system has a important role in overall system performance. Process scheduling in distributed system can be defined as allocating processes to processor so that total execution time will(More)
The bandwidth-delay-constrained least-cost multicast routing is a challenging problem in high-speed multimedia networks. Computing such a constrained Steiner tree is an NP-complete problem. In this paper, we propose a novel QoS-based multicast routing algorithm based on the genetic algorithms (GA). In the proposed method, the degree-based permutation(More)
Concept drift, change in the underlying distribution that data points come from, is an inevitable phenomenon in data streams. Due to increase in the number of data streams’ applications such as network intrusion detection, weather forecasting, and detection of unconventional behavior in financial transactions; numerous researches have recently been(More)
The uncertainty principle says that when elementary quantum systems like photons are used for information transmission, it is impossible in principle to eavesdrop on this media without a high probability of disturbing the transmission in such a way as to be detected. By this way we can make an absolutely secure communication link which can not be threaten(More)

—ATM as a high-speed cell switching technology can support multiple classes of traffic with different quality of service (QoS) requirements and diverse traffic characteristics. A main QoS requirement is the cell loss ratio (CLR). We need an expression for the CLR calculation in ATM networks where the statistical multiplexing is an important factor. The(More)
