Wireless sensor nodes have been provided with some parts in order to receive audio and video like camera and microphone which were called wireless multimedia sensor networks (WMSN). In this paper, we proposed a new QoS-based routing protocol for WMSN. This protocol is routed according to quality of service (QoS) requirements for each data packet. With each packet, protocol tries to perform rout...

This paper offers a novel approach to the evaluation of provenance blockchain security and reliability using analytical methods for assessing system availability against malicious miner DoS attacks. In particular, we present analysis LightWeight Mining (LWM) protocol securing data provenance. Our shows its ability protect We use digital signatures prove integrity non-repudiation messages passin...

This paper addresses the study of a linkage network of biserial queues linked to a common server with a multistage flowshop scheduling system having ‘m’ machines or servers in series under fuzzy environment. Waiting lines or queues are commonly occurred both in everyday life and in a variety of business and industrial situations. Also, the flowshop scheduling is an important task when a number ...

We present TRESTLE, an incremental algorithm for probabilistic concept formation in structured domains that builds on prior concept learning research. TRESTLE works by creating a hierarchical categorization tree that can be used to predict missing attribute values and cluster sets of examples into conceptually meaningful groups. It is able to update its knowledge by partially matching novel str...

Output Queuing (OQ) and Input Queuing (IQ) are the two basic queuing strategies implemented in routers. IQ has been identified as the simplest and the most scalable. However, IQ achieves only 58.6% throughput due to the Head Of Line (HOL) blocking effect. The Virtual Output Queuing (VOQ) strategy is a proffered solution to the HOL blocking. It has been shown that VOQ can achieve a 100% throughp...

Queuing theory is the branch of Operations research in applied mathematics and deals with phenomenon of waiting lines. Queuing theory is concerned with the mathematical modeling and analysis of systems which provides service to random demands. In this paper, we have focused the applications of queuing theory in the field of healthcare (hospital) i.e. one of the biological paradigm. The health s...

Many measurement studies showed that network traffic usually exhibits self-similar nature, meanwhile, wireless fading channels lead to the time-variant service rates of network nodes. Compared with classical queuing systems with Markov sources or constant service rates, the queuing system with self-similar input in a wireless fading channel is more complicated, and it is very difficult to obtai...

Cell formation problem mainly address how machines should be grouped and parts be processed in cells. In dynamic environments, product mix and demand change in each period of the planning horizon. Incorporating such assumption in the model increases flexibility of the system to meet customer’s requirements. In this model, to ensure the reliability of the system in presence of unreliable machine...

The standardization bodies have defined the Dynamic Generic Cell Rate Algorithm (DGCRA) as the Conformance Definition for ABR. This algorithm may be implemented in the Usage Parameter Control (UPC) for policing. In this paper we describe an equivalent queuing model of the DGRCA and we solve this model using a matrix analytic approach. The analytical results are validated by simulation.
