The availability of small, low-cost, battery operated devices capable of sensing, performing simple processing and transmitting data via wireless communications have the potential to revolutionize traditional monitoring applications. Wireless networks composed of autonomous sensor nodes enable ubiquitous monitoring tasks from environmental control of office buildings to the detection of forest ...

The main contribution of this paper is twofold. First, we present an appropriate schedulability analysis, based on response time analysis, for supporting fault-tolerant hard real-time systems. We consider systems that make use of error-recovery techniques to carry out fault tolerance. Second, we propose a new priority assignment algorithm which can be used, together with the schedulability anal...

In this paper, we investigate the quality of several linear-time schedulability tests for preemptive and non-preemptive fixed-priority scheduling of uniprocessor systems. The metric used to assess the quality of these tests is the resource augmentation bound commonly known as the processor speedup factor. The speedup factor of a schedulability test corresponds to the smallest factor by which th...

This paper introduces a new packet scheduling algorithm for multi-media traffic. The proposed modified priority queuing (MPQ) packet scheduling algorithm, realizing the high priority traffic service employs exponential distributions with the higher averages respectively, secures the reduction in the mean waiting time regarding the high priority traffic sensitive to delay. Thus, we could meet th...

In this paper we introduce a dynamic vehicle routing problem in which there are multiple vehicles and multiple priority classes of service demands. Service demands of each priority class arrive in the environment randomly over time and require a random amount of on-site service that is characteristic of the class. To service a demand, one of the vehicles must travel to the demand location and r...

A wireless ad-hoc network is a self-organized wireless network without fixed or backbone infrastructure. All nodes have routing capability and use peer-to-peer packet transmission or forward packets to other node using multi hop communication. Now days mobile ad-hoc networks are being used for different applications and traffics, so it require quality of service (QoS) support in routing protoco...

Priority Sector Lending (PSL) is a financial inclusion strategy that encourages banks to support vital industries for stimulating economic expansion. This study aims analyse how different service quality parameters affect customer satisfaction. The 339 people who used PSL agricultural and educational loans provided responses. Path analysis using Structural Equation Modelling (SEM) was assess th...
