The delay sensitive application experiences the problem of meeting the deadline without collision in the low rate wireless sensor network. In sensor networks, every application does not require high packet delivery ratio or high throughput rather it demands the accuracy in delivering the small amount of data. Thus this paper presents the priority-based approach for delay sensitive applications ...

Wireless hybrid networks have become quite popular with the evolution of several devices with multiple networking interfaces. Each of these interfaces (and the associated networks) have significantly different characteristics, hence it is important to understand how best to utilize and operate in the presence of multiple networks. Smartphones are a popular example of devices with multiple netwo...

 It is scientifically challenging to determine the inventory level all through the supply chain in such a way that the desired objectives such as effectiveness and responsiveness of the supply chain system can be obtained. Simulation is a means for solving various problems which cannot be solved by regular exact models such as mathematical ones due to their complexity. The present paper is aime...

background and aim: afterpain is a common phenomenon after vaginal delivery. any factor that causes a delay in the process of uterus sub involution and consequently returning its size to pre-pregnancy status could affect the severity of afterpain. this study aimed to investigate the factors related to afterpain in multiparous women delivered in 17-shahrivar hospital, mashhad, iran.  methods: in...

Mobile Ad hoc Networks (MANET) use anonymous routing protocols that hide node identities and routes from outside observers in order to provide anonymity protection. Existing anonymous routing protocols relay on hop by hop encryption or redundant traffic by generation high cost. The high cost exacerbates the inherent resource constraint problem in MANETs. Existing anonymous routing protocols pro...

In this paper, we propose and analyze a new multicast scheme for delivering on-demand streaming data using UEP (UnEqual Protection) codes. The scheme allows an end user to join only one multicast channel for a data stream at any time to play out the requested data stream from its beginning after a fixed initial playout delay. The scheme tolerates packet loss during transmission, thus significan...

We introduce a novel delay pricing and charging scheme in deadline-based networks to support real-time data delivery. We study the delay performance observed by individual users when different levels of deadline urgency are specified and take a market-based approach to determining a delay price. Our pricing and charging scheme can be used to prevent greedy users from gaining an advantage by spe...

With increasing competition in the business world and the emergence and development of new technologies, many companies have turned to integrated production and distribution for timely production and delivery at the lowest cost of production and distribution and with the least delay in delivery. By increasing human population and the increase in greenhouse gas emissions and industrial waste, in...

The infostations system consists of high speed radios transmitting to very small and discontinuous cells. In this paper we investigate the problem of delivering information in a system where the data rate between the infostations and the fixed network is low compared to the radio rate. This situation is the reverse of the usual wireless network model. We approach this problem assuming that deli...
