This paper studies gradient routing with two-hop information for industrial wireless sensor network to enhance real-time performance with energy efficiency. The two-hop information routing is adopted as that in two-hop velocity based routing and the proposed routing algorithm is based on the number of hops to sink instead of distance. Furthermore, an acknowledgement control scheme reduces energy consumption...
The network management plays an important role in Wireless Sensor Networks WSNs, to control both the sleep and the wake times of the nodes to make data transmissions in an energy-efficient way, thus prolonging network lifetime. In this paper, we propose an innovative approach to control the uptime of the nodes of an Industrial WSN using a fuzzy based algorithm. In a scenario of process control is...
The paper deals with the production process control in dynamic shop floor with unforeseen inside and outside disturbances occurring frequently. The emerging wireless sensor network technology is proposed to implement autonomous shop floor control that can improve shop floor performance by distributed and flexible coping of complexity and dynamics. A wireless sensor network based control structure...
In this paper, an association method for IWSNs (industrial wireless sensor networks) using dynamic hysteresis is proposed. The energy consumption of the nodes can be effectively managed by a decrease in the response packets of the neighbors under the joining requests of the mobile nodes. However, static hysteresis causes a decrease in the joining period for preventing the ping-pong phenomenon. In...
In this paper, we propose a distributed traffic-aware routing system for wireless sensor networks with multiple sinks. In multisink networks, traffic moving toward one sink may congest that moving toward others. The algorithm presented here considers the traffic of surrounding neighbors before jumping to any sink. We accomplish this by building, for each single sink, a gradient field and using gradient...
A growing trend in the automation industry is to use wireless technologies to reduce cable cost, deployment time, unlocking of stranded information in previously deployed devices, and enabling wireless control applications. Despite a huge research effort in the area of wireless sensor networks (WSNs), there are several issues that have not been addressed properly such that WSNs can be adopted properly...
In Europe, the manufacturing sector represents nearly the 22% of the GDP. Since the beginning of the European Technology Platform MANUFUTURE, Service Oriented Architecture have become the de facto in the industrial informatics research community. In most cases, SOA is implemented by using Web Service technology based on RESTful services or WS-∗ standards. Several publications have shown the advantages...
Future networked embedded systems (NES) will be complex systems deeply integrated in the environment that they monitor. They will have to react to both user and environmental events, and this may require modifying their structure to handle the changing situations. For a number of domains, such adaptation will need to take place in real-time, introducing a hard problem that will require novel and paradigmatic...
