The interoperability between various automation systems is considered as one of the major character of future automation systems. Service-oriented Architecture is a possible interoperability enabler between legacy and future automation systems. In order to prove the interoperability between those systems, a verification framework is essential. This paper proposes a configurable cloud-based validation...
A distributed location detection problem in wireless sensor networks (WSNs) with M anchors and one node is considered in this paper. In the presence of the transmitting node at a known location, each anchor receives a noisy signal in the presence of node. In the absence of the node, the anchors receive only noise. Each anchor makes a decision as to whether the node is present or not by using a Neyman-Pearson...
This paper is following the development of real-time applications for marine operations focusing on modern modeling and simulation methods and presents a common framework model for multi-purpose underwater sensors used for offshore exploration. It's addressing deployment challenges of underwater sensor networks “safe-nets” using remote operated vehicles (ROV).
In wireless sensor network (WSN) deployments, Receiver-side Collision Detection (RCD) has been proposed for speeding up collaborative feedback collection from a single hop neighborhood. Using RCD, an initiator node can query the existence of a predicate P in its neighborhood in constant time by making all P-positive nodes answer simultaneously. Despite the collisions, the initiator is still able to...
The use of simulation tools in the development of new Wireless Sensor Networks protocols and applications should be accompanied by minimisation of redundant code and work, making it possible to seamlessly run the same code on simulated and real platforms. This work proposes an architecture for a WSN testing platform that integrates simulation tools in an application-transparent way. The platform will...
Developing applications and protocols for wireless sensor networks is a time consuming and error prone task, which possibly includes many iterations of implementation and testing. While simulations will probably not replace testbed experiments completely, they are a time efficient tool for rapid prototyping of sensor networks. Writing code and testing an application is often done using a different...
Development of wireless sensor networks deals with several difficulties, including time, cost and complexity of testing. In particular, indoor environment poses several specific constraints on radio wave propagation due to density of obstacles. This must be taken into account if we want to discover and validate network configurations and communication paths. We suggest the use of virtual worlds, exploiting...
Routing protocols for large wireless networks must address the challenges of reliable packet delivery at increasingly large scales and with highly limited resources. Attempts to reduce routing state can result in undesirable worst-case routing performance, as measured by stretch, which is the ratio of the hop count of the selected path to that of the optimal path. We present a new routing protocol,...
Wireless sensor networks greatly benefit from simulation before deployment, since some of these networks may contain thousands of nodes. The new challenges compared to traditional computer networks led to several approaches for network simulation, namely SENSE - Sensor Network Emulator and Simulator. However this approach presents a limited user interface, namely based on text, forcing users to have...
