CSIRO is using wireless sensor network technology for "tiny agents", deployed as autonomous controllers for individual pieces of electrical load/generation equipment in a distributed energy system. The tiny agent concept is a novel application of wireless sensor networks, providing the benefits of multi-agent systems science in a cheap, mobile, and highly distributable platform. However,...
With the proliferation of wireless broadband technologies and the development of advanced smart phones, the transportation and logistics industry is well poised to leverage the advantages of ubiquitous connectivity to provide more reliable, efficient and responsive services. In particular, in the changing landscapes of supply chain management, the transportation management system (TMS) segment is...
The proliferation of wireless networks on unlicensed communication bands leads to coexisting networks, creating interference problems. In this paper, interference problems for spectrum-agile networks are addressed by allowing the networks to dynamically change channel. For insight into dynamic channel-change strategies, we model the networks as autonomous players in a multistage non-cooperative game-theoretic...
In this work, we propose an analytical framework to derive the performance of Bluetooth (BT) in the presence of an IEEE802.11g interferer. In particular, aiming at improving the performance of BT in the presence of interference still maintaining low the complexity, we propose a selection diversity scheme at the receiver side of the BT system and we exploit the spatial diversity to improve the coexistence...
Current research on pervasive systems envisions a world where computation is not only everywhere, but is also attached to objects and users moving and interacting with the environment. For these mobile computing entities to communicate, wireless links should be evaluated, built and released in a dynamic, intelligent way. In this paper we analyze the specific case of mobile entities augmented with...
In this paper, we describe a radio-based localization approach that is based on the use of rotating directional antennas and a Bayesian network that combines both angle-of-arrival (AoA) and received signal strength (RSS). After describing our network, we extensively characterize the accuracy of our approach under a variety of measured signal distortion types. Next, using a combination of synthetic...
The current definition of the spatial channel model (SCM), presents all the components needed to represent the spatial behavior of the propagation channel for a given mobile. These components are used to generate the complex channel samples that evolve with time, but the position of the mobile remains constant, this is known as quasi motion simulation. As the SCM proposes an independent set of channel...
In this paper, we propose a route planning method for mobile sensor nodes using cost map. The proposed method achieves novel route planning that can solve several practical problems from previous works: the limitations of sensing ranges, obstacles on the node's routes, and restriction of their movements. This method can determine the route that has the lowest power consumption. We also propose a sensing...
