Multi-hop wireless sensor networks (WSN) have many applications in nowadays' environment monitoring. However, it is very challenging to predict the throughput for an arbitrary multi-hop wireless sensor network with different source data rates. In this paper, we propose an iterative decomposition method for this purpose. We first identify a limited number of basic network configuration of chain topology...
We consider the problem of clandestine communications, i.e., communications that are meant to be invisible to third-party eavesdroppers, in the context of wireless sensor networks. Although encryption and anonymous routing protocols can hide the content and the routing information, the transmission activities of sensors on the same route can still reveal the information flow. In this work, a perfectly...
We describe the design, development and learnings from the first phase of a rainforest ecological sensor network at Springbrook - part of a World Heritage precinct in South East Queensland. This first phase is part of a major initiative to develop the capability to provide reliable, long-term monitoring of rainforest ecosystems. We focus in particular on our analysis around energy and communication...
