This paper presents a lightweight data compression method for wireless sensor networks monitoring environmental parameters with low resolution sensors. Instead of attempting to devise novel ad hoc algorithms, we show that, given general knowledge of the parameters that must be monitored, it is possible to efficiently employ conventional Huffman coding to(More)
This paper studies the performance of asynchronous consensus algorithms in wireless sensors networks (WSNs). The application of such distributed consensus algorithms for the estimation of parameters or detection of events in WSNs has attracted increased attention recently. In this work the reliability of the wireless links between nodes is modeled by the(More)
