Opportunistic Spectrum Allocation for Interference Mitigation Amongst Coexisting Wireless Body Area Networks
Samaneh Movassaghi, David B. Smith, Mehran Abolhasan, Abbas Jamalipour
Article No.: 7
Wireless Body Area Networks (WBANs) are seen as the enabling technology for developing new generations of medical applications, such as remote health monitoring. As such it is expected that WBANs will predominantly transport mission-critical and...
We propose a new algorithm for the classical averaging problem for distributed wireless sensors networks. This subject has been studied extensively and there are many clever algorithms in the literature. These algorithms are based on the idea of...
Wireless energy transfer has recently emerged as a promising alternative to realize the vision of perpetual embedded sensing. However, this technology transforms the notion of energy from merely a node’s local commodity to, similarly to...
Wireless Sensor Networks (WSNs) are crucial in supporting continuous environmental monitoring, where sensor nodes are deployed and must remain operational to collect and transfer data from the environment to a base-station. However, sensor nodes...
Harmonium: Ultra Wideband Pulse Generation with Bandstitched Recovery for Fast, Accurate, and Robust Indoor Localization
Pat Pannuto, Benjamin Kempke, Li-Xuan Chuo, David Blaauw, Prabal Dutta
Article No.: 11
We introduce Harmonium, a novel ultra wideband (UWB) RF localization architecture that achieves decimeter-scale accuracy indoors. Harmonium strikes a balance between tag simplicity and processing complexity to provide fast and accurate...
Exploiting Electrical Grid for Accurate and Secure Clock Synchronization
Sreejaya Viswanathan, Rui Tan, David K. Y. Yau
Article No.: 12
Desynchronized clocks among network nodes in critical infrastructures can degrade system performance and even lead to safety incidents. Clock synchronization protocols based on network message exchanges, though widely used in current network...
Natural Timestamps in Powerline Electromagnetic Radiation
Yang Li, Rui Tan, David K. Y. Yau
Article No.: 13
The continuous fluctuation of electric network frequency (ENF) presents a fingerprint indicative of time, which we call natural timestamp. This article studies the time accuracy of these natural timestamps obtained from powerline...
Non-Bayesian Social Learning with Observation Reuse and Soft Switching
MD. Zulfiquar Ali Bhotto, Wee Peng Tay
Article No.: 14
We propose a non-Bayesian social learning update rule for agents in a network, which minimizes the sum of the Kullback-Leibler divergence between the true distribution generating the agents’ local observations and the agents’...
Differentiating Clear Channel Assessment Using Transmit Power Variation
Alex King, Utz Roedig
Article No.: 15
Clear Channel Assessment (CCA) is a core element of Wireless Sensor Network (WSN) Medium Access Control (MAC) protocols which is used on the transmitter and receiver sides. Current CCA implementations cannot determine the device type occupying the...
