Optimizing the use of the limited energy resource in a mobile wireless sensor network (MWSN) is a key challenge for researchers to maintain longer network survival. This paper attempts to provide an energy-efficient data routing solution for large MWSNs. The aim of this work is to propose a cluster-based scheduling protocol for MWSN. The network is firstly divided into an optimal number of clusters according to sensors connectivity. Secondly, a sleep scheduling algorithm is proposed to save the energy consumption by turning off the overlapped nodes in the sensing field. This method is distributed among sensors in each cluster. It is based on the perimeter coverage level of mobile nodes to schedule their activities according to their weights. The weight is used to promote the energy efficiency criterian for all sensors in a cluster. The proposed approach ranges from sensors deployment, their organization to their operational mode. Experimental results demonstrate that the proposed cluster-based scheduling algorithm, based on the perimeter coverage of sensors, provides higher energy efficiency and longer lifetime coverage for MWSNs as compared to other protocols.

In this paper, the design and implementation of an asynchronously-triggered spiking neuron tailored for FPGA implementations is presented. The asynchronous triggering mechanism is designed to effectively preserve the spatial-temporal information captured by event-based vision sensors. Neurons of the target network model are implemented using the configurable logic blocks of an FPGA spatially and communicate through an asynchronous handshaking protocol. Without using a global clock to synchronize operations of the neurons, energy consumption and inference latency are minimized. The proposed design is composable and scalable for applications with different spiking neural network (SNN) configurations. Experimental results show that the proposed design is able to achieve 95.76% accuracy on the N-MNIST dataset while consuming less than 1 mW dynamic power on an Xilinx ZCU102 board.

Technological progress has opened the door for the development of measurements performed by interconnected distributed components. Legal requirements to put such measuring instruments on the market, such as the Measuring Instruments Directive (MID) in Europe, do not yet address this new kind of instruments and therefore might require revisions. To identify necessary modifications, a general list of components is derived, forming the proposed baseline of any type of distributed measuring systems. Based on the MID, assets to be protected and associated security properties are formulated for each of the described general components. By utilizing the recently revised general requirements for software-controlled measuring instruments of the international Organization of Legal Metrology (OIML), the necessary interpretations and changes to fully protect all assets of a generalized distributed measuring system are shown and analysed. Finally, a summary of this investigation presents the current and potential future state of sensor networks under a legal metrology framework.
