Demo: Brzzz - A Simplistic but Highly Useful Secondary Channel for WSNs
نویسندگان
چکیده
The wire is connected to an interrupt pin of an ATmega1284p MCU of an INGA sensor node. The input pins of this MCU are fused by two diodes per default. Thus, the potentially high voltage that is induced in the wire cannot harm the MCU. A pinchange interrupt is used to trigger the rising and the falling edge of the signal while a timer is fired to measure the period of positive half-waves of the signal. The resulting pattern can be further used to filter the pulses from other interference. Utilization

Multi-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

متن کاملCongestion Control Approaches Applied to Wireless Sensor Networks: A Survey
Wireless Sensor Networks (WSNs) are a specific category of wireless ad-hoc networks where their performance is highly affected by application, life time, storage capacity, processing power, topology changes, the communication medium and bandwidth. These limitations necessitate an effective data transport control in WSNs considering quality of service, energy efficiency, and congestion control. ...
متن کاملWSNLab – a Security Testbed and Security Architecture for WSNs
A Wireless Sensor Network (WSN) consists of small, resource-constrained computing devices (so-called motes) that perform physical measurements (e.g., temperature, vibration) in a distributed manner. The motes form a self-adaptive multihop network to transport the measured data to a sink. The data may be pre-processed and fused in the network. Furthermore, WSNs often provide capabilities using a...
متن کاملResistance to Flow in a V-Shaped Bottom Channel
Water flow in open channels is always subject to the resistance to flow and energy dissipation. For design purposes, one of the needed variables is the hydraulic resistance coefficient. For this mean, the influence of cross-sectional shape together with secondary flow cells and lateral distribution of true boundary shear stress have not yet been fully explored. This paper surveys the number of ...
