Low-power WSN Technology

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 1 –6

[Generally, a sensor node refers to any device that is capable to sense its environment. Wireless Sensor Network (WSN) as a technology is a collection of sensor devices that co-operate with each other. A WSN may comprise even thousands of autonomic and self-organizing nodes that combine...

Key Standards and Industry Specifications

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 7 –15

[A vast number of sensors exists in the sensor industry that can be used to measure physical parameters, such as temperature, pressure, humidity, illumination, gas, flow rate, strain, and acidity. Standardized sensor interfaces, data formats, and communication protocols are required to enable...

Hardware Platforms and Components

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 17 –26

[Sensor node platforms implement the physical layer (hardware) of the protocol stack. The hardware activity measured as the fraction of time the hardware is in an active state (processing data or receiving/transmitting a packet) may be below 1% in low data-rate monitoring applications. Thus, it...

Communication Protocols

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 27 –41

[Network protocols are typically divided into several distinct layers according to their responsibilities, which together form a protocol stack. Each layer has precisely defined interfaces, which permits flexible updates and changes in the software and hardware implementations in a modular...

Software and Middleware Services

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 43 –59

[The software components in WSNs include sensor operating systems and middleware as shown in Fig. 5.1. The purpose of these is to ease the application development by providing network access and allowing support for heterogeneous platforms with hardware abstraction.]
Available

Sensor Data Collection

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 61 –70

[While some sensor networks can operate independently, e.g. by performing smart actuation based on measured sensor readings, in a typical use case sensor data is collected and utilized outside the WSN [16]. This necessitates data collection facilities and a connection between the sensor network...

Experiments

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 71 –77

[This section presents TUTWSN as a case study of WSN performance. TUTWSN uses cross-layer design between network protocols and hardware platforms to achieve the requirements of target WSN applications.]

Summary

Suhonen, Jukka; Kohvakka, Mikko; Kaseva, Ville; Hämäläinen, Timo D.; Hännikäinen, Marko

Pages: 79 –80

[The requirements of a WSN are diversified. The magnitude of data collected from a sensor network vary from bytes per day (e.g. environmental sensing) to kilobits per second (e.g. camera image streaming in surveillance). Further, the number of nodes in a network varies from few nodes to thousands...
