1 IP Based Telecommunication – MTEL Mercubuana University Created By : Peby Wahyu Purnawan Emilia Roza Ratri Priyandewi

2  A WSN is a network consisting of numerous sensor nodes with sensing, wireless communications and computing capabilities.  Wireless sensor nodes constituting a WSN consist of a sensor interface, microcontroller, memory and battery units together with a radio module. Hence, wireless sensor nodes are able to carry out distributed sensing and data processing, and to share the collected data using radio communications.  Networks of typically small, battery-powered, wireless devices. ◦ On-board processing, ◦ Communication, and ◦ Sensing capabilities. Sensors Processor Radio Storage POWERPOWER

3  Wireless Sensor Networks (WSN) consist of tiny computers embedded into the environment that can monitor almost anything - such as light, motion, proximity, temperature, biometrics and chemical substances.[1]

9 WSN was born because of technological development, which starts from the emergence of the DSN (Distribution Sensor Network) and then on to associate with less wireless technology. Which until now has much in use in many areas.

10 Why are WSNs challenging/unique from a research point of view?  Typically, severely energy constrained. ◦ Limited energy sources (e.g., batteries). ◦ Trade-off between performance and lifetime.  Self-organizing and self-healing. ◦ Remote deployments.  Scalable. ◦ Arbitrarily large number of nodes.

11  Heterogeneity. ◦ Devices with varied capabilities. ◦ Different sensor modalities. ◦ Hierarchical deployments.  Adaptability. ◦ Adjust to operating conditions and changes in application requirements.  Security and privacy. ◦ Potentially sensitive information. ◦ Hostile environments.

12 WSN was first introduced in 2001, by Defense Advanced Research Projects Agency (DARPA) as a vanguard at United State of America. Defense Advanced Research Projects Agency (DARPA) spearheaded the wave of sensor network research by introducing new IT Sensor.

13 The workings of WSN is not as complex as the other operating system because of the specificity of gear on WSN. WSN has a sensor for detecting sensitivity requires both a form of touch / pressure, temperature, humidity and so on. sensor in analog form is converted into digital signals. Stored in memory. Microcontroller is more often used for WSN, as more flexible for use on any device and less costly.

14  Monitoring. ◦ Scientific, ecological applications.  Non-intrusiveness.  Real-time, high spatial-temporal resolution.  Remote, hard-to-access areas.  Surveillance and tracking. ◦ Reconnaissance. ◦ Perimeter control.  “Smart” Environments. ◦ Agriculture. ◦ Manufacturing/industrial processes.
