What is multimedia WSN?
As a result, Wireless Multimedia Sensor Network (WMSN) [6] is a network of wirelessly interconnected sensor nodes equipped with multimedia devices, such as cameras and microphones, and capable to retrieve video and audio streams, still images, as well as scalar sensor data.
What is WSN explain the application examples of WSN?
Area monitoring is a common application of WSNs. In area monitoring, the WSN is deployed over a region where some phenomenon is to be monitored. A military example is the use of sensors to detect enemy intrusion; a civilian example is the geo-fencing of gas or oil pipelines.
Which technology is used in WSN?
Two primary technologies of WSN, location awareness and data fusion, are elaborated. Basic contents, main methods and their merits as well as shortcomings, and expectations of future development trends are reviewed. WSN still owns a promising future with broad developing prospects, more intelligent and more integrated.

Which is a one of the most popular wireless technology is used by WSN?
Wireless M-Bus and KNX RF Multi are standards optimized for battery operation. The most common operating frequency is 868 MHz, giving better range than solutions based on 2.45 GHz.
How are sensor networks beneficial in healthcare?
Embedded in a variety of medical instruments for use at hospitals, clinics, and homes, sensors provide patients and their healthcare providers insight into physiological and physical health states that are critical to the detection, diagnosis, treatment, and management of ailments.
What are the challenges of multimedia WSN?
Multi-media sensor nodes are typically deployed in a pre- planned manner into the environment to guarantee coverage. Challenges in such WSN include high bandwidth demand, high energy consumption, quality of service (QoS) provisioning, data processing and compressing techniques, and cross-layer design.
What is Battlefield Surveillance in military?
During conflict, the battlefield surveillance mission is to detect, locate, identify, and monitor changes in the enemy’s resources: tanks and other vehicles, helicopters, motorized troops, air defense batteries, etc. It must enable target acquisition for the artillery or for tactical aviation forces.
How structural health monitoring is performed by a WSN?
By using Microelectromechanical Systems (MEMS) Accelerometer we can perform Structural Health Monitoring by studying the dynamic response through measure of ambient vibrations and strong motion of such structures.
