Introduction WISENET( Wireless Sensor Network )
One of MIT's 10 emerging technologies. A large number of low cost, low power,
multifunctional, and small sensor nodes. Sensor nodes consist of sensing, data
processing and communicating components. Collaborative effort of a large number of
nodes. Primarily focus on power consumption.

Sensor network Vs Ad-hoc network
Sensor nodes Number of sensor nodes is larger Densely deployed, prone to failures The topology of a sensor network changes
very frequently Mainly use broadcast Limited in power No global identification

• Smart power saving process.• Complete hardware design.• Digital Sensors.• Based on open source software.
ADVANTAGES
16
Copyright © Asish Aich, KIIT University, Bhubaneswar, India.
• Future Wireless Sensor Networks (WSNs) will be ubiquitous, large-scale networks interconnected with the existing IP infrastructure.
• Autonomic functionalities have to be designed in order to reduce the complexity of their operation and management, and support the dissemination of knowledge within a WSN.
