WIRELESS SENSOR NETWORK

On 19 September 2014, CSE & IT Department of Dronacharya college of Engineering, Gurgaon Organized a Guest Lecture on “Wireless Sensor network”. The main Speaker was D.K. Lobiyal who is Professor at School of Computer & Systems Sciences, JNU, New Delhi. A wireless sensor network (WSN) is a set of sensor nodes and each sensor of the network can measure certain physical phenomena like temperature, pressure, intensity of light or vibrations around it. Wireless networks of such sensor nodes have many potential applications, such as Surveillance, environment monitoring and biological detection. Prof D.K. Lobiyal focused on Characteristics and applications of Wireless Sensor Network. He also emphasizes on research area in wireless sensor network.

Wireless Sensor Networks (WSN) has recently been the focus of a significant amount of attention and effort of the research community. The main focus has been to address the challenges posed by the WSN paradigm, i.e., limited node power, processing, and communication capabilities, dense network deployment, multi-hop communications, and heterogeneous application-specific requirements. WMSN applications, e.g., multimedia surveillance networks, target tracking, environmental monitoring, and traffic management systems, require effective harvesting and communication of event features in the form of multimedia such as audio, image, and video. To this end, additional challenges for energy-efficient multimedia processing and communication in WMSN, i.e., heterogeneous multimedia reliability definitions, tight QoS expectations, and high bandwidth demands, must be addressed as well.
