There are enormous numbers of applications of Wireless Sensor Networks (WSNs) ranging from small scale to large scale for military, agriculture, education, health, structural monitor, surveillance etc. Size of sensor nodes enables many more applications. Advancement in nanotechnology, mechanical engineering, electrical engineering, communication engineering and computing engineering help in designing a new device which is known as sensor nodes. These devices do computation, communication and sensing. This paper presents a new application namely efficient management of technical session like conference/workshop etc. of wireless network/Wireless Sensor Networks (WSNs).
