Wireless Sensor Networks is a combination of sensor nodes and base station also known as data collection unit. Sensor nodes in WSN's are thus responsible for performing the basic functions to provide better interaction between network and real time applications. Nodes collect data and forwarded it to sink node. Data transmission can be taken in either static or dynamic nature. In a static network scenario the problem of hotspot which is due to converge-cast can be improved using mobile sink. Using mobile sink delay can be reduced and data can be transmitted within time period in real time applications. In this paper we will discussed various techniques for sink placement and scheduling process with delay constraint. However the sleep-awake scheduling based on duty cycle is proposed in which sleeping time is divided into random sleep time and periodic sleep time.
