Energy consumption is the major problem in a wireless sensor network (WSN).In order to reduce the energy consumption, level by level offset based wake up pattern with hybrid data gathering protocol is introduced in this paper. This paper analyses the energy consumption in different nodes. The main purpose of WSN is to collect data for processing, communicating and reporting. For data reporting time driven and event driven schemes are used. There is a hybrid data gathering protocol that dynamically switches between the event driven and time driven data reporting schemes. By using this hybrid data gathering protocol with sleep scheduling, we can detect an event of interest in the near future with low energy consumption. Also we can predict the dissemination pattern of an event.
