Abstract: The scope of the wireless communications in the recent years going to increase it is the way of constructing small sized, low power and inexpensive sensor devices that posses high-speed sensing, computational and communication capabilities. In this paper combination of hybrid hierarchical network topology and use of different communication techniques for Transmission (sleep & wait) and Reception/Listening (Low Power Listening). Energy efficient, energy conservation and hence improve sensor battery life is the main motive behind our work. In our proposed system, we setup intermediate nodes (parent nodes) in our system, so as to prevent direct communication between a sensor and Sink node, thus preventing large wait times for transmission.
