A Wireless Sensor Network (WSN) is an infrastructure comprising of sensing, computing, and communication elements which gives as administrator the ability to instrument, observe, and react to events and phenomena in a hostile environment. This paper is to achieve prolonged network lifetime with overall energy efficiency in wireless sensor networks through controlled utilization of limited energy. Major percentage of energy in wireless sensor network is consumed during routing from source to destination, retransmission of data on packet loss. For improvement, cross layered algorithm is proposed for routing and retransmission scheme. Simulation and results shows that this approach can save the overall energy consumption.
