Several wireless sensor network applications have to to decide the inherent discrepancy between energy efficient communication, power aware routing and the requirement to attain preferred quality of service (QoS) such as packet delivery ratio, delay and to reduce the power and energy consumption of wireless sensor nodes. In addition to that the protocols which are developed aims in providing better QoS. For addressing this challenge, we propose the Power Aware and Energy Efficient Routing

... ol (PAEERP), which attains application-specified communication delays at low energy cost by dynamically adapting transmission power and routing decisions along with incorporating a novel cryptosystem. Through extensive simulation in NS2 the results prove that the proposed PAEERP attains lesser delay with reduced power and energy consumption.
