Energy conservation at node level using a wake-up scheme in Wireless Sensor Networks

In Wireless Sensor Networks increasing the network life time without the possibility for replacing and recharging the batteries of a node for a long period is one of the challenging issues. Usually network level issues are considered to overcome this, but here we are considering node level energy conservation which will be more efficient when compared to that of network level. In this paper we are proposing a wake-up scheme for sensor node to reduce its energy consumption. This scheme will focus on the issues related to asynchronous wake-up of sensor node to reduce energy wastage, traffic load, congestion and collision in the network which in turn will increase the overall network lifetime.
