Wireless Sensor Networks holds space in wide range of application ranging from tracking to monitoring health, environment etc. The power (energy consumption) attribute for WSN requires special attention as WSN has to work unattended for long durations. Till now WSN nodes has been designed using low-power micro-controller. But still its power dissipation is high enough to limit its wide-spread use in new application. The authors propose an alternate model according to which customized hardware will be designed for each task of an application. The WSN node architecture will be divided into micro-tasks and these micro-tasks will be activated-deactivated by the system monitor which is an FSM (Finite State Machine).
