INTRODUCTION A wireless sensor network is a collection of

wireless sensors covering a small area. Every sensor performs independent sensing

processing and transmission of data over wireless link with minimum power consumption.

These include low-energy signaling and networking

POWER AWARENESS FROM RADIO HARDWARE

The functionality of both transmitter and receiver are combined into a single device know as transceiver are used in sensor nodes.

The operational states are transmit ,receive , idle and sleep

Low Voltage Operation 1.8V minimum supply
