Optimum modulation technique for modulating RSSI in WSN

Wireless Sensor networks due to their numerous applications have newly concerned a lot of interest in the research side. WSN is an organized network which became a brand new acquisition and processing information technology. RSSI (Received Signal Strength Indicator) values are used in WSN to find the distance based on the received signal strength. To avoid signal interference those values has to be modulated. Energy is the scare resource in WSN. In order to use energy in the best way, choosing best modulation technique for modulating RSSI is necessary. Best modulation technique will enable long distance transmission of data with minimum error. The location model of RSSI finds an optimum modulation technique in terms of energy consumption. Here the system deals with optimum M-ary modulation technique that has high energy efficiency in terms of modulation level and modulation ratio.
