Wireless sensor network’s localization based on multiple signal classification algorithm

Wireless sensor networks (WSNs) are a number of sensitive nodes senses physical phenomenon at the position their deployment then sends information to base station take appropriate operation. used in many applications such track military targets, discover fires, study natural phenomena as earthquakes, humidity, heat, etc. The spread large areas and it is difficult locate them manually because they published randomly by planes or any other method since received from useless without knowing location this case problem resulted positioning nodes. So unacceptable equip each node with global system (GPS) due various problems raises cost energy consumption. In paper explained non-GPS technique self-positioning using multiple signal classification (MUSIC) algorithm determine active through estimated direction arrival (DOA) signal. Then modified MUSIC (M-MUSIC) solve coherent MATLAB program successfully simulate proposed algorithm.
