Recent development in microelectronics and signal processing enable more efficient use of wireless sensor network. Wireless sensor network finds its applicability in different area where the access of human being is so constrained. The sense data is being sent to the far situated user with the help of sensors. The different challenges of a wireless channel are bit error rate, signal attenuation and fading that occur in a wireless channel due to its unpredictable nature. Apart from this, using sensors for data transmission lots of energy is being consumed due to various mentioned constrained of wireless channel. A sensor mote is battery operated and fixed available power leads to network which posses a fixed life time.
