The Energy Efficient Cooperative MIMO Technique for Hierarchical Clustering Protocol

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. Thus lots of researches have been done at various layer of communication to reduce the energy consumption of a sensor during the communicating the sense data. In this paper a scheme has been proposed to implement MIMO system in hierarchical clustering protocol and the results shows that above a certain distance a cooperative MIMO technique is more energy efficient than the conventional hierarchical clustering protocol.
