Abstract: ZigBee is a protocol stack created specifically for control of sensor networks which is built on IEEE 802.15.4, this standard works for low data rate wireless personal area networks (WPAN). The IEEE 802.15.4 standard works on PHY and MAC Layer. The IEEE 802.15.4 has become the preferable PAN system for wireless sensor networks and many software and hardware platforms are based on it. The implementation and performance analysis of this standard is needed to understand the conceptual limitations of it. This standard is designed for low data rate, low power consumption, long battery life. The implementation & performance analysis of this standard is needed to understand the conceptual limitations of it. In this paper we have tried to improve Error rate performance and other affected factors of Zigbee Personal Area Network (PAN) using multiple transmitters on existing system with OQPSK modulation in AWGN channel environment..Here in ZigBee we are applying MISO architecture with ECC 160 Encryption/Decryption method. The idea to use both of the schemes to apply in the IEEE 802.15.4 standard comes from that ECC 160 has features of low power consumption, more enough security and very less complexity as compare to RSA 1024, AES and IBE. The Multi transmitter scheme consumes high power compare to existing system. Hence we got a solution for that to save some amount of energy in the ZigBee Upper Layer. From the simulation results we have found that our proposed multiple transmitters scheme (MISO) gives very better results on low SNR values comparatively with the existing Single Input Single Output (SISO) approach together with the ECC 160 Encryption / Decryption in ZigBee based wireless sensor network.
