ZigBee is a protocol created specifically for control of sensor networks. It Built on IEEE 802.15.4, the standard for low data rate wireless personal area networks (WPANs). 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. In this paper we have tried to improve Error rate performance of Zigbee Personal Area Network (PAN) using multiple transmitters on existing system with OQPSK modulation in AWGN channel environment. From the simulation results we have found that our proposed multiple transmitters scheme (MISO) gives quite batter results on low SNR values comparatively with the existing Single Input Single Output (SISO) approach.
