Abstract: This study evaluated the performance of IEEE 802.15.4 network in the case of applying Alamouti scheme using both 2 × 1 multiple-input single-output (MISO) and 2 × 2 multiple-input multiple-output (MIMO) antenna configurations. The modulation curves, i.e., bit error rate (BER) vs. signal-to-noise ratio (SNR) of the conventional IEEE 802.15.4, switching diversity, Alamouti scheme are obtained first. Using the modulation curves, performance of IEEE 802.15.4 network is investigated. Throughput, probability of successful transmission and energy efficiency are used as measures of performance. Simulations are performed to prove the effectiveness of applied Alamouti scheme in the viewpoint of IEEE 802.15.4 network.
