Abstract :
The IEEE 802.15.4 medium access control (MAC) protocol, which is widely used in current WSN deployments, does not provide any hidden node avoidance mechanisms. This leads to severe performance degradation in IEEE 802.15.4 MAC protocol in the presence of hidden nodes. In this paper, we apply a discrete-time Markov Chain model to analyse the throughput of IEEE 802.15.4 MAC protocol in the presence of hidden nodes. Based on the proposed model, the effects of network size, network topology, frame length and frame arrival rate on the throughput of the system are investigated.
