Renewal Theory Based Performance Analysis for IEEE 802.15.4 MAC Protocol with ACK mode

In this study, we model and analyze an wireless sensor network. First, we develop an analytic model for the homogeneous network where all nodes in the network have the same traffic characteristic. For our model, we assume a sensor network with star topology which is operated using the IEEE 802.15.4 MAC protocol with ACK mode. From our analytical model we derive performance metrics such as throughput, mean service time of a packet, transmission success probability of an arbitrary packet, transmission failure (due to collision) probability of an arbitrary packet and CCA failure probability. Using our analytic model for the homogeneous sensor network, we also develop an analytic model for the non-homogeneous network where a tagged node called cluster header node in the network has different traffic characteristic than the other nodes called normal nodes.
