In this paper, the authors present a discrete stochastic model for information traffic flow through wireless networks. Many wireless nodes are powered by batteries. Thus, the number and buffer size of wireless nodes would greatly affect the performance of the system. The performance analysis is based on the throughput (J) - density relationship. It is shown that the system may exist in one of three steady-state regions: Low Density (LD), High-Density (HD) and Maximal-Current (MC). In the MC region, the maximal throughput 0.5 is reached. The LD region corresponds to free flow; while the HD region is congested traffic with J=1.
