Abstract

We investigate connection-level and packet-level quality-of-service (QoS) performances in a solar-powered wireless mesh network when a connection admission control (CAC) mechanism is used at each mesh node. A queueing analytical model is developed to evaluate the various performance measures at a mesh node considering a general sleep and wakeup mechanism and constrained power supply at that node. Based on this queueing model, we demonstrate how an optimization problem can be formulated to obtain the optimal sleep and wakeup parameters or the CAC threshold so that the desired QoS performance can be achieved under constrained power supply.
