Abstract—Many applications in the smart grid generate packets with small data payload and may lead to low channel efficiency. In addition, some types of information exchanging from the smart meters to the control center is useful only within the predefined delay constraint. Hence, given that the concentrators are assigned a fixed amount of bandwidth, the maximal number of nodes that the smart grid wireless backhaul can support without violating their delay constraints becomes an important topic. In this study, we proposed to employ a deadline ordered scheduler with packet concatenation and obtained the call admission control (CAC) to resolve these two issues. The performance of this novel design were demonstrated via analytical and simulation results. It is shown that the proposed scheduler with packet concatenation significantly improves the capacity of the smart grid wireless backhaul.

Index Terms—Smart grid, wireless backhaul, deadline ordered scheduler, packet concatenation, call admission control, delay guarantees.
