© 2014 IEEE. This paper presents an adaptive radio resource management (RRM) scheme to meet the diverse QoS requirements of bursty machine-to-machine (M2M) applications in the Smart Grid. The key features of the proposed RRM scheme include a differentiated random access scheme based on the virtual ranging channel (VRC) concept; a dynamic rangingcode allocation scheme to ensure an efficient utilization of the random access resources; and a prioritized grant allocation scheme to meet the delay bounds of the time critical data-packets. The performance of the proposed RRM scheme is demonstrated using an OPNET simulation model, and benchmarked against the conventional scheme.
