A Priority-Aware MAC Protocol for the Smart City

Abstract

We propose a contention-based priority wireless reservation MAC protocol that guarantees latency and throughput for users with time-critical applications. The protocol is designed to accommodate two anticipated requirements of Smart City networks: first, that critical traffic be served within a specified delay without excessive throttling of non-critical traffic; and second, that surges in critical traffic from a geographically-concentrated region be handled gracefully without expansive overprovisioning.
