Overhead Evaluation of Bi-directional Data Exchange between OM2M and LWM2M using MQTT

Although machine-to-machine (M2M) frameworks, e.g., OneM2M and LWM2M, supports to interwork together, they may only provide uni-directional data convergence, i.e., from LWM2M to OneM2M. This paper studies and investigates the overhead of achieve bi-directional data exchange between two M2M frameworks using MQTT. In most conditions, the synchronization between two M2M frameworks may not add too much extra burden except the resource write procedure.
