Treffer: ATP: Adaptive Tuning Protocol for Service Discovery in Internet of Things

Energy is a precious resource in Internet of Things (IoT) especially with battery operated nodes, the overhead that consumes the battery power of the sensor nodes is a fundamental problem. This overhead is mainly caused by the frequent update messages sent to service directories. Although this problem has been investigated in the literature, it is still in its infancy as existing works do not consider the dynamic adjustments of the update messages. To fill in this gap, this paper presents a new adaptive tuning approach between sensor nodes and the resource directory to adjust the frequency of updates based on the battery level of the sensing node. Our protocol works dynamically in both modes, stateless and stateful service registration mechanisms.
