Operator Migration for Distributed Complex Event Processing in Device-to-Device Based Networks
Rahul Chini Dwarakanath, Boris Koldehofe, Ralf Steinmetz · 2016
Recent times have seen a surge in the number of context-aware systems, given the proliferation of sensors and sensor-based devices, especially with the advent of new paradigms such as the Internet of Things (IoT) and device-to-device (D2D) communication. Complex event processing (CEP) provides a cogent means to obtain higher-level context information from low-level sensor data streams through operator graphs, which dictate the order of event processing steps. However, the reliable execution of these operator graphs in a distributed manner becomes increasingly challenging in dynamic D2D environments, especially when device availability fluctuates, necessitating efficient operator migration strategies. In this paper, we first analyze the existing efforts towards operator migration for their applicability in D2D-based networks. Subsequently, we propose our initial approach for reliable operator migration by exploiting the intermediate states of the CEP operators.
