Context-Aware Routing in Fog Computing Systems

Fog computing enables the execution of IoT applications on compute nodes which reside both in cloud and at edge network. To achieve this, most fog systems route data a path starts source, goes through various nodes. Each node this may accept if there are available resources to process locally. Otherwise, is forwarded next path. Notably, when (rather than accepted), communication latency increases by delay reach node. avoid we propose routing mechanism maintains history all that have accepted each context past. By processing history, our sends directly closest tends same context. This lowers forwarding path, can reduce latency. We evaluate approach using prototype- simulation-based experiments show reduced (by up 23 percent) lower number hops traveled 73 percent), compared state-of-the-art method.
