Edge computing for internet of things

The success of Internet of Things (IoT) and rich cloud services has introduced new computing paradigm edge computing, which processes the data at the edge of the network . Edge computing has the potential to address the concerns of response time requirement, battery life constraint, bandwidth cost saving, as well as data safety and privacy. The paper evaluates the definition of Edge computing, Internet of Things. Due to enormous growth in Internet of Things (IoT) devices , there is need for real time computation which is fulfilled by Edge Computing. The paper covers the survey on edge computing and performance management towards IoT devices, characteristics and architecture of Edge computing over IoT devices. Finally it covers challenges and opportunities in the field of edge computing in IoT.
