Fog Computing in IoT
Even though the demand of cloud computing is on rise, it involves an inherent problems related to very less mobility as well as location-awareness, along with unreliable latency. These drawbacks make cloud computing very unfeasible solution for applications like IoT. It is fog computing which addresses these difficulties as it provides very elastic resource as well as services till the end devices at the very edge of network, and cloud computing will take more care of fulfilling demand of resources distributed at the core of the network. Computer scientists and researchers had recently gained interest in this paradigm of remote computing as it provide computational efficiency of a cloud and bandwidth efficiency of a local network. This paper reviews the state of the art of FOG computing, its challenges, application and its comparison with cloud.
