Ques : Describe challenges in Fog

Fog computing offers several advantages, but there are several challenges associated with it. Some of them are –

1. Complexity
   Fog devices can be diverse in architecture and located at different locations. Fog devices further store and analyse their own data hence add more complexity to the network.

2. Power Consumption : Fog devices require high power consumption for proper functioning. Adding more fog devices increases energy consumption, which results in an increase of cost.

3. Data Management
Data is distributed across multiple fog devices hence data management and maintaining consistency is challenging.

4. Authentication
Establishing trust and authentication may raise issues.

5. Security
Since there are many fog devices, each with a different IP. Getting access to personal data by spoofing, taping, and hacking can be a challenge.
