A survey on design and analysis of robust IoT architecture

The IoT technology creates revolutionary changes in data exchange and device control in different applications. As the IoT network grows it tosses different challenges to engineers and researchers. As the network grows the size of the communicating and processed data also increases. In many cases the clients demands the history of data. To retain the past data large storage disks are in demand. Getting past data may help in data investigation to understand the system behaviour and to estimate its intelligence. Sometimes it is also very important in law-breaking investigation or in case of offence. Then going on adding the storage disks will not satisfy the user demands, buts it pops many other critical issues for both analysists and clients. The increase in disk size and quantity will increase the cost. It may also decrease the performance of the system. For small and individual personal systems this may become an obstacle. For an individual the patriotic IoT may become an expensive and lazy tool to maintain. This creates lots of problem in their daily life. This creates unwanted and unnecessary troubles in the routine life. The large data can be stored in cloud and can be retrieved from cloud data bases. But dynamic reading and storage is a biggest challenge for embedded systems used in IoT. Because of the network speed, data losses in wireless transport and port synchronization problem the data chunks may not arrive at port stand. This need to be intimated to user with acknowledgement signals. For storing real time data entity high speed data RAMs and internal storage devices are embedded in IoT modules. All operations in IoT system are monitored by a microcontroller contained motherboard. In simple and small IoT systems like personal or an individual systems single microcontroller instead of general purpose is sufficient. To reduce the burden on the microcontroller a co-processor can be used. In the present paper a method is proposed to access the data parameters without intervention of main processor. In this method a Direct Memory controller (DMA) is used to fetch the real parameters.
