Abstract
The IoT devices in remote areas are very much vulnerable. The data collecting hub is not secured for recent attacks. The data transferred is attacked before reaching the server. In the existing system, the blockchain is used for data aggregation. The data is secured by this technique but the cost of performing this is very high. In the proposed system the data aggregation is done by using multiple block chains which increase performance as well as the security provided. After receiving the data, the land sliding is predicted with heuristics. The device energy will be consumed very low when compared to the existing system. Security will be high by using multiple chains. The overload of mining and cryptography will be avoided.
