Abstract: The application areas of wireless sensor networks (WSN) have attracted more number of researchers to add more functionality to these networks with the inclusion of internet access to the devices in a network. These devices create a network by utilization of internet to form Internet of Things (IoT).As the sensors and actuators are collecting various types of data in WSN, the need for storing and manipulating the heterogeneous sensor data is essential.The objective of the current work is to analyze the heterogeneous IoT data obtained from WSN by optimizing the routing path using greedy perimeter stateless routing (GPSR) protocol.Public sensing framework is deployed on large-scale network with low-cost by the utilization of currently available sensors where data already being shared among users.
