Systems, devices, and methods of execution one or more tasks in an Internet-of-Things (IoT) environment are disclosed herein. An exemplary method includes determining an event associated with overloading of a first sensor node in the IoT environment based on resources available in real-time on the first sensor node, wherein the event is determined based on number of tasks pending for execution at the first sensor node. Further, the method includes identifying the one or more tasks executable by a second sensor node. Furthermore, the method includes establishing communication with the second sensor node in the IoT environment and assigning the one or more tasks to the second sensor node such that the second sensor node executes the one or more tasks.
