Wireless Sensor Network (WSN) fulfills the requirements to solve real-life applications due to their unattended nature. But, the main constraint faced by researchers is the energy available with sensor nodes. The network should have a longer lifetime to offer better data aggregation. So there is a need to prolong the life of sensor nodes and thus WSN. It is necessary to design energy-efficient operational schemes. One of the most suitable approaches to enhance energy efficiency is the clustering scheme, which enhances the performance parameters of WSN. Thus Adaptive Ranking based Energy-efficient Opportunistic routing (AREOR) is an opportunistic scheme that creates dynamic clusters and offers a longer lifetime to the network due to its heuristic. This scheme is modified based on the cooperation of nodes termed Cooperation Federated-AREOR (CF-AREOR), further enhancing the network’s performance parameters. This protocol is implemented using a network simulator, and its performance is a
