The current trend in developing smart technology for the Internet of Things (IoT), has motivated interest in optimising data transmission or minimising energy consumption, with little evidence of proposals for achieving both of these
properties in a single model. Viewing the problem from a game theory perspective, we develop a new MAC protocol for IEEE 802.15.4 and IoT networks in which we formulate a novel expression for the players utility function and establish a stable Nash Equilibrium (NE) for the game.

The proposed IEEE 802.15.4 MAC protocol is modelled as a smart game in which expressions are derived for channel access probability, data transmission probability and energy. These expressions are used in formulating an Optimization Problem (OP) that maximizes data transmission and minimises
energy consumption by nodes. The analysis and simulation results suggest that the proposed scheme is scalable and achieves better performance in terms of data transmission, energy efficiency and longevity, when compared with the default IEEE 802.15.4 access mechanism.
