PROPOSED ENERGY AWARE ROUTING ALGORITHM FOR SOFTWARE DEFINED NETWORK

Software defined networking enhances network flexibility by split the control plane and the data plane, revolutionizing legacy network architecture by detaching control logic from forwarding devices. While SDN offers increased flexibility and programmability, routing algorithms play a vital role in determining how packets are forwarded. Proper assignment of controllers and switches is essential for creating energy-efficient networks. This paper reviews current routing techniques in SDN and proposes an algorithm aimed at reducing energy consumption in the network. The algorithm is designed to ensure efficient server allocation across various optimal scales, considering specific demands and link capacities, with the objective of minimizing overall power usage. We also compare the performance of this method with two other energy-aware routing (EAR) techniques, using shortest path routing algorithms for evaluation.Keywords: Energy aware routing, Optimization, Dynamic routing, IoT, Cloud computing
