| Renewable energy and green technologies are important global topics that are expected to affect the way of life of future generations. Deploying a green wireless principle will help to reduce the world's dependency on fossil fuels, consequently lowering carbon dioxide and other emissions as will. In this thesis, we propose a new approach to employ the Stream Control Transmission Protocol (SCTP) in a heterogeneous network of wired and wireless/mobile nodes while maintaining quality and reliability of service availability when switching power sources. This switching between sources exists in situations where a renewable energy (e.g., solar or wind) fed small cell base station (green cellular) is used as an alternative and assistant to a traditional energy fed base station. Since renewable energy sources may not be reliable at all times, the proposed system employs SCTP to make the handover between a base station fed by renewable energy source and another base station fed by conventional energy source. If the renewable energy source becomes unreliable for even a few seconds, the system is switched over to the traditional base station fed by conventional energy source, until the renewable energy fed base station is once again reliable. Simulation results are presented to show that SCTP can manage the handover between the conventional energy fed base stations and renewable energy fed base stations smoothly, even when renewable energy sources are not stable and the energy level fluctuates. |
