A Novel Gateway Selection Protocol for Three-layers Integrated Wireless Networks

Energy conservation and high data rate requirements are considered as major challenges in wireless networks. In this work, we investigate the concept of three-layered networks, such that the proposed theory consists of smart grids, Mobile Ad-hoc Network (MANET), and satellite networks where all can be employed in different IoT platforms. We developed four performance metrics that applied in the MANET layer for multi-gateway selection. Also, we provided the MANET layer with a proper routing protocol which can reduce the amount of traffic pressure. The experimental results show the performance of our proposed approach in terms of quality, average delay, and the network load balance for different network’s conditions. Moreover, the numerical results prove that the proposed design for MANET can improve throughput performance, gateway lifetime, and packet transmission rate.
