Energy Efficient Multi Path Routing Protocol in Internet of Things

Internet of things (IoT) is a network with a wide range of smart and physical objects and gadgets that can exchange information with each other. IOT introduces a variety of services that human life is dependent on its secure and accessible activities. These networks face numerous problems in terms of energy consumption and reliable communication to send the correct data. Moreover, the characteristics of these networks, such as the dynamism of their topology and the presence of energy constraints due to their wireless property led to challenges in the routing problem. The AOMDV protocol is one of the multi-path protocols that has been designed to maintain the balance of traffic load, management and control of energy consumption of nodes, delay deduction and etc. It uses several different paths to send it has a weakness in terms of the rate of package loss. In this article, an improvement of AOMDV called EEA_IOT is presented where the routes with high energy are selected for sending packets. To this end, the format of the AOMDV packets and some fields are added to so that the energy criterion is considered for routing in IOT. To demonstrate the efficiency of the proposed method, it is compared to AOMDV and SMG through two different scenarios in terms of packet loss rate and residual energy. The results indicate a better performance of the proposed method.
