Evaluation of energy consumption in multipath OLSR routing in Smart City applications

The current advances of smart devices embedded with sensors have led to catalyzing the mobile ad hoc networks (MANET) in the Smart Cities. However, the energy consumption during routing are still challenging in such ensemble mobile environments. In this study, we compare and analyze the energy consumption of the Multi-Path-Optimized Link State Routing (MP-OLSR) and the Dynamic MANET On-demand (DYMO). The simulation involves Internet-based traffic for the Internet of Things (IoT) and Smart City applications using different simulation models. Particular performance metrics were selected to assess the effect of the network size and load traffic on the considered protocols. It was found that the MP-OLSR protocol consumed lower energy compared to DYMO when transmitting and receiving packets by taking advantage of its multiple paths policy. However, during idle mode, the DYMO protocol can perform better, especially in the low traffic scenarios.
