On the tuning of wireless heterogeneous routing

Multi-radio multi-channel (MR-MC) ad hoc networks pose new configuration challenges, including routing. Although a large number of works exist that investigate the tuning of routing parameter settings, to the best of our knowledge, none of them investigates the impact of heterogeneity and the tuning of parameters on convergence interval and energy consumption. Heterogeneous Technologies Routing (HTR) is a soft-state framework suitable for interconnecting devices in a heterogeneous ad hoc network. In this paper, we investigate the impacts of tuning the HELLO refresh interval timer on the convergence of the HTR protocol and its subsequent energy consumption during this phase. We also compare our tuned HTR with the widely used Optimized Link State Routing (OLSR) protocol. The evaluation is validated through simulation using heterogeneous technologies such as WiMAX, 3GPP LTE and Wi-Fi. Results show that varying the HELLO refresh interval can improve the convergence time and reduce the energy consumption without major impact on network behavior.
