Traffic and Energy Aware Routing for Heterogeneous Wireless Sensor Networks
Traffic and Energy Aware Routing for Heterogeneous Wireless Sensor Networks.Routing algorithm’s energy-efficiency is crucial to enhancing the lifetime of battery-restricted wireless sensor networks (WSNs). It is essential to consider nodes heterogeneity in routing in order to achieve optimal use of resources.
This letter considers sensor nodes with random initial energies and random data generation (traffic) disparities to model a realistic clustering-based WSN that is suitable for heterogeneous sensing applications.
The letter presents an energy model for the scenario and proposes a traffic and energy aware routing (TEAR) scheme to improve the stability period. The simulation results indicate that TEAR outperforms other clustering-based routing algorithms under the scenario.
