Abstract
Next generation sensor networks are predicted to be deployed in the
Internet-of-the-Things (IoT) with a high level of heterogeneity. They will be using
sensor motes which are equipped with different sensing and communication
devices and tasked to deliver different services leading to different energy
consumption patterns. The application of traditional wireless sensor routing algorithms
designed for sensor motes expanding the same energy to such heterogeneous
networks may lead to energy unbalance and subsequent short-lived sensor
networks resulting from routing the sensor readings over the most overworked
sensor nodes while leaving the least used nodes idle. Building upon node interference
awareness and sensor devices service identification, we assess the relevance
of using a routing protocol that combines these two key features to achieve
efficient traffic engineering in IoT settings and its relative efficiency compared to
traditional sensor routing. Performance evaluation with simulation reveals clear
improvement of the proposed protocol vs. state of the art solutions in terms of
load balancing, notably for critical nodes that cover more services. Results show
that the proposed protocol considerably reduce the number of packets routed by
critical nodes, where the difference with the compared protocol becomes more
and more important as the number of nodes increases. Results also reveal clear
reduction in the average energy consumption.
