A novel scheme for congestion notification in IoT low power networks
Résumé
In this paper, we present a novel scheme for transmission of congestion state of IoT (Internet of things) low power nodes managed by a central entity. The proposed scheme enables an efficient aggregation of congestion state of nodes, in a given routing path, into a block called Congestion Information Block (CIB), which contains binary values representing the congestion state of nodes. Simulation results show that the proposed scheme provides a good performance compared to Explicit Congestion Notification mechanism (ECN) in terms of network throughput, network overhead and offers low divergence (regarding the time of observation) between the network congestion observed by the network manager and the real congestion of nodes.
