A multilayered algorithm for topology control and self-healing on Wireless Sensor Network
Santos Barrera, Hernán David · 2017
Wireless Sensor Networks play an important part on Internet of Things (IoT) but its implementation must take into account some constraints of the wireless devices that conform the network. Some of the biggest constrains are the limited power sources this kind of nodes rely on and unreliable wireless links, so it is imperative to implement different mechanisms for topology control and Self-healing to extend the network’s lifetime. We proposed and implemented using Contiki OS and Matlab a multilayered algorithm that: creates the topology for the network, divides in clusters the network, selects a Cluster Head (CH) and puts to sleep the Non-CHs nodes (preserving the battery of them) and finally implement a mechanism that creates disjoint paths and recovers when a parent of a node dies.
