dynamic tree- based routing: applied in wireless sensor network and iot

The internet of things (iot) has advanced in parallel with the wireless sensor network (wsn) and the wsn is an iot empowerment. the iot, through the internet provides the connection between the defined objects in apprehending and supervising the environment. in some applications, the iot is converted into wsn with the same descriptions and limitations. working with wsn is limited to energy, memory and computational ability of the sensor nodes. this makes the energy consumption to be wise if protection of network reliability is sought. the newly developed and effective hierarchical and clustering techniques are to overcome these limitations. the method proposed in this article, regarding energy consumption reduction is tree-based hierarchical technique, used clustering based on dynamic structure. in this method, the location-based and time-based properties of the sensor nodes are applied leading to provision of a greedy method as to form the subtree leaves. the rest of the tree structure up to the root, would be formed by applying the centrality concept in the network theory by the base station. the simulation reveals that the scalability and fairness parameter in energy consumption compare to the similar method has improved, thus, prolonged network lifetime and reliability.
