Search and routing in large area hierarchical IoT networks

Abstract

The world wide use of the public internet has opened up the possibility of applying similar technology for automated functioning of physical objects equipped with micro electronic devices. The perception is to apply that kind of technology to various areas of human activity for enhancing the quality and scale of performance. Starting from automated homes, the possibility of application are projected to be in efficient transport systems, energy management, smart cities, industrial automation, environmental monitoring, business management, defense operations etc. Such activities require huge network support, deployed over vast areas of the globe with suitable taxonomy for fast connectivity and operation. In this paper, it is suggested that the network is hierarchical having hybrid tree graph architecture, with the root node as the overall controlling headquarter. The hierarchy of the nodal stations is assumed to be based on the geographical distance from the root node, in which the nodes having the same hierarchy are also linked by collateral bus connectivity. The search of a node and routing data to the destination is carried out along a path which is as close as possible along the geographical direction of the location of that destination. Such a procedure was earlier developed by this author [19], [20], accounting fully for the sphericity of the globe. Accordingly, an algorithm for the search and routing in the envisaged network is presented in conclusion.
