Hierarchical Numbering Based Addressing and Stateless Routing Scheme for Wireless Sensor Networks
Source: Taylor & Francis Group
Due to energy and other relevant constraints, addressing of nodes and data routing techniques in sensor networks differ significantly from other networks. In this paper, the authors present an energy-efficient addressing and stateless routing paradigm for wireless sensor networks. They propose a dynamic and globally unique address allocation scheme for sensors in such a way that these addresses can later be used for data routing. They build a tree like organization of sensors rooted by the sink node based on their transmission adjacency and then set labels on each sensor with a number according to the preorder traversal of the tree from the root.
