A Hierarchical Routing Protocol for Sensor Network Reconfiguration

IP address assignment for sensor nodes is a principle technique for realizing IP-USN in which IP-based network takes the place of Zigbee-based one. However, as conventional hierarchical routing methods do not consider end-nodes, those only can support a simple path search. Therefore, those are not adequate in dynamic sensor network environments. In this paper, we propose ComHRP (complement HRP) that inherits advantages of conventional methods. We also present address assignment and search techniques according to ComHRP. Network organizations can be simplified with ComHRP thereby mitigating the complexity of networks. Moreover, network reconfiguration, which is unpredictable by the nature of ubiquitous sensor networks, can be efficiently processed with our method.
