The mobility characteristic of Ad Hoc and Sensor networks implies that the topological information contained in the traditional IP address can no longer reflect the position of a node in the network. In this paper we propose a new approach to resolve the location-identification coupling contained in the IP address. The approach uses a Virtual Regular Structure (VRS) to describe the addressing space of the entire network; such a structure provides additional desired properties such as robustness and multi-paths. Our approach explores a distributed implementation of the VRS based on a trellis graph description of routing tables instead of the traditional trees. We show that the construction of the optimal structure is an NP-Complete problem; in this paper, we propose a heuristic and evaluate its performance via simulations
