The deployment of Wireless Sensor Networks (WSNs) in the mostly linear large structures, such as rivers, pipelines, etc, suffers from being the worst case for classical addressing schemes, e.g. Distributed Address Assignment Mechanism (DAAM) or stochastic addressing for Zigbee. Using DAAM for physical topologies composed of long lines of nodes connected together wastes addresses and generates orphan nodes. We show in this paper the inherent limitations of classical (DAAM, stochastic) and specialized (usually cluster-orientated) addressing schemes for Linear WSNs. DiscoProto, is an addressing and routing scheme which builds a logical network corresponding to a corresponding physical linear network without any knowledge of physical topology. In this paper, we show thanks to a realistic simulation using Castalia (Omnet based simulator) that DiscoProto avoids waste of addresses and allows a high association ratio. We also propose a dynamic version of our protocol called Dynamic DiscoProto in the second part of the paper. Dynamic DiscoProto allows to add new nodes or new branches in an existing linear network.
