Abstract
Distributed Hash Table (DHT)-based protocols having the structure of a ring, are promotive solutions to randomly deployed location unaware Wireless Sensor Networks (WSN). These protocols are able to ensure routing and data management efficiently and independently from any location information. However, their bootstrapping phase is challenging since each node should be well positioned into a global virtual ring at the same time. Simultaneous nodes joining leads to multiple inconsistencies. Moreover, existing DHT-based bootstrapping protocols do not take into account nodes heterogeneity whereas most of WSN are nowadays heterogeneous. In this paper, we propose an energy-aware bootstrapping protocol that not only organizes directly the nodes into a global consistent virtual ring but also allows it to build an energy efficient backbone for routing and data management. Simulation results show that our bootstrapping protocol improves drastically the DHT-based routing protocol performance and extends the network lifetime.
