Implementation of an On-Demand Routing Protocol for Wireless Sensor Networks

Overview

This paper presents their experiences in implementing and validating the on-demand EYES Source Routing protocol (ESR) in a real Wireless Sensor Network (WSN) environment. ESR has a fast recovery mechanism relying on MAC layer feedback to overcome frequent network topology changes resulting from node mobility and unreliability. A geographically restricted directional flooding scheme reduces energy consumption in the route re-establishment. ESR is implemented in their WSN environment consisting of EYES sensor node prototypes using the Lightweight Medium Access Control protocol (LMAC) on top of the AmbientRT operating system. They describe the key design and implementation features of the protocol and report experiment results of ESR and Ad hoc On-demand Distance Vector protocol (AODV), a conventional routing protocol for ad hoc networks.
