  1. Fault Tolerant Algorithm for Multi Hop Wireless Sensor Networks • Features • Rerouting capability on failure • Fault Tolerance through hardware redundancy • Isolation and self-recovery • Supports mobile sensor networks • Deployment of data mule to fetch/bridge isolated nodes. • Built using Contiki OS and LNPD • Used Reliable Unicast protocol in Rime communication stack of Contiki to mote-mote communicate • Used periodic broadcast for dynamic ad-hoc network formation. • LNPD is used for directing RCX data mule to bridge nodes • Used serial communication from mote to PC for instructing RCX
