SMiRA: A bio-inspired fault tolerant routing algorithm for MANETs

Spiral Millipede-inspired Routing Algorithm (SMiRA) is presented as a bio-inspired approach for routing in MANETs. It has been designed as a resource light technique that reduces routing overhead and improves the level of tolerance to routing faults, amongst other things. It has been compared to the Ad-hoc On-demand Distance Vector (AODV). The results show an improvement in the monitored metrics, with a limited penalty. SMiRA has an average of 40.77% reduction is routing overhead and an average of 41.85% reduction in fault-tolerance latency, with an average of 3.118 s increase in node computational latency as the main penalty for an extremely resource limited Mica mote.
