Abstract
Internet of Things (IoT) and Distributed Ledger Technologies (DLTs), are both young fields that are especially suited to covering low-power decentralized environments. We identify an under-studied niche of IoT Mobile Ad-hoc NETworks (MANETs) to best utilize DLTs, and challenge ourselves to put an entire cryptographically secure DLT on a $46 Arduino MKR WAN 1310. To accomplish this we create an open-source simulator for IoT-MANETs with several customizable modules: simple geo-spatial map, multiple DLT architectures, 3 wireless networks, consensus algorithms, mobile agent properties, storage optimizations, and Peer to Peer (P2P) gossip settings. We compare blockchains, Directed Acyclic Graphs (DAGs), HashGraphLight (a novel IoT-derivative of HashGraph) across Proof of Work (PoW) and Proof of Location (PoL). We then optimize the storage capacities, P2P set reconciliation, data throughput, and battery consumption to accommodate the Arduino. Most notably along the way, we illustrate that most DLTs throughput scale positively with denser networks, transaction redundancy is the biggest threat to storage overhead, design a two-stage set reconciliation answer for our uniquely bottlenecked environment, and prove that Long-Range Wide-area Network (LoRaWAN) is not viable for a gossip protocol. Ultimately, our simulator is the major product, an extremely customizable and fast abstraction of IoT-MANET DTLs that can guide the next person who asks: “What DLT is best?”
