Directional Multi-path Routing Algorithm Based on BLE Mesh

In this work, Bluetooth Low Energy (BLE) Mesh technology is applied to home health monitoring system, the existing Cambridge Silicon Radio (CSR) Mesh algorithm and Ad-hoc On-demand Distance Vector Routing (AODV) algorithm cannot guarantee the stability of data transmission because the guardian is often in mobile state. To solve the above problems, a directional multipath routing algorithm is proposed. It introduced the directional link quality indicator to help establish routing strategies. The simulation results show that the algorithm has higher delivery rate and better stability.
