In this paper, we propose a fault-tolerant routing protocol, called Sensor On-demand Multi-path Distance Vector Reliable (SOMDV-R) routing protocol, for wireless sensor networks to support reliable data delivery. Instead of selecting a shortest path, SOMDV-R takes into account both reliability demand and link quality to determine the number of desired paths. Beside, to improve packet delivery rate upon band channel condition, SOMDV-R supports multipath data delivery. We evaluate our proposed protocol via simulations. The results show that compared with Ad hoc On-demand Multi-path Distance Vector (AOMDV) and AODV, SOMDV-R can achieve higher packet delivery rate, lower routing overhead and lower mean latency, upon different channel conditions.
