Reliable Fault-Tolerant Multipath Routing Scheme for Wireless Sensor Networks
Several routing schemes have been designed in the recent years for wireless sensor networks (WSN). This protocol improves the reliability of data routing in WSN networks. In future WSN networks are expected to carry different traffic such as voice and video as well as data to serve both real and non-real time applications. Therefore, the reliability and quality of the data transmitted to support diverse applications is very important. In this paper, we proposed a new on demand routing protocol i.e. Reliable Fault-Tolerant Multipath (RFTM) routing protocol. RFTM is a multi-objective routing protocol that meets diverse application requirements. Proposed protocol improves both reliability and link quality to determine the number of desired multiple disjoint paths between the sink and source nodes. RFTM routing protocol provides the fault- tolerance and achieves the desired. Keywords— WSN, Multipath routing, RFTM routing scheme
