Abstract: Sensing technology is a cornerstone for many industrial applications. Manufacturing plants and engineering facilities, such as shipboard engine rooms, require sensors to ensure product quality and efficient and safe operation. Due to its scalability and efficiency, multipath routing has gained much research attention in routing primitive in wireless sensor networks (WSN). However, in multipath routing, due to ad hoc or random deployments and network dynamics of WSN, communication holes may exist in a network area. For long life efficient network need some recovery strategies for avoiding holes and smooth transmission of data. This paper explores the recovery strategy for an urgent transmission, forwarded packets through alternative path does exist in the multipath routing. For enduring shortest transmission, this paper proposed to reuse the same primary path, by replacing the holes using the redundant sensors.
