Multipath Routing Scheme for Industrial Real-time Wireless Sensor Networks

Abstract

Abstract-In the industrial scenes, the real-time property has to be considered in the data transmission. A novel routing scheme is proposed to reduce the packet loss rate effectively in the industrial wireless sensor networks. The scheme is based on Bellman-Ford algorithm, and saves some other shorter paths for the multipath transmission. According to different requirements of QoS in data transferring, the scheme can use more than one path to send the same packet synchronously. Moreover, the scheme use a unique label to mark every packet to assure that the receiver can discard the same packet from different path after a packet arrives in the receiver. Therefore, this scheme can reduce the probability of packet retransmission, and enhance the real-time property in the industrial wireless sensor networks.
