A Multi-Path DSDV-Based Routing Protocol for WIA-PA Network

WIA-PA is a kind of wireless network for industrial process automation, which has a high requirement for the real-time and reliability of the data transmission. Based on the deficiency of the existing routing protocols, this paper puts forward a new kind of WIA-PA routing protocol MWD. The protocol chooses the stablest link in the routing table as the optimal route, and then based on the node disjoint strategy, determines a route as the backup route, which disjoints with the optimal routing node. When the node needs to transmit data, it can search the local routing table and choose the optimal route to transmit data. If the optimal route fails sometime, it can transmit data through backup route. The simulation results show that MWD protocol can enhance the real-time and reliability of the WIA-PA significantly.
