A QoS Routing Protocol for Mobile Ad Hoc Networked Control Systems

摘要

Due to the dynamic topology, limited and shared bandwidth of the mobile ad hoc network (MANET), providing Quality of Service (QoS) for MANET-based Networked Control Systems (NCS) is a challenging task. This paper integrates the concept of choosing stable route according to Received Signal Strength Indication (RSSI) into AQOR. Considering the data packet transmission characters of NCS, we let the intermediate node repair routes for all the affected data flows and the destination node recover routes using a route update packet. The simulation results show that the improved protocol can reduce average end-to-end delay and loss rate, and enhance the stability of NCS.
