A Backup Relay Technology for the Paired Slot Relay of JTIDS

In this paper we present a novel technology named Dynamic Relay Handover (DRH) for leveraging DSR and AODV for the benefit of providing a guaranteed network performance. The key points of DRH are the connectivity checking of the existing relay node and the assignment of a new relay node. In simulation of this algorithm based on OPNET Modeler 10.5, the effect of DRH on the network performance and the invulnerability is estimated according to the mostly used network performance indices and some new indices we propose. The simulation results indicate that as a backup relay mode for the paired slot relay, DRH can largely improve the invulnerability of JTIDS, while the extra cost on the network resources is little.
