A Dynamic Relay Handover Technology for the Paired Slot Relay of JTIDS under Selective Attacks

In this paper we present a novel technology named Probability Dynamic Relay Handover (PDRH) for the benefit of providing a mechanism to recover from selective attacks on some important terminals of JTIDS. The key points of PDRH are the probability model to simulate selective attacks using the theory of scale-free network and addressing for a new relay node. In simulation based on OPNET Modeler 10.5, the effect of PDRH on the network performance and survivability are estimated according to the mostly used network performance indices and some new indices proposed. The results indicate that as a candidate relay handover technology for the paired slot relay, PDRH can largely improve the survivability of JTIDS under the attacks on the important terminals, while the extra cost on the network resources is little.
