Zusammenfassung

The ability to achieve security at physical layer has remained a formidable task for the research community. The difficulty increases in case of multiple cooperating (i.e. exchanging and combining information) eavesdroppers. Therefore, in this article, we characterize the secrecy rate that can be achieved in the presence of cooperating eavesdroppers between a sink and multiple sensor nodes i.e. SISOME scenario.

We quantify how the cooperating eavesdroppers using MRC (Maximal-Ratio Combining) and SD (Selection Diversity) techniques make it challenging to secure information. We then propose a scheduling scheme where a sensor with highest secrecy capacity is scheduled to transmit data. The analysis of intercept probability and secrecy outage probability clearly shows that using the scheduling scheme helps to provide greater security without any additional hardware complexity or power cost.
