Security in Opportunistic Networks

Security is of paramount importance in Opportunistic Networks (OppNets) due to its unique characteristics and operational challenges. OppNets are designed for environments with intermittent or disrupted connectivity such as disaster recovery. In such scenarios, traditional end-to-end communication models may not be feasible, making OppNets a crucial communication solution. However, the lack of continuous connectivity exposes data to potential vulnerabilities, including interception, tampering, and unauthorized access. The vulnerabilities that OppNets face are not the same as the ones faced by traditional networks. In this chapter, we discuss the main security concerns of OppNets.
