Abstract
The performance of data delivery in wireless relay networks (WRNs), such as
delay-tolerant networks and device-to-device communications heavily relies on
the cooperation of mobile nodes (i.e., users and their carried devices).
However, selfish nodes may refuse to relay data to others or share their
resources with them due to various reasons, such as resource limitations or
social preferences. Meanwhile, misbehaving nodes can launch different types of
internal attacks (e.g., blackhole and trust-related attacks) to disrupt the
normal operation of the network. Numerous mechanisms have been recently
proposed to establish secure and efficient communications in WRNs in the
presence of selfish and malicious nodes (referred as non-cooperative WRNs). In
this paper, we present an in-depth survey on human-centric communication
challenges and solutions in the non-cooperative WRNs that focuses on: (1) an
overview of the non-cooperative WRNs and introduction to various types of node
selfish and malicious behaviors, (2) the impact analysis of node selfish and
malicious behaviors on the performance of data forwarding and distribution, (3)
selfish and malicious node detection and defense systems, and (4) incentive
mechanisms. Finally, we discuss several open problems and future research
challenges.
