Towards Trust-based Cognitive Networks: A Survey of Trust Management for Mobile Ad Hoc Networks
Jin-Hee Cho, Ananthram Swami · 2009
Abstract : Managing in a distributed Mobile Ad Hoc Network (MANET) is challenging when collaboration or cooperation is critical to achieving mission and system goals such as reliability, availability, scalability, or reconfigurability. In defining and managing in a military MANET, we must consider the interactions between the composite cognitive, social, information and communication networks, and take into account the severe resource constraints (e.g., computing power, energy, bandwidth, time), and dynamics (e.g., topology changes, mobility, node failure, propagation channel conditions) in a military MANET. We seek to combine notions of trust derived from social networks with quality-of-service (QoS) trust derived from communication networks to obtain a composite metric. We will discuss the concept and properties of and derive some unique characteristics of in MANETs, drawing upon social notions of trust. We will give a survey of management schemes developed for MANETs and will discuss generally accepted classifications, potential attacks, and metrics in MANETs. Finally, we will suggest future research directions on management in MANETs based on the concept of social and cognitive networks.
