Ing-Ray Chen – with U.S. Army Research Laboratory (ARL) collaborators Jin-Hee Cho and Ananthram Swam -- has received the Army Research Laboratory 2016 Publication Award.

This honor recognizes the authors’ outstanding contribution, “A Survey of Trust Management for Mobile Ad Hoc Networks.”

Managing trust 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, and reconfigurability. In defining and managing trust in a military MANET, it is a must to 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, node mobility, node failure, propagation channel conditions).

In their survey, Chen, Cho, and Swam discuss generally accepted classifications, potential attacks, performance metrics, and trust metrics in MANETs and properties of trust. And they discover some unique characteristics of trust in MANETs by combining the notions of "social trust" derived from social networks with "quality-of-service (QoS) trust" derived from information and communication networks in order to obtain a composite trust metric.

They also discuss future research areas on trust management in MANETs based on the concept of social and cognitive networks.

Chen is a professor and director of the Department of Computer Science in the National Capital Region. His research interests are in mobile and pervasive computing, sensor networks, trust and security, data management, reliability and performance analysis, and real-time intelligent systems.

Cho received both her masters and doctoral degrees in computer science from Virginia Tech.
