Resilience is arguably the most important property of a networked system, one of the three quality of service (QoS) characteristics along with security and performance. Now that computer networks are supporting many of the applications crucial to the success of the emerging Information Society – including business, health care, education, science, and government – it is particularly important t...

Wireless Mesh Networks are an increasingly common technology providing connectivity in many communities, particularly where Internet access is unavailable or restricted via more conventional means. Their comparative ease of installation and relatively low cost makes this especially true for communities which might previously have lacked the technical knowledge or skill to attempt such an endeav...

Resilience has become a key aspect in the design of contemporary infrastructure networks. This comes as a result of ever-increasing loads, limited physical capacity, and fast-growing levels of interconnectedness and complexity due to the recent technological advancements. The problem has motivated a considerable amount of research within the last few years, particularly focused on the dynamical...

We investigate the protection of network elements with non-simple p-cycles. We present four types of non-simple cycles; discuss the characteristics of non-simple cycles and present basic examples when and where non-simple cycles have an advantage compared to the protection with elementary cycles only. We develop a combined mathematical formulation for the routing and p-cycle optimization proces...

This paper makes the case for Resilient Overlay Networks (RONs), an application-level routing and packet forwarding service that gives end-hosts and applications the ability to take advantage of network paths that traditional Internet routing cannot make use of, thereby improving their end-to-end reliability and performance. Using RON, nodes participating in a distributed Internet application c...

The IEEE 802.11 is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN). The protocol was designed with the implicit assumptions that nodes would always follow the protocol rules and regulations. There was no provision to check for compliance with these rules, neither was there any provision to enforce such compliance. C...

This paper describes, briefly, ongoing research on resource reservation state management, including research motivations and initial design.

1. Introduction: Wireless sensor-actuator networks (WSAN) are cyber-physical systems (CPS) consisting of numerous sensing and actuation devices sharing information over a wireless communication network. This project studies resilient WSANs where " resilience " means that the system maintains an awareness of surrounding threats while taking actions assuring a return to operational normalcy as qu...
