Recent advances in optical communications have increased the bandwidth of individual wavelengths and the number of wavelengths carried per fiber by a substantial amount. The increase in traffic demands has however failed to keep pace with this phenomenon resulting in a number of sub-wavelength demands. These sub-wavelength demands need to be allocated one wavelength resulting in wastage of resi...

Large-scale failures triggered by undesirable events such as natural disasters, massive power malfunction, and malicious attacks are attracting serious concerns in communication network infrastructure perspective. However, there have been few survivability strategy analyses in network mobility (NEMO) scenarios. To properly address this issue, this paper proposes two novel survivability strategi...

MITRE’s Evolvable Real-Time C3 (Command, Control, and Communications) project has developed an approach that would enable current real-time systems to evolve into the systems of the future. This paper first summarizes the design and implementation of an infrastructure for an evolvable real-time C3 system. Then, a detailed discussion of the infrastructure requirements for a survivable real-time ...

Reliability and security are two major criteria for survivable communications in error-prone wireless environments. To ensure reliable communications, Forward Error Correcting (FEC) codes such as Reed-Solomon (RS) codes are employed for error detection and correction by adding redundancies into the original data to form code words. Secure data communications based on FEC are achieved in many tr...

Wireless mobile networks have become crucial in providing untethered communication services to mobile users. In this paper, we propose an optimization model for the design of survivable wireless access networks. The main objective of the model is to optimize the network design cost of wireless backhaul networks while meeting survivability requirements. This paper also presents a simple and effi...

This document surveys several of the profound technical problems and challenges faced by practitioners in the assembly and integration of secure and survivable systems.

BACKGROUND Studies of the epidemiology of deaths from violent causes can provide valuable information for the treatment of traumas. We wished to ascertain whether the victims had survivable injuries and were accessible for treatment at the time of discovery of the injury. The purpose was to identify areas of intervention that may help save lives. MATERIAL AND METHOD An overview of deaths from...
