The vast majority of combat casualties who die from their injuries do so prior to reaching a medical treatment facility. Although most of these deaths result from nonsurvivable injuries, efforts to mitigate combat deaths can still be directed toward primary prevention through modification of techniques, tactics, and procedures and secondary prevention through improvement and use of personal pro...

Survivable systems software must exhibit high resistance to intrusion. A process of stochastic diversification can help increase resistance to intrusion through random obscuration of survivable system properties. Intruders often rely on analysis of source code to identify and exploit vulnerabilities in software. The ability of intruders to understand and analyze code can be dramatically reduced...

This paper was concerned with the problem of designing a survivable multicommodity network with node capacities, which is about selecting a set of fixed-charge arcs in order to build a survivable network with minimum cost and satisfied flow requirements. The system is subject to failure and capacity restriction. Failure is defined as simultaneous failure of arcs. To solve the problem, first, a ...

Telecommunication networks can be seen as the stacking of several layers like, for instance, IPover-Optical networks. This infrastructure has to be sufficiently survivable to restore the traffic in the event of a failure. Moreover, it should have adequate capacities so that the demands can be routed between the origin-destinations. In this paper we consider the Multilayer Capacitated Survivable...

Compared with traditional WDM network, OFDM-based flexible optical networks are able to provide better spectral efficiency due to its flexible allocation of requests on finer granularity subcarriers. Survivability is a crucial issue in OFDM-based networks, although little work has been done in this topic. In this thesis, a survivable multipath provisioning scheme is presented, which provides fl...

Given a weighted undirected graphGwith a set of pairs of terminals {si, ti}, i = 1, ..., d, and an integer L ≥ 2, the two node-disjoint hop-constrained survivable network design problem (TNHNDP) is to find a minimum weight subgraph of G such that between every si and ti there exist at least two node-disjoint paths of length at most L. This problem has applications to the design of survivable te...

Recent development in optical networking employing wavelength-division-multiplexing (WDM) fulfills the high bandwidth demand applications. Failure of such networks, leads to enormous data and revenue loss. Design a low cost survivable WDM network is always an interesting and difficult process. In this paper we present link-path model for capacity allocation and calculate blocking probability in...
