N2 - The advancement of the self-forming, multi-hop Mobile Ad-hoc Wireless Networks (MAWN) created the need for new analysis methods which enable the accurate determination of the reliability and availability of these networked systems. Accordingly, a set of new and innovative methods has been developed and further research is on-going. The need for these methods is because contrary to hardwired networks, the MAWN is a scalable network without infrastructure. Along this line, the MAWN's configuration forms dynamically and probabilistically and as such no singular graphical depiction or mathematical function is able to describe its reliability. It is this feature that precludes the use of traditional methods. These new analytical methods are progressing in parallel with the proliferation of this technology so that reliable performance may be realized. Due to its flexibility, this new network scheme is often deployed in critical applications such as military and first responder applications. In such cases, reliability becomes a paramount system attribute. The primary contribution of this method is to describe and summarize the published methods in a single location. Taken together the tools are now available to a practitioner to analyze and optimize MAWN reliability. Mostly, this work is motivated by the application of MAWN technology in the DoD tactical networks and the import of their reliable operation when employed for this use. Throughout the chapter, DoD network examples will be used to demonstrate the reliability methods developed for the MAWN. The methods include both closed form analysis and Monte Carlo simulation techniques to establish terminal-pair reliability of the MAWN under a random waypoint mobility model; the metrics include two-terminal, k-terminal, and allterminal reliability.
