Because of their fast and economically less-demanding deployment, wireless ad hoc network applications are found in various areas, including military applications, emergency operations, and collaborative and distributed computing. This type of network should be able to stay connected under misbehaviors and failures, in order to fulfill its task in a timely manner. In this context, survivability has received a lot of attention, and this paper proposes an alternative solution to this important research direction.

The main contribution is the development of a “framework to study the impact of node misbehaviors and failures on network survivability.” In addition, it provides “a quantitative analysis on the impacts of both node misbehavior and failure on network survivability.” More precisely, the authors consider the “survivability of a wireless ad hoc network as the probabilistic k-connectivity [of individual nodes].” Sections 5 and 6, “Network Survivability Analysis” and “Scenario Study and Simulation Results,” provide a good understanding of the developed scenario.

The overall effort invested in the paper achieves the intended goal stated in Section 2, “Problem Formulation.” I recommend this work to researchers in the fields of fault-tolerant networks in particular and network security in general.
