Survivability Evaluation for MANET Based on Path Reliability

The survivability evaluation of MANET includes many metrics. Among them, path reliability is the fundamental one. However, most existing work on it has focused either on connectivity or the link duration time solely. Due to the special features of MANET, the radio coverage and node energy also have high effluence on the reliability of the path. Usually, tradeoffs should be considered among these features to obtain the largest survivability. So, this paper presents a survivability model that integrates these metrics together and evaluates the MANET survivability fairly. Simulation shows how the individual metric or the total metrics affect the survivability of MANET. This paper also points out that the proposed analytical method can evaluate the survivability of MANET fairly well.
