摘要: In this paper we consider the problem of identifying faulty (crashed) nodes in a wireless sensor network. This is fundamental importance those applicative scenarios networks which battery replacement feasible. The diagnostic information gathered by operational sensors can be used an external operator for sake network reconfiguration and/or repair; thus extending lifetime. A fault diagnosis protocol specifically designed introduced and analyzed. proved to optimal energy efficient under certain assumptions.
