Hi Wang, I dont know any authoritative definition for the lifetime of a network. But in my opinion is that depends on the application/scenario. Some authors claim that it is the time till the last/first node is alive/dead, or even half network is dead. But i guess that it is important to register the time when the network is no longer performing its goal, this meatric can be a % of monitored phenomenos.
