Many applications require a lifetime of several years from a sensor network while expecting low and guaranteed end-to-end delays between sources and a sink. Obviously, these two parameters - lifetime and delay - contradict each other. In this work we present and evaluate a solution that limits the end-to-end delays and nevertheless achieves a long lifetime. We introduce a model for evaluation of delay and lifetime in multi-hop sensor networks. According to our model a network of off-the-shelf sensor nodes limits an end-to-end delay to 5 seconds and works for 8 months. However, if applications can tolerate the end-to-end delay of 20 seconds, the nodes prolong the lifetime to approx. 2 years. Our evaluation revealed that end-to-end delay affects the lifetime only to a certain limit. In our example this limit was 60 seconds, i.e. any delay change above 60 seconds does not influence the lifetime considerably.
