How Long is the Lifetime of a Wireless Sensor Network?
Wireless sensor networks (WSNs) are known to be highly energy-constrained and each network’s lifetime has a strong dependence on the nodes’ battery capacity. As such, the netw...

Model-Based Design Exploration of Wireless Sensor Node Lifetimes
This paper presents two lifetime models that describe two of the most common modes of operation of sensor nodes today, triggerdriven and duty-cycle driven. The models use a set of ...
