Model-Based Design Exploration of Wireless Sensor Node Lifetimes
Lecture Notes in Computer Science
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 hardware parameters such as power consumption per task, state transition overheads, and communication cost to compute a node's average lifetime for a given event arrival rate. Through comparison of the two models and a case study from a real camera sensor node design we show how the models can be applied to drivedoi:10.1007/978-3-540-69830-2_18 dblp:conf/ewsn/JungTBS07 fatcat:4rb7yneyvjfcrdxdii4uknpwry
