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 ...

To increase the lifetime of the sensor networks, a recognized method is to switch off/on some sensor nodes between “sleep” and “activity” mode in order to save the energy....
We present a deterministic Key Predistribution scheme in Wireless Sensor Networks (WSN) using combinatorial designs. The design finds application where a large number sensor node...
This paper exploits the tradeoff between data quality and energy consumption to extend the lifetime of wireless sensor networks. To obtain an aggregate form of sensor data with pre...
In this paper, we investigate the theoretical aspects of the nonuniform node distribution strategy used to mitigate the energy hole problem in wireless sensor networks (WSNs). We c...
