Sensor nodes are often used to collect data from locations inaccessible or hazardous for humans. As they are not under normal supervision, these nodes are particularly susceptible...
—Existing methods of measuring lifetimes in P2P systems usually rely on the so-called Create-Based Method (CBM) [16], which divides a given observation window into two halves and...
Recent technological advances have opened up several distributed real-time applications involving battery-driven embedded devices with local processing and wireless communication ...
– In contrast to a typical single source of data updates in Internet applications, data files in a networked information system are often distributed, replicated, accessed and up...
— We consider a network of rechargeable sensors, deployed redundantly in a random sensing environment, and address the problem of how sensor nodes should be activated dynamically...
