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...

Reliable Networks with Unreliable Sensors
Abstract. Wireless sensor networks (WSNs) deployed in hostile environments suffer from a high rate of node failure. We investigate the effect of such failure rate on network conn...
