On distributed fault-tolerant detection in wireless sensor networks
TL;DR: This work proposes a fault-tolerant detection scheme that explicitly introduces the sensor fault probability into the optimal event detection process and mathematically shows that the optimal detection error decreases exponentially with the increase of the neighborhood size.

Relay node placement in large scale wireless sensor networks
Jian Tang,Bin Hao,Arunabha Sen +2 more
TL;DR: This paper formulate the relay node placement in wireless sensor networks as two optimization problems: (i) Connected Relay Node Single Cover (CRNSC) problem and (ii) 2-Connected Relays Node Double Cover (2CRNDC) problem, and presents two polynomial time approximation algorithms to solve the CRNSC problem.
