— We consider the problem of energy efficient random deployment of sensor network. Our goal is to find the sensor node density, or alternatively, the energy resource density at e...
The wireless sensor network based localization system—Cicada is designed to support the locationawareness in indoor environment. The system is based on TDOA (time difference of ...
This paper investigates a class of mobile wireless sensor networks that are unconnected most of the times; we refer to them as delay–tolerant wireless sensor networks (DTWSN). T...
