While extensive studies have been carried out in the past several years for many sensor applications, they cannot be applied to the network with extremely low and intermittent con...
—This paper presents a cooperative single-input multiple-output (SIMO) transmission scheme for wireless sensor networks (WSNs), where the number of antennas and the constellation...
The lifetime of wireless sensor network is crucial, since autonomous operation must be guaranteed over an extended period. As all the sensor data has to be forwarded to an observe...
Energy consumption is the most important factor that determines sensor node lifetime. The optimization of wireless sensor network lifetime targets not only the reduction of energy...

We consider a wireless sensor network in which sensors are grouped into clusters, each with its own cluster head (CH). Each CH collects data from sensors in its cluster and relays...
