In the harsh environment where node density is sparse, the slow-moving nodes cannot effectively utilize the encountering opportunities to realize the self-organized identity authentications, and do not have the chance to join the network routing. However, considering most of the communications in opportunistic networks are caused by forwarding operations, there is no need to establish […]
Read moreIn this paper, we consider the problem of distributed parameter estimation in imperfect environments for wireless sensor networks (WSNs). By imperfect environments, we refer to distortions that can be caused by sensor noise, quantization noise and channel effect. A novel statistical model is proposed to quantify these errors in WSNs. The first and second order […]
Read moreOptical networks-on-chip (ONoCs) have shown the potential to be substituted for electronic networks-on-chip (NoCs) to bring substantially higher bandwidth and more efficient power consumption in both onand off-chip communication. However, basic optical devices, which are the key components in constructing ONoCs, experience inevitable crosstalk noise and power loss; the crosstalk noise from the basic devices […]
