Keywords: Underwater electromagnetic communications Underwater wireless sensor networks TDMA a b s t r a c t Very low frequency electromagnetic communication system is used in a small scale underwater wireless sensor network for coastal monitoring purposes, as recent research has demonstrated distinct advantages of radio waves compared to acoustic and(More)
A star-topology local area network is designed to carry optical packet traffic, employing collision-free switching. Data forwarding is under centralized control based on scheduled resource reservation, eliminating the need for optical buffers in the central switch. Packets are stored in electronic buffers within the end stations prior to their(More)
An access network protocol running optical packet switching traffic is designed to optimize the resource allocation and buffer management. The deployment of edge electronic buffer and the scheduling in advance illuminate the limitations of dense wavelength division multiplexing (DWDM) and avoid the complexity and expense problems that usual optical(More)
