Abstract-- Security issues and attack management in transparent WDM (Wavelength Division Multiplexing) optical networks has become of prime importance to network operators due to t...
—In wireless sensor networks, sensor nodes are expected to gather specific information about the environment and send it to the user. The data dissemination usually involves many...
Hierarchical routing is a promising approach for point-topoint routing with very small routing state. While there are many theoretical analyses and high-level simulations demonstr...
