    We study the optimal survivability design problem under a scheduled traffic model in wavelength convertible WDM optical mesh networks. In this model, a set of demands is given, and the setup time and teardown time of a demand are known in advance. We formulate the joint routing and wavelength assignment problems as integer linear programs that maximally exploit network resource reuse in both space... View full abstract»

    For optical communication networks, the wavelength division multiple access (WDMA) system has been developed at first and maturely commercialized. Although WDMA can be used to satisfy the requirement mentioned above, it has the disadvantage of low efficiency in utilizing bandwidth (for the high bandwidth optical communication system). Thus, the optical code division multiple access (OCDMA) is deve... View full abstract»

    Ad-hoc networks rely on participation and cooperation of nodes within the network to transmit data to destinations. However, in networks where participating nodes are controlled by different owners, nodes may choose to act in their own interest to the detriment of the network. Current solutions either exact high overheads on the network and nodes, or only operate in specialized scenarios and preve... View full abstract»
