Systems and methods for throughput enhancement including asynchronous neighbor discovery among ultra-low power wireless network devices are provided. Specifically, techniques for discovering neighboring wireless devices within an energy-harvesting and/or energy constrained wireless communication network are provided such that the wireless devices are able to discover the greatest number of neighboring devices without exceeding the energy that they have accumulated by, for example, harvesting ambient sources or their allocated energy budget (e.g., battery/capacitor levels). Such devices are capable of transmitting and receiving data such as discovery messages and alternate between different operation states (e.g., listen, sleep, transmit) and are able to compute transitions rates in a centralized and/or distributed manner using either homogeneous or heterogeneous wireless devices.

Systems and methods for throughput enhancement among ultra-low power wireless network devices

An optical communication system includes a plurality of optical system nodes, a plurality of optical space switches and a plurality of optical fibers. The plurality of optical system nodes each includes at least one reconfigurable optical add/drop multiplexer (ROADM). The optical system nodes each have at least one client side port and at least one line side port. Each optical space switch is operatively coupled to the line side port of one of the plurality of optical system nodes. Each of the optical fibers couples one of the optical space switches to another of the optical space switches.

Resilient optical networking

A method, computer-readable storage device, and apparatus for allocating a plurality of timeslots of each channel of a plurality of channels in a wireless network are disclosed. For example, the method determines a location and a velocity for each user endpoint device of a plurality of user endpoint devices, estimates a future data rate for each user endpoint device at the location, estimates future timeslot allocations of each channel of the plurality of channels in the wireless network in accordance with the future data rate that is predicted for each user endpoint device, and allocates each timeslot of the plurality of timeslots of each channel of the plurality of channels in the wireless network to a user endpoint device of the plurality of user endpoint devices in accordance with the future timeslot allocations that are estimated for each channel.
