An asynchronous medium access control layer scheduler increases efficiency for directional mesh networks by removing extra overhead in the time slots. The efficiency is increased by dividing time slots into sub-slots to allow for a receiving node to be offset by at least one sub-slot from the transmitting node. This enables the scheduler to more efficiently schedule operations for the nodes so that nodes can be performing other functions rather than waiting to receive a transmission or waiting after transmitting a transmission. The sub-slots may be sized to approximate the transmission propagation time or time of flight delay.

Asynchronous medium access control layer scheduler for directional networks

A set of methods for discovery of nodes where at least some of the nodes use directional antennas is presented. The methods consist primarily of partitioning the search space into tiers based on elevation angles and adjusting parameters used to construct tiling patterns and slots for discovery messaging, and search methods patterns. The methods further include partitioning into subslots as well as characterization of HAIL slots and rendezvous slots. The HAIL slots and rendezvous slots are allocated within a search schedule and synched across multiple platforms for greater efficiency of communication.
