Using two-hop neighborhood information, we develop fourapproaches for time-division channel access scheduling in adhoc networks with omni-directional antennas, which are derivedfrom a novel approach to contention resolution that allows agroup of contenders to elect deterministically one or multiplewinners in a given contention context (e.g., a time slot). Exceptfor the node activation multiple access (NAMA) which schedulescommunications through a single channel, the link activation...
