Abstract:
1. A method of multiple packet reception (MPR) using distributed time slot assignment (DTSA) in a multi-user network where receivers can detect two packets at the same time, comprising: requesting information on slot assignment in a contention area by a new node, including information on MPR slots which are taken with two neighbors; setting a frame length and taking a slot assignment, where the new node makes a list of time slots that are MPR slots from the neighbors' point of view; selecting an assigned slot by: after assigning a slot to itself, the new node sends a suggestion (SUG) packet to its neighbors which has the information about the frame length and the assigned slots; after receiving the SUG packet, each neighbor updates its time slot assignment and changes its frame length accordingly; sending a reply (REP) packet from each neighbor to their neighbors; if the new node connects two or more nodes that are assigned to the same timeslot, the new node resolves the conflict by: exiting the control mode for all neighbors of the new node.
