Intention Sharing for Medium Access Control in Wireless LANs

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

In this paper we present a new class of MAC protocols for
wireless LANs based on sharing of transmission intentions.
We develop an example protocol implementation based on
distributed, co-operative scheduling of data frames. Sched-
ules are non-binding, requiring minimal negotiation between
nodes. The protocol is implemented on top of standard
802.11 so that backwards compatibility with legacy nodes is
maintained. We have developed efficient algorithms to merge
multiple schedules from neighbouring nodes and find suitable
gaps in which to schedule a given node’s frames. To test the
protocol’s performance, we conducted simulation studies us-
ing OMNeT++. Our results show that our protocol achieves
higher throughput and lower delay than 802.11 under high
offered loads, and eliminates frame collisions.
