Parallel interaction medium access for wireless ad hoc networks


Veyseh, M.; Garcia-Luna-Aceves, J. J. Parallel interaction medium access for wireless ad hoc networks. 17th International IEEE Conference on Computer Communications and Networks (ICCCN 2008); 2008 August 3-7; St. Thomas, US Virgin Islands.


The Parallel Interaction Medium Access (PIMA) protocol is introduced to orchestrate channel access in a wireless ad hoc network when nodes are endowed with a single half-duplex radio, and can either transmit multiple packets to multiple destinations in parallel or receive multiple packets from multiple transmitters in parallel using OFDMA. Analytical and simulation results indicate that PIMA attains tremendous improvements in channel throughput compared to MAC protocols aimed at attaining concurrency via traditional channel switching techniques proposed in the past for multi-channel networks.
