“…Thus, higher priority flows start transmitting earlier, without contending with lower priority traffic. This results in an absolute traffic prioritization, similar to some priority schemes used in IEEE 802.11 ad hoc networks [15]. The duration of each priority slot, PRI SLOT, is 21 s. Stations must transmit their frames at the beginning of a slot whose number is equal to or less than the frame priority.…”

This paper proposes a new mechanism to increase the HomePNA 2.0 MAC protocol throughput. First, we review the HomePNA MAC protocol and its collision resolution mechanism. Then, we use simulations to evaluate the throughput of HomePNA using a module that we implemented in the ns-2 simulator. We propose a priority aggregation mechanism that uses the 8 HomePNA priority levels in a more efficient way. The simulation results show that the proposed mechanism is able to increase the throughput up to 44%. Moreover, our mechanism does not require modifying the HomePNA specification, and can be easily implemented as a new sublayer above the MAC sublayer.
