Traditionally, a packet with errors, either due to channel noise or collisions, is discarded and needs to be retransmitted, leading to performance losses. Network Diversity Multiple Access (NDMA) handles collisions by combining a multipacket detection scheme with time diversity. In NDMA, the base station (BS) forces mobile terminals (MTs) to transmit J(More)
— DTIA (Dynamic Topological Information Architecture), an inter-domain routing architecture, assumed the existence of " regions of domains " to offer a scalable solution for the Internet. The way regions can be connected and how traffic flow amongst them is not a trivial aspect and can jeopardize the solution proposed for intra-region traffic. This paper(More)
Traditionally, a packet with errors, either due to channel noise or collisions, is discarded and needs to be retransmitted, leading to performance losses. Hybrid Automatic Retransmission reQuest (H-ARQ) and time diversity multipacket reception approaches, such as Network Diversity Multiple Access(NDMA), improve the system performance by requesting(More)
