1. A method for scheduling the transmission of packets in a configurable, Time Division, Multiple Access (TDMA) wireless network that ensures both bandwidth and delay Quality-of-Service (QoS) guarantees comprising:
- dividing a time period into one or more superframes, each superframe consisting of a plurality of slots, each slot having a duration substantially equal to the time required to transmit a single packet; and
generating a packet transmission schedule for one or more wireless stations in the TDMA network such that only a single packet is transmitted during each slot assigned to each of the one or more stations to reduce collisions between transmitted packets.

Abstract
A more energy efficient, medium access control (MAC) layer of a multi-hop wireless network is provided using scheduling techniques which reduce packet collisions, and therefore the need for packet re-transmissions, while ensuring both bandwidth and delay, Quality-of-Service (QoS) guarantees. The techniques are used in conjunction with the formation of a multi-hop, configurable access wireless network (CAN).
