Abstract
Ad hoc wireless sensor network's (AHWSN) primary goal is energy efficiency. Theoretically, the most energy efficient MAC protocol for a mesh network would be a TDMA based protocol without the administration, control and exact timing signals that needs to be conveyed. This paper presents a hardware solution and a TDMA MAC protocol that is as close to that ideal as possible. The proposal is a low power hardware mailbox that enables nodes to catch messages destined for them while they are asleep. This also allows lee-way to the exact timing of the synchronisation needed for a TDMA scheme. In addition the protocol reduces the amount of control messages that needs to be transmitted between nodes and also defines how the nodes need not change their function and role periodically, to coordinate the transmissions of data of other nodes.
