Maximum Throughput and Minimum Delay in IEEE 802.15.4: Paper

This paper investigates the maximum throughput and minimum delay of the new IEEE 802.15.4-standard. This standard was designed as a highly reliable and low-power protocol working at a low data rate and offers a beaconed and unbeaconed version. We will give the exact formulae for a transmission between one sender and one receiver for the unbeaconed version as this one has the least overhead. Further, the influence of the different address schemes, that is, no addresses or the use of long and short addresses, is investigated. It is shown that the maximum throughput is not higher than 163 kbps when no addresses are used and that the maximum throughput drops when the other address schemes are used. Finally, we will measure the throughput experimentally in order to validate our theoretical analysis.

The market of wireless devices has experienced a significant boost in the last few years, and new applications are emerging rapidly. Several new protocols have been proposed such as IEEE 802.11g and IEEE 802.16. However, these protocols focus on achieving higher data rates in order to support high bit rate applications for as many users as possible. On the other hand, there is a growing need for low data rate solutions which provide high reliability for activities such as controlling and monitoring. Furthermore, these applications often use simple devices which are not capable of handling complex protocols. In order to cope with this problem, a new standard was defined in the end of 2003: IEEE 802.15.4.
