Implementation of a WSNet Module to Simulate the IEEE 802.15.4 Beacon-Enabled Mode in Multihop Topologies

In this paper, the authors describe their implementation of the beacon-enabled mode in IEEE 802.15.4. They implemented both the Beacon-Only Period (BOP) and the superframe scheduling techniques to support multihop topologies. These techniques permit to reduce the number of collisions, and they implemented very simple collision avoidance scheduling. This implementation works with the wsnet simulator. IEEE 802.15.4 details a norm for inter-connecting low-power sensors and actuators. IEEE 802.15.4 is expected to be deployed for e.g. house automation and many other applications. Zigbee extends IEEE 802.15.4 by describing associated routing and application layer functions.
