Distributed Duty Cycle Management (DDCM) for IEEE 802.15.4 Beacon-Enabled Wireless Mesh Sensor Networks
This paper proposes an extension to the current IEEE802.15.4 standard in which flexible mesh networking in the low power beacon mode is enabled through the use of a distributed Duty Cycle Management (DDCM) strategy in conjunction with a Distributed Time Beacon Scheduling (DTBS) technique. The DTBS technique enables a beacon enabled coordinator to calculate its time schedule to transmit beacons, thus avoiding potential collisions, without the need of a central coordinator. The proposed DDCM strategy is able to reconfigure, in an IEEE802.15.4 beacon-enabled wireless mesh sensor network, nodes' duty cycle based only on locally available network information.
