Abstract	IEEE 802.15.4 is a promising standard for MAC and physical layer of Wireless Sensor Networks. Recently, Wireless Sensor Network has developed into a highly used protocol to transmit multimedia data, such as voice, image and video. Since these data types have high volume, throughput and delay would be significant parameters in these networks. IEEE 802.15.4 supports only Star and Cluster Tree Topologies and does not support mesh topology in Beacon-Enable mode. In this paper, a Load-Adaptive Beacon Scheduling (LABS) approach is proposed to enable mesh topology over IEEE 802.15.4 Beacon-Enable mode. MeshMAC and BOP approaches have been proposed for scheduling of IEEE 802.15.4, but they do not consider throughput for supporting Quality of Service of multimedia data. Our work is inspired from MeshMAC, although LABS approach enhances throughput and alleviate end to end delay in high congested region in comparison with MeshMAC approaches. The proposed approach is simulated by NS-2 simulator which will confirm the results.
