Simulation Results

To solve the beacon collision problem in IEEE 802.15.4/ZigBee cluster-tree Wireless Sensor Networks, we proposed a Sequential Beacon Scheduling (SBS) mechanism. In this mechanism, the Cluster Headers (CHs) choose the beacon transmission time in a certain order. The CH which finishes the sequence chosen sends out control frame to inform other CHs in its interference range. The simulation results indicate that SBS general has better delivery ratio, latency, and throughput than three other beacon scheduling mechanisms.
