Abstract:
Zigbee/IEEE 802.15.4 is a high level communication and short range standard in Wireless Sensor Networks (WSN), where each node can send and receive data with high security, reliability, low complexity, low power consumption and low cost. It is utilized by industry leaders, such as Samsung, Motorola, Siemens, Philips, etc., and used in industrial, medi-cal purposes, control and monitoring applications. ZigBee supports two operation modes; beacon enabled mode and bea-conless enabled mode. In this paper, we present the optimal values of two parameters used in the Zigbee standard, name-ly, BO (Beacon Order) and SO (Superframe Order), to en-hance the network performance, which can be obtained by increasing the network throughput as well as decreasing the total energy consumption and end-to-end delay. The experi-ment was applied on a star topology, along with an improved backoff mechanism for ZigBee networks. The results showed that the best BO and SO values that increases the throughput, decreases the end-to-end delay as well as decreases the total energy consumption is (8, 8).
