An Enhanced Routing Protocol for ZigBee/IEEE 802.15.4 Wireless Networks

ZigBee is a well accepted industrial standard for wireless sensor networks based on IEEE 802.15.4. Since aiming for the application of low data rate, low price and low power consumption, ZigBee networks have the limited resources such as computation complexity and storage space. So it is especially important to design an efficient and effective routing protocol to save the consuming energy and extend the lifetime for ZigBee networks. In this paper, we survey two kinds of routing methods of the existing ZigBee routing protocol, and then propose two improved algorithms respectively. Simulation results show that the proposed routing version is a more efficient routing protocol, which can reduce routing overhead and routing discovery delay.
