能源效率和网络寿命是无线传感器网络的主要问题。为了改善这些因素，ZigBee发挥了重要作用。ZigBee具有低成本、低数据速率的特点，因此功耗低，在无线传感器网络中非常有用，增加了网络中节点小型电池的寿命。由于ZigBee中的树路由不需要任何路由表将数据包发送到目的地，因此可以在资源有限的ZigBee终端设备中使用。AODV （Ad-hoc随需应变距离矢量路由）、ZTR （ZigBee树路由）和STR（捷径树路由）等路由协议根据不同的性能指标（端到端延迟、路由过载、吞吐量、包投递率）进行了比较。在NS2中进行了广泛的仿真。性能评估表明，与其他两种路由协议相比，STR实现了更好的性能。但是，STR方法也有一些局限性。与AODV相比，STR的包投递率性能较差。与AODV相比，STR的端到端延迟性能较差。因此提出了ESTR。提出的ESTR [Extended STR]的主要目的是提出新的ZigBee网络路由协议，以提高ESTR在PDR和抗STR和AODV延迟方面的性能。
Energy efficiency and network lifetime are main concerns in WSN. In order to improve these factors ZigBee plays an important role. Low cost, low data rate features of ZigBee results in low power consumption and makes it useful in wireless sensor networks, increasing life of small batteries of nodes in the network. Since tree routing in ZigBee does not require any routing tables to send the packet to the destination, it can be used in ZigBee end devices that have limited resources. Routing protocols such as AODV (Ad-hoc on demand distance vector routing), ZTR (ZigBee tree routing), and STR (Shortcut tree routing) are compared on the basis of different performance metrics (End to end delay, routing overload, throughput, packet delivery ratio). An extensive simulation in NS2 is carried out. The performance evaluation shows that STR achieves better performance as compared to other two routing protocols. But there are some limitations of the STR method. Performance of packet delivery ratio of STR is less as compared to AODV. Performance of end to end delay of STR is poor as compared to AODV. Hence ESTR is proposed. The main aim of proposed ESTR [Extended STR] is to present new ZigBee network routing protocol with goal of improving the performance of ESTR in terms of PDR and delay against STR and AODV.
