Wireless Sensor Network could be implemented as a communication technology for sensory devices. In WSN applications such as homes, hospitals, clinics and other industrial areas, the number of wireless sensor devices continues to increase. End to end delay of packets, loss of packets, packets collision and bandwidth are some of the major issues experienced in WSNs. In this study, ZigBee routing protocols are studied and analysed. High network latency is identified as one of the shortcomings of ZigBee Tree Routing protocol. This shortcoming is caused by the end-to-end delay of packets as they are routed on a Tree topology. In response to this shortcoming, this study will propose an algorithm that attempts to improve the original ZigBee Tree Routing protocol. New Tree Routing Protocol (NTRP) is an output of merging ZigBee Tree Routing algorithm and Kruskal's Minimum Spanning Tree Protocol. NS-2 simulator will be used to validate the proposed algorithm.
