Lovish Jaiswal, Jaswinder Kaur, Gurjeevan Singh · 2012
ZigBee (IEEE 802.15.4-2006 standard) is a category in the IEEE 802 family, along with some of the well-known protocols such as Wi-Fi, Bluetooth which uses the 2.4 GHz industrial, and scientific and medical (ISM) radio band. ZigBee also utilizes 868 MHz and 915 MHz in different parts of the world according to local standards. Unlike Wi-Fi and Bluetooth, ZigBee was developed for low-rate WPAN (LR-WPAN) which feature long battery life by having low data rates. In ZigBee WSN’s, topology plays an important role and is one of the most significant parameter in Wireless Sensor Networks. In this paper we evaluate the effect of topologies variation i.e. Tree, Star and Mesh on throughput, end to end delay, number of hop and network load using ZigBee wireless sensors by means of OPNET modeller 14.5. technologies will be a significant one, especially as reliability is an important requirement. There are three main nodes used in
