ZLeAp: Application for Wireless Sensor Network (ZigBee) learning tool

ZLeAp is a Wireless Sensor Network (WSN) learning aid application based on ZigBee. This application is intended to assists academics in the study of ZigBee devices, especially in terms of the formation of message delivery route. This application shows the real route generated from the hardware unlike the other simulation tools which generates the route based on specific algorithm and pre-generated conditions. ZLeAp provides seven learning scenarios. The scenarios are three routing learning scenarios, two scenarios for the effect of transmission power, and two timing constraints scenarios. It is known that ZigBee devices are smart devices that are trying to choose the best route with the lowest cost and the routes are able to change dynamically. The experiments shows that the shorter distance between devices doesn´t always produces lower cost compare to the longer ones. The transmission power plays significant rule in routing but the routing results is not always the same as theoretical route. Network resolving time depends on network size and beacon periods. During the design of WSN this time value should be anticipated.
