Using commercial tranceivers to build a wireless network

Abstract

This thesis implements a wireless network based on Pure Aloha protocol for smarthouse application. The network includes three nodes with one master, two slaves. Each node includes the HM-TR transparent wireless data link module, beside, the master is controlled by a computer program, and the slaves are controlled by Atmega32 microcontrollers. This network simulates an indoor managing system which is applied on door accessing. The two slaves in role of doors send request access to the master. The master compares the receiving request and sends the controlling commands.
