Design of 32 Nodes Wireless Sensor Network Through Mesh Networking for Industrial and Residential Security

Abstract

Industrial and residential security maintenance is one of the major safety concerns for counteracting any unwanted activities. It is not only for protecting the expensive equipment but also for avoiding any hazardous situations. Therefore, the security system has to be robust, dependable and well configured. Retaining these standards, a 32 nodes Wireless  sensor security network has been proposed in this paper. The nodes are placed on the glass windows surrounding the floors. Each node consists of a sensor to recognize any cracking sound on the glass by detecting the frequency of it. The Passive Infrared sensor on the nodes can detect any burglar entrance to an unauthorized place. All the nodes are connected to a base station consisting of a launch pad and GSM module via wireless mesh network. Each of the nodes are internally connected via mesh network with the adjacent nodes as a backup protection during any device’s malfunction. If the stated node fails to process radio signal to the base station due to channel break then it can send signals via the node beside it.  After detecting any breaking noise, the sensor sends a signal by radio frequency to the base station and the GSM module generates an automatic call to the respective number along with a SMS. The flashing light locates the site of the event and the discerning node sends notification to its connecting node about the occurred incidence. If a burglar tries to disrupt any node, the PIR sensor detects from a 10 meter distance and will generate the alarm before he can proceed. The system requires very low power and hence ensures long battery life.
