Wireless Personal Area Network and PSO-Based Home Security System

Abstract

For monitoring and controlling unwanted events like intrusion of burglars/thieves at home/locality/city, the security systems are much required. In this paper, an efficient and low-cost wireless security system is proposed with ZigBee and GSM modems. In the proposed system, city is divided into sections and sections into colonies/sectors. The section security system comprises multiple cluster nodes with one cluster head. Cluster nodes and cluster head are linked via ZigBee network. The cluster heads of all sections communicate with central control room (main server) of the city via GSM in order to make its coverage area large. The network optimization for efficient routing of the cluster node and cluster head is done using PSO algorithm. Cluster node is an embedded device connected with ZigBee modem and switches in each room as per user’s requirement. If there is an intrusion at home, in any locality of the city, the resident is to press the switch. This information is communicated by cluster node through ZigBee network to the corresponding cluster head which in turn communicates to the central control room (main server) via GSM network. Cluster head is equipped with audio alarm system like a hooter and this system is activated as soon as the switch in the cluster node is pressed. The identity of cluster node is conveyed to the cluster head via communication network. For future enhancement, the system in the cluster node may be fitted with other sensors like temperature, smoke, fire, etc., for detection of various hazardous conditions.
