Objective: This research aims to enhance search and rescue operations through the development of a Sensor-based Rescue Management System (SRMS). The objectives include proposing architectures for pre and postdisaster scenarios, designing prototypes for a Smart Band and Hand Held Device (HHD), and conducting experimentation, results analysis, and power consumption analysis. Methodology: The SRMS architecture enables timely assistance to end users and provides precise information to rescue teams. In pre-disaster scenarios, the smart band communicates the user’s health status to a centralized server via the infrastructure. Notifications are sent to rescue teams for prompt response. In post-disaster situations, where the network infrastructure is damaged, rescue teams use HHDs to log sensor data from smart bands. The HHDs store the information offline and transmit it to the server when network connectivity is restored. Local HHD applications analyze the data for abnormalities, while server applications analyze sensor data to direct additional rescue teams. Findings: The SRMS utilizes lowpower wireless mesh network technology with multi-hop communication. Field experiments demonstrated the system’s affordability, scalability, and ability to generate alerts in medical emergencies. Power analysis indicated that the smart band prototype has a battery life of approximately 6 days with a 300 mAh battery, while the HHD can run for approximately 9 hours with a 5000 mAh battery. Novelty: This proposed system offers quick deployment, scalability, cost-effectiveness, and optimization of end node lifespan. It introduces novel architecture design, end node and HHD prototypes, and the use of low-power wireless technologies in various terrains. Additionally, the SRMS addresses offline connectivity by storing sensor data and transmitting it when network connectivity is restored. It significantly improves decision-making quality, efficiency, and effectiveness in disaster management activities.
