In post-disaster scenarios, such as after floods, earthquakes, and in war zones, the cellular communication infrastructure may be destroyed or seriously disrupted. In such emergency scenarios, it becomes very important for first aid responders to communicate with other rescue teams in order to provide feedback to both the central office and the disaster survivors. To address this issue, rapidly deployable systems are required to re-establish connectivity and assist users and first responders in the region of incident. In this work, we describe the design, implementation, and evaluation of a rapidly deployable system for first response applications in post-disaster situations, named RDSP. The proposed system helps early rescue responders and victims by sharing their location information to remotely located servers by utilizing a novel routing scheme. This novel routing scheme consists of the Dynamic ID Assignment (DIA) algorithm and the Minimum Maximum Neighbor (MMN) algorithm. The DIA algorithm is used by relay devices to dynamically select their IDs on the basis of all the available IDs of networks. Whereas, the MMN algorithm is used by the client and relay devices to dynamically select their next neighbor relays for the transmission of messages. The RDSP contains three devices; the client device sends the victim's location information to the server, the relay device relays information between client and server device, the server device receives messages from the client device to alert the rescue team. We deployed and evaluated our system in the outdoor environment of the university campus. The experimental results show that the RDSP system reduces the message delivery delay and improves the message delivery ratio with lower communication overhead.

This paper presents a networked robotic system design capable of enhancing wireless communication capabilities (communication range and bandwidth). The core of the system is active antenna tracking with directional antennas. The proposed system is decentralized and consists mainly of a mobile robot system and a command center system. Each system is equipped with off-the-shelf network devices such as antennas, access points (AP), and network switches. For directional antennas to be beneficial to our system, we propose a weighted centroid algorithm (WCA) to provide active antenna tracking and direction-of-arrival (DOA) estimation. This system can be used in GPS-denied environments as our system does not require the aid of additional sensors to provide location information. Through extensive field experiments in different environments, including a fire training center and with various antenna selections, such as omni-to-omni, omni-to-directional, and directional-to-directional antennas, we demonstrate the effectiveness of our proposed system. We expect that our system can be applied in a variety of rescue, surveillance, and emergency scenarios where high bandwidth and long-distance communications are needed.

Abstract-Researchers have been working on odour tracking and sniffing robotics research, the purpose of the research is to replace sniffer dogs in Odour Source Localisation (OSL) task. Sniffer dogs have constraints in performing OSL task i.e. indentify the location of suspicious items such as explosives, illegal drugs or poison gas, it is actually risking the sniffer dogs' life. Thus far, odour tracking robotics research has shifted from single sniffer robot to multi-sniffer robots. It is because multi-sniffer robots can perform OSL task cooperatively over wireless network communication. Most of the multi-sniffer robots use star network topology which has a limitation of short exploration distance. It is constrained by the transmission distance range of a server transmitter i.e. a server transmitter with star network topology has a transmission distance limit; its clients (multi-sniffer robots) can only search within the transmission distance limit. This paper proposes a network topology that extends the exploration distance of multi-robots especially for multi-sniffer robots application. The proposed method has successfully extended the exploration distance by multiplying the transmission distance range with the total number of multi-sniffer robots.Index Terms-Multiple robot systems, sniffer robots, odour source localisation, wireless network topology.
