Relay Communication Solutions for First Responders

Abstract

First Responders (FRs) frequently intervene in dangerous environments, result of natural catastrophes, technological disaster or terrorist attacks, for that it is crucial to maintain their protection and operational effectiveness, namely their capacity in terms of situational awareness and communication in adverse situations. In the event of a disaster, communication networks may not be available at all, different reasons e.g. infrastructure collapse, denial of service or even the area of the incident may not be covered by communication services. This paper presents innovate project to respond to emergencies, focus on a resilient network solution easy to be deployed, to mitigate this problem and extent the existent communication networks. The solution uses nodes to relay communications from the nearest point to a farthest point with live communications, permitting long range communication of FR’s wearable sensor data. The nodes can be installed in UAVs (Unmanned Aerial Vehicle), mounted on the ground on tripods or even on UGVs (Unmanned Ground Vehicle), the solution is modular and auto-configurable. The core/backbone of the Wireless Resilient communication network is supported in Mesh topology (802.11s), that provides any-to-any connections between nodes, these nodes can be dynamically added or removed, the network will always try to find a path to deliver data, each node is also simultaneously Wi-Fi Access Point (802.11n).
