A Robust Emergency communication in hills and forest using LORA Communication
ABSTARCT :
The need for efficient fire detection systems is highlighted by the substantial threats that forest fires pose to both human lives and the ecosystem. Limited coverage, high false alarm rates, and delays in signal transmission are just a few of the problems traditional methods for detecting forest fires sometimes encounter.
This research study suggests a unique strategy that uses long-range (LoRa) communication technology for forest fire detection to address these problems. LoRa allows for long-range, low-power wireless communication, making it appropriate for installation in sparsely populated, off-the-grid forest areas.
This study investigates the development, application, and assessment of a LoRa-based forest fire detection system. The suggested system includes a network of sensor nodes outfitted with LoRa transceivers and fire detection sensors. The sensor nodes send real-time data to a centralised control centre while continuously monitoring environmental variables like temperature, humidity, and smoke.
Complex algorithms are used by the control centre to analyse the data it receives and identify probable fire issues. When a fire is discovered, the system immediately creates notifications and sends them to the appropriate authorities and local communities.
Numerous field tests were carried out in various forest settings to gauge the success of the suggested strategy. The outcomes show the system's capacity for precise fire detection, minimal false alarm rates, and quick response times. A viable option for early forest fire detection and prevention, the LoRa-based system also shown its benefits in terms of broad coverage, long-range communication, and energy economy.
This study advances forest fire management systems by laying the groundwork for the creation of reliable, scalable, and affordable fire detection technologies that can lessen the devastation caused by forest fires. This research paper's main goal is to offer a thorough analysis of the development, use, and evaluation of a LoRa-based forest fire detection system.
EXISTING SYSTEM :
LOss Differentiation Rate Adaptation scheme in this paper. LORA can estimate the average packet loss rate for each sender and differentiate the fading losses from the interference losses.
DISADVANTAGE :
communication networks are very important during a disaster, because rescue and recovery largely depend on the communication channel provided.
However, once a disaster occurs, the traditional communication network is fragile; at this time, a temporary communication system, namely an emergency communication network, should be built as soon as possible.
PROPOSED SYSTEM :
A cooperative scheme for medium access control (MAC) in VANETs, referred to as Cooperative ADHOC MAC (CAH-MAC) is proposed.
In CAH-MAC, neighboring nodes cooperate by utilizing unreserved time slots, for retransmission of a packet which failed to reach the target receiver due to a poor channel condition.
ADVANTAGE :
An emergency communication system comprises the integration and application of various communication technologies and approaches in an emergency.
Therefore, the emergency communication system should make full use of mature communication technologies and network equipment, and integrate them into an extensible and reliable secure communication network.
Generally, the emergency communication network uses the existing fixed wire network, the mobile cellular network , the Internet, and other public communication networks. Private communication networks, such as trunking communication networks satellite communication networks , and short-wave communication networks , will also be used. In addition, public media networks are also used, such as radio, television, and newspapers, as well as on-site monitoring and rescue networks, such as sensor networks and ad hoc networks .
