Method for collecting location information of mobile phone ad hoc network for emergency search and rescue

Abstract

The invention provides a cellphone ad-Hoc network location information collecting method for emergency rescue. By taking the advantages of non-mobility and low energy consumption of cellphones of people to be rescued and combining hierarchical network routing and left power of the cellphones, location information of the cellphones of the rescued people is collected into ad-Hoc network cellphones by the aid of the ad-Hoc network. Message formats are simplified, and times of message transmission of the cellphones in the network is controlled, so that average routing hops and total whole-network message transmission energy consumption are low, message transmission load of low-power cellphones is alleviated, and arrival success rate of messages is increased. Compared with a conventional routing algorithm, the cellphone ad-Hoc network location information collecting method has the advantages that routing maintenance energy consumption and average hops are remarkably improved; destination addresses are selected according to the routing hops and partition priority of power, energy consumption load during message transfer of the low-power cellphones is decreased, and message collection success rate is increased.

Description

technical field [0001] The invention relates to a mobile phone ad hoc network location information collection method for emergency search and rescue. Background technique [0002] In some harsh environments of emergency rescue, due to the location where there was no mobile phone signal or the communication base station has been damaged, traditional mobile phone calls, text messages, GPRS, etc. have become invalid, and the search and rescue personnel and the searched and rescued people buried under the rubble cannot be Effective exchange of information. [0003] Traditional emergency search and rescue communication solutions often use mobile hotspots, Bluetooth, wireless sensor networks and other technologies to achieve short-distance communication, but they all have shortcomings: [0004] Hotspot: In practical applications, the network based on hotspot can only achieve a single-hop connection, which has the disadvantages of small search and rescue range and low efficiency. ...

AI Technical Summary

Problems solved by technology

[0004] Hotspots: In practical applications, hotspot-based networks can only achieve a single-hop connection, which has disadvantages such as small search and rescue range and low efficiency

[0005] Bluetooth: In practical applications, Bluetooth has a short transmission range and can only achieve a single-hop connection

In addition, the security mechanism of the Bluetooth standard requires manual confirmation by the user during the transmission process, and transparent information exchange cannot be achieved.

[0006] Internet of Things wireless sensing technology: In practical applications, there are problems that cannot be ignored in emergency rescue based on wireless sensors. For example, the collection of signs requires survivors to carry medical sensors in advance and assume that they are already in use, but this is usually not realistic; using sensors Survivor positioning on the network requires the deployment of multiple anchor nodes. In large-scale disaster scenarios, large-scale networking is required, which not only takes a long time, but also costs a lot; using wireless sensor networks to build emergency communication facilities requires multi-hop data Transmission, at the current technical level, its stability cannot meet the high reliability needs of emergency rescue communications
