摘要：Localization in Wireless Sensor Networks (WSNs) is very important. It can be used in various applications one of these applications is the Fire Rescue system. Localization means the determination of geographical locations of sensor nodes, consequently detecting the event location and to initiate a prompt action whenever necessary. The localization process passes with three phases which are distance and/or angle estimation phase, position phase, and algorithm phase. There are many techniques can be used in each phase, some of these techniques that may add additional devices, cost, power consumption, or delay to the network. This paper studied the most popular localization algorithms for WSN in each phase then demonstrated their problems with some suggestions for their solutions. Finally, the suitable Localization techniques for different categories of fire rescue system application will be recommended.
