[0002] Wireless ad hoc network technology is a network that combines mobile communication and computer network. It has the characteristics of being centerless, self-organizing, and self-healing. It can be widely used in emergency communication, military communication and other fields. In the field of emergency communication, ad hoc network technology has gradually been widely used due to its unique advantages. Its centerless and flexible networking characteristics enable it to quickly establish a temporary communication network in the case of damage to the communication infrastructure, and realize key communication functions such as on-site command, rescue and relief, and material allocation. Ad hoc network technology can also be combined with other communication technologies to form a more powerful emergency communication solution, such as combining with cellular networks to build a hybrid wireless communication network to improve the stability and adaptability of communication. The widespread application of wireless ad hoc network technology solves the communication problems needed for emergency rescue of complex urban buildings such as railways, high-rise buildings, underground buildings, and large complexes, as well as major natural disasters such as earthquakes, floods, and mudslides.
