Wireless ad-hoc emergency communication network based on network cluster and message ferrying

Abstract

The invention discloses a wireless ad-hoc emergency communication network based on network cluster and message ferrying. The network comprises an emergency on-site command center (ECC), multiple emergency rescue special communication nodes (ECNs), a great quantity of ordinary communication nodes (OCNs) and a moderate number of ferrying nodes, wherein the ECC can be used as a command coordination node of the whole emergency communication network and a cluster node of the ECNs in the coverage area of the ECC; the ECNs can be used as cluster nodes of the OCNs in the coverage area of the ECNs; the cluster nodes and gateway nodes are interconnected to form wireless backbone networks (WBNs), the OCNs are connected with handy WBNs to which the OCN belong; and relay communication can be realized among the OCNs in different WBNs through the ferrying nodes. The communication network provided by the invention dynamically integrates the network cluster mechanism and the message ferrying mechanism, thus enhancing the reliability and timeliness of information delivery.

Description

technical field [0001] The invention relates to a wireless ad hoc emergency communication network service enhancement technology, in particular to a wireless emergency ad hoc communication network based on network clustering and information ferry delivery. Background technique [0002] When wars, large-scale natural disasters or public emergencies occur, existing communication network facilities are likely to be destroyed in areas where public emergencies occur. The impact and short-term surge of communication volume often cannot meet the special needs of emergency communication time burst, location uncertainty, business urgency and information diversity. Wireless Self-organizing Network (Wireless Self-organizing Network) is a special mobile communication network that has received extensive attention and research in recent years. Nodes in the network have both the functions of hosts and routers, and are self-organizing, self-healing, centerless, multi- It can quickly and au...
