Synchronization and data transmission method

Procedure for synchronization and communication in a network multihop ( "multihop") with multiple nodes (KN) and a central node (ZKN), each having at least one unit of transmission and reception, a storage unit and a processing unit, in which communication between units transmission and reception is based on wireless data transmission in frames that are divided in defined intervals, the kNs and ZKN are positioned together in space so in the area of ​​transmission and reception of each KN is at least another KN as its neighbor and / or ZKN, communication between the KN and ZKN is performed using other kNs as intermediate nodes via a communication jumping multiple, provided the KN is outside the broadcast area reception ZKN, and each KN is assigned at least a value of hop count indicating the number, increased by one, intermediate nodes for KN in question, through which communication with ZKN is performed, and wherein the intermediate node that is located closer to the corresponding KN in the network during communication with ZKN is called predecessor KN, KN is called successor the intermediate node and all kNs with the same counter value jumps form a layer, said method comprising the following steps: a) Issuance of a synchronization signal by the ZKN or for KN and synchronized, being occupied the so-called interval beacon interval is determined by the node that emits the synchronization signal in the frame of said signal with a data packet facilitates the synchronization, the so-called beacon and being transmitted at least the value of the hop count of the node which it emits, in the frame synchronization signal, and for all neighboring nodes already synchronized node issuing it knows, transmission intervals beacon occupied by the neighboring nodes and values ​​hop counter of neighboring nodes in the frame of the synchronization signal or as data signal separated by the node that emits, b) receiving the synchronization signal and the data transmitted in connection therewith by a first node that is located in the emission zone reception node emitted, c) synchronizing the first node with the synchronization signal, d) detecting the neighboring nodes of the first node, and the occupation of their respective beacon intervals and counter values ​​jumps the first node, e) determination of the predecessor of the first KN in the network by the first KN based on predefined criteria, f) storing the data received or detected by the first node by the synchronization signal, and in connection therewith and g) repeating steps a) to f), at least until all kNs are synchronized.
