Embodiment Construction

[0040] The present invention will be described in further detail below with reference to accompanying drawing

[0041] refer to figure 2 , the present invention divides the timing structure of mobile Ad hoc network signal transmission into periodic superframes, and each superframe is divided into several time frames, and each time frame is composed of a time scale signal domain and several time slots , the specific division method of the time slot is determined by the specific MAC layer protocol adopted.

[0042] refer to image 3 , in order to strengthen the management function of the network and simplify the complexity of network management, the present invention adds a dedicated management control channel in each time frame, and the management control channel in the time frame structure is mainly used to transmit the network access of new nodes Request signaling, response signaling to network access requests, and signaling for transmitting network topology information, n...

Abstract

The method is implemented through mutual exchange and mutual control of timing reference between two neighboring nodes. For scheduling, several neighboring time frames composes super frame, and a time signal domain is added into each time frame. Each node in the time signal domain of a certain time frame periodically transmits time signal to indicate its timing reference. Meanwhile in each super frame , each node also needs to receive the time signal of other nodes from which the timing reference is extracted. Based on the timing references, the timing reference of local node is adjusted. Then the node sends the time signal based on the adjusted timing reference.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a mobile wireless self-organizing network, that is, a mobile Ad Hoc network, specifically a method for mutual synchronization of a mobile Ad hoc network, which is suitable for wireless communications required by field communications, emergency search and rescue, temporary meetings, etc. The local area communication system is also suitable for the wired local area network of bus type and mesh type distributed control. Background technique [0002] Mobile Ad hoc consists of a group of autonomous nodes with equal characteristics, and has the characteristics of network system autonomy. Compared with the traditional wireless network, its remarkable feature is that it does not need to establish a fixed communication infrastructure, and only network nodes can form a complete network. In this network, all nodes are mobile, and each mobile node is both a terminal and a router, which ...
