The present invention discloses a method and system for dynamically adjusting the routing interaction period of the star cluster ad hoc network, wherein the method includes the following steps: Step 1: After the designated node is turned on, the routing interaction period is initialized as T original , and with T original Periodically broadcast routing packets; Step 2: The designated node receives routing packets from other nodes to establish a local routing table that contains information on all nodes in the network; Step 3: The designated node periodically checks the local routing table, if the routing table entry is in a sufficiently long time If there is no increase or decrease, adjust the routing interaction period to T steady , and broadcast routing packets according to the adjusted cycle; if a change in the routing entry is detected, the routing interaction cycle is adjusted to T original , and broadcast routing packets according to the adjusted period. The invention solves the problem of relatively high link transmission overhead of the traditional table-driven routing protocol, and at the same time satisfies the requirements of fast convergence and simple and practical routing of the slowly dynamic changing star cluster ad hoc network.
Description
technical field [0001] The invention belongs to the field of satellite communication, and in particular relates to a method and a system for dynamically adjusting the routing interaction period of an ad hoc constellation network, which is suitable for ad hoc constellation networks with slow dynamic changes. Background technique [0002] The constellation network can maximize the satellite service capability, expand the satellite service scope, and effectively make up for various deficiencies in single-satellite in-orbit operation, so as to build a space service system with complete functions and stable performance. Due to the uncertain topology of the star cluster network and multi-hop transmission between satellites, it is necessary to solve the routing problem between multi-hop satellites to achieve efficient and reliable communication in the star cluster network. [0003] The performance of routing protocols is closely related to network topology, business types, and tran...
