Routing strategy updating method based on naming data network under MANET environment

Abstract

The invention discloses a routing strategy updating method based on a naming data network under the MANET environment. The method comprises the steps that when a mobile node detects that the mobile node is moved from a first node to a second node, whether the first node or the second node receives a position updating interest packet sent by the mobile node or not is judged, after the first node receives position updating information, if the first node and the second node are directly connected, FIB information is directly updated, if not, the information is forwarded to adjacent nodes, and corresponding item parameters of the FIB are set to be determined; if the second node receives the information, if the second node and the first node are directly connected, no action is performed, if not, the second node informs the adjacent nodes, if one adjacent node has matched items to be determined, FIB is updated, and if not, the adjacent nodes continue to broadcast and seek. According to thetechnical scheme, the interest packet response rate is increased, the data packet obtaining delay is lowered, the phenomenon of service interrupt caused when the node moves is effectively lowered, andthe network performance is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a routing strategy update method based on named data network under MANET environment. Background technique [0002] In the prior art, MANET is the abbreviation of Mobile Ad hoc network, and the Ad hoc network is a kind of self-organizing network, which is divided into fixed nodes and mobile nodes. MANET specifically refers to an Ad hoc network in which nodes have mobility. MANET is a new multi-hop, temporary and self-organizing network composed of wireless mobile nodes. Unlike traditional wireless networks, MANET does not need to rely on fixed communication network infrastructure and can be used quickly, and users do not need to pay for data sharing. Nodes in the network can enter and leave the network dynamically, freely and frequently without disrupting the communication of other nodes in the network. They not only process data as terminals, but also forward da...

This method causes unnecessary detours, undoubtedly increases unnecessary network traffic, and increases the round-trip delay of request responses. In addition, when a large number of nodes access the home entity at the same time, it may also cause network congestion.
