Problems solved by technology

[0004] However, in the Ad hoc communication network based on the AODV protocol, the mobility of nodes will also cause another problem, that is, the optimal routing path in the Ad hoc communication network will become a suboptimal routing path. In this case, the Ad hoc Although the communication network can transmit data through suboptimal routing paths, it increases the delay of data transmission and reduces the energy efficiency of nodes.

Abstract

The invention discloses an Ad hoc communication network optimization method comprising the steps of monitoring each node on a current routing path in an Ad hoc communication network in real time; if it monitors that a new neighbor node appears in neighbor nodes of any node on the current routing path, judging whether the new neighbor node meets a preset communication transmission requirement, if yes, implementing path optimization processing between the new neighbor node and the node on the current routing path, so as to screen out the optimal routing path with the shortest path distance from all available paths; and if the optimal routing path is different from the current routing path, switching a communication link between the start node and the target node to the optimal routing path from the current routing path. According to the method and system of the invention, data transmission delay in the Ad hoc communication network is reduced, and energy efficiency of the node is improved. In addition, the invention also correspondingly discloses an Ad hoc communication network optimization system.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to an Ad hoc communication network optimization method and system. Background technique [0002] Ad hoc communication network (Ad hoc, that is, point-to-point) is a wireless multi-hop network. There is no fixed infrastructure in this network, and each network node is mobile, and each node can act as a host and a router. [0003] The AODV protocol (AODV, Ad hoc On-demand Distance Vector Routing) is an on-demand routing protocol applied in Ad hoc communication networks. In the case of link interruption or link failure in the Ad hoc communication network due to node mobility, the AODV protocol can solve the above-mentioned link interruption or link failure problem by starting a local repair mechanism, and can better maintain the Ad hoc network. Link structure of active routes in a communication network. [0004] However, in the Ad hoc communication network based on the...
