The invention discloses a method for making a wireless sensor network connected doubly and optimizing communication paths, and mainly relates to the reliability of a wireless sensor network. If the wireless sensor network is not connected doubly after being deployed, node failure can make the network not connected, thereby reducing sensing and monitoring coverage and influencing the service life of the network. The method uses a breadth-first principle based search method to find biconnected components in the network, acquire breadth-first spanning tree, record biconnected component information and judge nodes, and then uses a greedy method to increase nodes as few as possible. The method reduces the length of part of communication paths from sensing nodes to aggregate nodes and relay energy consumption and prolongs the service life of the network while realizing double network connection and improving connection reliability.
Description
Method for Dual Connectivity and Optimizing Communication Paths in Wireless Sensor Networks technical field The invention relates to a computer network technology, in particular to a method for improving the reliability of a wireless sensor network. Background technique If the dual connectivity cannot be achieved after the wireless sensor network is deployed, the failure of the nodes in the network (due to equipment failure or node energy exhaustion) will cause the network to be disconnected, reduce the coverage of sensing and monitoring, and affect the life of the network. Users hope that the network can be reliably connected and used stably and reliably. In the prior art, there are some researches on the realization of network dual connectivity, but various problems still exist. For example, in the literature A.Kashyap, S.KhullerandM.Shayman.Relayplacementforhigherorderconnectivityinwirelesssensornetworks.IEEEInfocom'2006, Barcelona, Spain proposed a dual-connectivity...
