Reliable method for managing wireless sensor network

Abstract

The invention discloses a reliable method for managing a wireless sensor network, which is used for managing and maintaining various wireless equipment in the wireless sensor network. The method comprises the following contents, wherein the type of the wireless equipment is classified into a wireless coordinator, a wireless router, a wireless terminal and a wireless mobile terminal; the wireless coordinator manages the access of other type wireless equipment to the network; the access mode of the wireless equipment comprises first network access and network re-access; through the dynamic maintenance of a network topology structure, the network access/withdrawal status of the wireless equipment in the network is reflected in real time; the frequency hops self-adaptively according to a wireless environment; and when the wireless environment is lower than a tolerance threshold, the frequency hops to a channel with the better wireless environment for communication. With the establishment of the reliable method for managing the wireless sensor network, the wireless sensor network service with higher quality and higher efficiency is provided to users.
