Abstract

Embodiments of the invention disclose a method and equipment for exception handling of relays in a wireless sensor network. The method comprises the following steps of obtaining an uplink bandwidth of a second relay and an uplink bandwidth of a third relay when state exception of a first relay is detected; determining first partial cache data and second partial cache data in cache data of the first relay according to the uplink bandwidth of the second relay and the uplink bandwidth of the third relay; sending a cache data migration command to the first relay; and receiving the first partial cache data sent by the second relay and the second partial cache data sent by the third relay. The embodiments of the invention are helpful for improving the integrity and the real-time performance of data transmission when the relays in the wireless sensor network have exceptions.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and equipment for abnormal processing of a wireless sensor network repeater. Background technique [0002] The wireless sensor network in the application of the Internet of Things is composed of the Internet of Things gateway, the Internet of Things wireless access point, the Internet of Things terminal and the repeater (the Internet of Things terminal with partial power supply and built-in routing algorithm can act as a repeater), Data collection via IoT terminals, data transmission via IoT wireless access points and IoT gateways. The Internet of Things has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; Information exchange and communication, that is, things are closely related. The Internet of Things is widely used in the integration of networks through communi...
