Abstract

The invention relates to the technical field of wireless sensor networks, and in particular relates to a method for acquiring and allocating the GTS (guaranteed time slot) of an assured service as well as a wireless sensor network. According to the method and the wireless sensor network, a CFP (contention free period) length is divided into a plurality of equal-length time slots with small granularities, and the time slot lengths of sensor nodes are acquired according to an equal-length time slot with small granularity, and the defect of GTS waste is solved effectively; the restriction that only 7 devices in a superframe can apply for the GTS is broken through; moreover, a GACK (group acknowledge frame) is introduced so as to confirm sensor nodes integrally; the defect that an ACK (acknowledge frame) is sent frequently by a network coordinator so as to lead to excessive frame head part expense is prevented; and the wireless sensor node network bandwidth utilization ratio is improved greatly.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, in particular to methods for acquiring and allocating guaranteed time slots (Guaranteed Time Slot, GTS for short) for guaranteed services and wireless sensor networks. Background technique [0002] The wireless sensor node network is composed of a large number of miniature sensor nodes deployed in the monitoring area. It is a multi-hop self-organizing network formed by wireless communication. At present, the wireless sensor node network has been widely used, but the sensor node bandwidth and energy resources If the bandwidth is limited, energy will be wasted if the bandwidth is idle. Therefore, improving the bandwidth utilization of sensor nodes is an important technology for wireless sensor node networks. [0003] At present, the MAC (Medium Access Control) layer of the wireless sensor node network adopts the IEEE802.15.4 MAC layer protocol, and works in a non-beacon-ena...
