Abstract

The invention provides a QoS perception routing protocol method. The method comprises the steps of constructing a heterogeneous wireless sensor network model; generating an information structure according to the heterogeneous wireless sensor network model, and realizing information exchange through the information structure; by broadcasting the generated information structure, carrying out routingpath exploration on the wireless network to obtain an optimal routing path. Compared with the prior art, the QoS perception routing protocol method provided by the invention has the advantages that automatic disperse of a data load is realized; the transmission efficiency is improved; and the network utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of wireless network transmission, in particular to a method for a QoS-aware routing protocol. Background technique [0002] Adaptive routing protocols are ideal for HWSNs due to their own characteristics and key constraints. In multimedia sensor networks, protocols should provide QoS support and energy efficiency support. Although QoS in multimedia sensor networks has been considered in existing research, most studies consider homogeneous network nodes rather than heterogeneous network nodes. [0003] In WMSNs environment with heterogeneous nodes, there are less researches on applying swarm intelligence techniques to QoS provisioning. Some articles on WMSNs discuss the use of ant colony algorithm to provide QoS support in WMSNs and provide service differentiation by considering pheromone concentration separately for each service type. It results in the generation and maintenance of large pheromone tables. ...
