Routing is one of the most important technologies in wireless sensor networks. The energy efficiency of the sensor network is realized by combining other technologies with routing protocols in this paper. First, through the analysis of the energy model of the clustering routing algorithm, the local signal to noise ratio (SNR) is used to purposefully select the nodes in the cluster to transmit data. In order to avoid the energy consumption of a large number of nodes to transmit data, a simple architecture is proposed to combine the distributed source code with the cluster routing protocol. The method uses the data on the cluster head as the edge information to decode the compressed information transmitted from the cluster nodes. The simulation result shows that the energy efficiency of the network can be achieved through this combination.
Abstract. As one of the basic technologies for building Internet of Things, wireless sensor networks (WSNs) are a hot research topic at present. In this paper, two basic structures of WSNs are described briefly, and the current security situation and security risks of WSNs are introduced. Then, this paper summarizes several mainstream ways of attacking identity authentication schemes that are applied to WSNs, including smart card theft, wireless sensor node capture, vampire attack and collusion attack, and presents some defensive measures. Finally, attacking principles of these attack methods are summarized, and some improvements are put forward.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
