Discrete Markov-Based Topology Control of Star-Wireless Sensor Network for Lifetime Maximization

Star-wireless sensor network is the basic structure of most large-area wireless sensor network applications and is very important in many wireless sensor network applications. Its lifetime directly affects the performance of the network. To maximize the network lifetime, this paper proposes a topology control algorithm based on discrete Markov for star-wireless sensor networks. Based on discrete Markov theory, the node is divided into two states. The lifetime of the node is predicted by the number of transfers, and the topology control is carried out while the lifetime of the node is predicted. The simulation results show that this algorithm can improve the network lifetime.
