32. Cluster-Based Two-Level Mesh Routing Protocol for Wireless Sensor Network

Wireless sensor networks (WSNs) have broad application scenarios in military and civilian fields. How to reduce the energy consumption of network communication and extend the life cycle of the network has always been a research focus of WSN. Clustering is one of the important methods to extend the network life cycle. However, the existing clustering routing protocol has room for further optimization of the connection mode between the common node and the cluster head node, the network topology structure and the communication mode between nodes. In this paper, a cluster-based two-level mesh (CTM) routing protocol for WSN is proposed, which supports common nodes to connect to the cluster head and communicate with any node in a multi-hop manner. It also specifies the topological structure of the two-level mesh and two communication modes. Finally, simulations on the OMNeT++ platform verify that the protocol can effectively reduce network and energy costs.
