Monitoring model of Wireless sensor networks based on state

Network model is the foundation of network performance optimization and network practical applications. Some basic network monitoring requirements were presented by analyzing the issues associated with existing models and node deployment of Wireless sensor networks (WSNs). Focusing on the network monitoring performance, a monitoring model of state based WSNs was proposed. The state information of single node was denoted as a vector in the model, including work state, position state, energy state, sensing and communication relations of nodes. A WSN could be denoted as a matrix which was composed of state vectors of nodes. Several examples were illustrated to demonstrate the applicability of the proposed model in some researches of WSNs, including energy control, topology reconfiguration, and performance evaluation. The model provides a platform to evaluate capabilities, functionalities, and behaviors of a WSN from the mathematics perspective.
