摘要：Wireless Sensor networks (WSNs) are used to monitor and control the physical environment in different classes of applications.Due to the dense deployment of sensors and as the sensor observations are spatially correlated with respect to location of sensor nodes, it is not necessary for every sensor to transmit its data. Therefore,becausethe resource constraints of nodes, it is necessary to select the minimum number of nodes to transmit the data to the sink and hence minimize the energy consumption. In this paper we develop a new scheme using the energy-aware immune system and this method selects the minimum number of designated nodes that can send its data to the sink and significantly reduce the energy consumption. In addition, considering the remaining energy of the designated nodes, their energy is balanced. Simulation results have been conducted and verified the effectiveness and efficiency of our proposed.
