This paper aims at eliminating unnecessary sensing nodes to minimize energy consumption with information accuracy constraint by proposing an Information-accuracy-aware Jointly Sensing Nodes Selection algorithm (IJSNS). We give an information accuracy model which formulates the relationship between information accuracy and jointly sensing nodes. Based on this model, we propose an IJSNS which allows a WSN to energy-efficiently distribute its sensing tasks with the information accuracy constraint. Simulation results have demonstrated the efficiency of IJSNS on selecting a proper set of jointly sensing nodes in optimizing the information accuracy and energy consumption.
