The development of Wireless Sensor Network (WSN) in recent years, researchers are in it. The topics studied by many researchers are energy consumption, coverage and connectivity in WSN. This paper will discuss WSN in the presence of a simple obstacle or resistor. The LEACH protocol algorithm is used and modified in which there is an obstacle or obstacle with multi sink. We propose an algorithm based on line intersections to improve the original LEACH algorithm with multi sink. The simulation results show the modified LEACH algorithm will work better than the original LEACH in the presence of multi-sink based on energy consumption and loss of transmission data. Future research will have arbitrary obstacle modifications.
