This paper presents a comparative study between physical topologies that support WSN in order to determine the most efficient applied to a wireless network of environmental sensors. The research was performed by the support of Network Simulator 2 (NS-2), it allows to create an environment similar to real and simulated its operation, to determine the best topology an inductive method was applied to evaluate the data from NS-2 that were based on the performance metrics such as: sending packages, energy consumption and coverage. As a result it was obtained that the star physical topology is the best to implement a WSN network for environmental measurements, that has Packet Delivery Ratio of 97,9 %, Throughput of 0,7542 Kbps, a delay of 0,0162 ms, a low energy consumption and a greater sensor coverage area.
