| Resumen |
Wireless sensor networks are used extensively to monitor different environments and physical variables. However, in many cases, there are many nodes in the same region and given its distributed nature, these networks can suffer from corrupted data if too many transmissions occur at once. Therefore, it is important to maximize the number of successful transmissions while also minimizing the amount of energy used to transmit this data. The main component of wireless sensor networks that impacts these variables is the transmission probability. Thus, it follows that to improve successful transmission probability and to reduce energy consumption, an adequate transmission probability value should be selected. In particular, we propose the use of a transmission probability that decrease as the energy consumption increases in such a way as to reduce energy consumption towards the end of the system lifetime but that still allow the reporting of the events, i.e., packet transmissions. To this end we propose and evaluate the system performance in terms of average energy consumption and successful packet transmission probability using different mathematical functions for the transmission probability that decrease as the energy consumption increases but do not decrease to zero, allowing sporadic transmissions towards the end of the system operation and compare them to the case of using a fix value. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG. |
