| Sumario: | Wireless sensor networks (WSN) may be composed by tens or hundreds of nodes. Nodes measure variables and send their values to a base station through a shared low data rate wireless communication channel. Communication protocols for WSNs have been developed in order to support a large number of nodes. However, if a great deal of data is transmitted through a low speed communication channel, data packet congestion may happen. Congestion may lead to high latencies or data loss. Data congestion could take place in WSNs with a large number of nodes sending data periodically, or in WSNs where the data rate can increase when a specific event is detected. In this paper we analyze the conditions that lead to congestion of the communication channel considering the following nodes configuration parameters: (1) transmission time intervals, (2) data packet generation rate, and (3) transmitter output power level. © 2017 Elsevier Ltd. |
