EXPERIMENTAL CHARACTERIZATION OF COMMUNICATION LATENCIES IN WIRELESS SENSOR NETWORK
Abstract
The communication latency between Wireless Sensor Network (WSN) nodes can significantly affect the performance of real-time monitoring applications, especially when multi-hop network topologies are used. In fact, the end-to-end network delays may hinder the collaboration between different devices, thus preventing the applicability of data fusion algorithms or limiting the accuracy of internode time synchronization. Unfortunately, performing a thorough characterization of such latencies is not an easy task because they may depend considerably on the overall network data traffic as well as on the typical vagaries of RF links. In order to have a deeper insight about the communication latencies in nowadays WSNs, in this paper a suitable measurement procedure is described and some experimental results for different packet sizes, traffic conditions and number of hops are reported.
