Although originally the wireless sensor networks (WSN) were designed for transmitting environmental parameters with a low data rate, there is a growing need to use these networks for applications that require high throughput, such as real time localization systems (RTLS).However, the higher the amount of information to be transmitted through these resource-constrained networks, the more the number of communication problems (collisions, excessive delay and lack of coordination) can occur. This article presents a self-organized strategy, where the nodes exploit their own experience in previous transmissions to decide when to transmit future packets.The proposed strategy is evaluated within the protocol HCP (Highly Configurable Protocol), which was designed for indoor localization systems. Through simulations, we demonstrated that our proposal improves the performance compared with the method used originally by HCP.
