Abstract
Methods, apparatuses, and systems directed to managing wireless node access to one or more wireless networks. According to one implementation, a business logic application may function as a package tracking application to manage access to wireless access points in different WLANs along the route. A sensor node is initialized and configured with one or more connection parameter sets allowing it to associate with a given wireless network implemented by one or more access points. In one implementation, the sensor node is configured only to accept received wireless frames that it can properly decrypt using the currently stored encryption key. When the sensor node and such a wireless access point associate, they may exchange encrypted information (e.g., data regarding the package) using an encryption key. Before the sensor node disassociates with time wireless access point, the wireless access point transmits a new connection parameter set to the sensor node.
