Embodiments of the present invention include a multi-user, multi-device alarm system, which, according to some embodiments, maintains the confirmation status of the alarm creator and participants, any communications between the alarm creator and participants, and user management functionality. Embodiments include systems and methods for configuring and executing different types of alarms, including personal alarms, group alarms, buddy alarms, and team alarms. The same or alternative embodiments may include cascading notifications to participants of an alarm until the alarm creator or one of the participants marks the alarm as done.

Social alarms and reminders

Simulation models of media access control and physical layer characteristics facilitate the simulation/emulation of a variety of phenomena that affect transmissions via a wireless media. Such phenomena include media access contention delays, packet drops, and retransmissions that are generally dependent upon changes in transmitter/receiver locations. Each wireless environment is characterized by a model of the communication channel that characterizes transmission effects based on the number of competing transmitters in the environment, which is dynamically determined based on the location of each node in the environment. Additionally, the location of nodes is used to simulate the effects of 'hidden nodes', nodes that are unknown to a transmitting node but can interfere with the reception of transmissions at a receiving node. Each device/node model in the wireless environment preferably accesses the same model of the communication channel, thereby minimizing the amount of detail required at each device model.
