Abstract
Protocols for ad-hoc wireless networks (200) that use mediation devices (202–210) to facilitate communication between low power, low duty cycle wireless devices (212–226) are provided. In order to avoid premature battery exhaustion in particular devices, devices operating as mediation devices (202–210) report their communication load to low duty cycle wireless devices (212–226) that are positioned to be able to use the mediation devices (202–210). Based on the information as to communication load received from multiple mediation devices (202–210), and optionally on a virtual hop count that is a predictor of how rapidly the use of a route through a particular mediation device will lead to battery exhaustion, low duty cycle wireless devices (212–226) choose a mediation device (202–210) to use or proportion use of mediation devices (202–210) in order to delay battery exhaustion in the network.
