Methods, systems, computer-readable media, and apparatuses for providing anti-rollback protection in a device which has no internal non-volatile memory are presented. One embodiment is a device for providing anti-rollback protection. The device may obtain a firmware version number associated with a first firmware installation for the device, wherein the device is implemented on a substrate that includes no non-volatile memory. The device may obtain a lowest acceptable firmware version number, wherein the lowest acceptable firmware version number is stored in a secure element environment, wherein the secure element environment utilizes memory separated from the substrate. The device may compare the firmware version number and the lowest acceptable firmware version number, wherein if the firmware version number is less than the lowest acceptable firmware version number, then disallow the first firmware installation.

Mesh communications aspects are disclosed in which multiple mobile devices located within a communication area perform direct communication to establish a mesh network. Each device node included in the mesh network provides power profile information to the other nodes on the network. As mesh messages are generated for transmission by the nodes onto the mesh network, an adaptive routing mechanism determines the transmission route based on the power profile of the proposed target node. The selective and adaptive routing determination allows for power to be efficiently conserved within the mesh network.
