Abstract: An approach is provided for collaboratively synchronizing devices in an ad hoc network. No device is acting as a master device or base station dictating time slot allocation to devices. A first device communicates with the other devices by a Media Access Control scheme based on time frames having time slots. Responsive to a determination that a current time slot allocated to a second device is occurring, a determination that a Boolean value selected according to a predetermined probability is true, and a transmission of a map of allocations of time slots to the devices, the first device determines the map indicates a conflict in which the same time slot is allocated to the first device and another device. The first device resolves the conflict by allocating another time slot to the first device, so that each time slot is allocated to no more than one corresponding device.

In response to the action being identified, one or more word objects are extracted from the message. A first combination of one or more concepts is derived. from the one or more word objects. Each concept of the one or more concepts is associated with at least one object of the one or more word objects. Each word object is an instance of the associated concept. A first interest value associated with the first combination is determined. In response to a determination that the first interest value is at least a specified first threshold value, a concept interest dataset that includes combinations of concepts is updated. The updated concept interest dataset includes the first combination and a cumulative interest value that encompasses the first interest value.

Abstract: A masterless time slot allocation technique that collaboratively synchronizes, at a time slot level, devices communicating in an ad hoc network. Responsive to determining a current time slot allocated to a first device is occurring, the first device transmits a map to the other devices. The map includes an allocation of time slots to the devices, including indicators for whether each time slot is free, busy or overbooked, devices that own the time slots, and how recently information associated with each time slot was updated. After receiving the map, a second device determines a conflict in which the same time slot is allocated to the second device and to another device. The conflict is resolved by allocating another time slot to the second device and the result of resolving the conflict is each slot is allocated to no more than one device.

Abstract: A method, computer program product and system of handling usage of software in a disconnected computing environment. A digital certificate including time frame constraints is generated, signed by a certificate authority and associated to the software. To be executed, the digital certificate previously signed must be validated by the certificate authority by checking public keys and the time frame constraints must be simultaneously satisfied in the disconnected computing environment. The use of software is controlled in disconnected computing environments and/or read-only computing environments, i.e. environments which are not modifiable or in which brought modifications are not persistent. The data collected by the software may be further encrypted and thus be controlled.
