Apparatus and methods implement aggregation frames and allocation frames. The aggregation frames include a plurality of MSDUs or fragments thereof aggregated or otherwise combined together. An aggregation frame makes more efficient use of the wireless communication resources. The allocation frame defines a plurality of time intervals. The allocation frame specifies a pair of stations that are permitted to communicate with each other during each time interval as well as the antenna configuration to be used for the communication. This permits stations to know ahead of time when they are to communicate, with which other stations and the antenna configuration that should be used. A buffered traffic field can also be added to the frames to specify how much data remains to be transmitted following the current frame. This enables network traffic to be scheduled more effectively.

Resources to a device are granted access to an application based on privileges associated with the application. A permission list may be created by a server. The permission list may be created using information from authorities, entities, or parties and information about the device resources. The permission list indicates what device resources the application may access. During application execution when the application requests a resource, a control program executing on the device may be used to check the permission list associated with the application to determine if the application may access the resource. The control program can then grant or deny access based on the privileges defined in the permission list. Digital signatures may be used to detect modifications to the application and/or permission list. In addition, multiple permission lists may be associated with the same application.
