摘要： The present invention provides a method, test-bed and computer program product for testing an application installed on a wireless communication device. The wireless communication device communicates one or more messages wirelessly to a server through a test-bed. The test-bed is connected with the server and provides one or more testing parameters for the one or more messages. A tester, testing the application, assigns a probability to the one or more messages. Further, the tester assigns a probability to the one or more testing parameters. Thereafter, the messages are re-communicated between the server and wireless communication device through the test-bed. Subsequently, the one or more messages are identified by the test-bed and one or more wireless network conditions are emulated based on the probabilities assigned to the one or more messages and the one or more testing parameters.

摘要： A system and method for robust data loss recovery in a wireless local area network is provided. The method includes splitting user data into multiple data fragments. The method further includes creating multiple beacon frames by placing each data fragment in a unique beacon frame and broadcasting the beacon frames through a wireless medium by an access point of the network. Prior to transmission, the method includes arranging the frames into a plurality of groups and creating a parity frame for each group, to be transmitted along with the beacon frame. After transmission, the beacon frames are received by a wireless client and data fragments are extracted from each beacon frame. At the receiving end, the wireless client checks whether all the transmitted beacon frames have been received. Finally, the user data is reconstructed from the extracted data fragments by reassembling the data fragments.
