Abstract

A local device is configured to monitor operating conditions coupled to a wireless network. An advertisement period is dynamically adjusted based on the operating conditions of the local device, where the advertisement period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be advertised. The local device broadcasts a service advertisement in the wireless network according to the adjusted advertisement period, the service advertisement including one or more service IDs for identifying one or more services to be advertised from the local device.

Claims

1. A machine-implemented method for advertising a service in a peer-to-peer networking environment, the method comprising:

monitoring operating conditions of a local device coupled to a wireless network;

dynamically adjusting an advertisement period based on the operating conditions of the local device; and

broadcasting, by the local device, a service advertisement in the wireless network according to the adjusted advertisement period, the service advertisement including one or more service IDs for identifying one or more services to be advertised from the local device.

2. The method of claim 1, wherein the advertisement transmission period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be advertised.

3. The method of claim 1, further comprising:

dynamically adjusting a discovery period based on the operating conditions of the local device; and

listening, by the local device, in the wireless network according to the adjusted discovery period in an attempt to receive a service advertisement from a remote device over the wireless network.

4. The method of claim 3, wherein the discovery period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be discovered.

5. The method of claim 3, wherein the advertisement period is calculated as a product of a predetermined base value and a first adjustment factor, and wherein the advertisement period is dynamically adjusted by adjusting the first adjustment factor.

6. The method of claim 5, wherein the discovery period is calculated as a product of the predetermined base value and a second adjustment factor that is different than the first adjustment factor, and wherein the discovery period is dynamically adjusted by adjusting the second adjustment factor.

7. A machine-readable storage medium having instructions stored therein, which when executed by a machine, cause the machine to perform a method for advertising a service in a peer-to-peer networking environment, the method comprising:

monitoring operating conditions of a local device coupled to a wireless network;

dynamically adjusting an advertisement period based on the operating conditions of the local device; and

broadcasting, by the local device, a service advertisement in the wireless network according to the adjusted advertisement period, the service advertisement including one or more service IDs for identifying one or more services to be advertised from the local device.

8. The machine-readable storage medium of claim 7, wherein the advertisement period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be advertised.

9. The machine-readable storage medium of claim 7, wherein the method further comprises:

dynamically adjusting a discovery period based on the operating conditions of the local device; and

listening, by the local device, in the wireless network according to the adjusted discovery period in an attempt to receive a service advertisement from a remote device over the wireless network.

10. The machine-readable storage medium of claim 9, wherein the discovery period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be advertised.

11. The machine-readable storage medium of claim 9, wherein the advertisement period is calculated as a product of a predetermined base value and a first adjustment factor, and wherein the advertisement period is dynamically adjusted by adjusting the first adjustment factor.

12. The machine-readable storage medium of claim 11, wherein the discovery period is calculated as a product of the predetermined base value and a second adjustment factor that is different than the first adjustment factor, and wherein the discovery period is dynamically adjusted by adjusting the adjustment factor.

13. A portable device, comprising:

a wireless transceiver;

a monitor coupled to the wireless transceiver to monitor operating conditions of the portable device coupled to a wireless network; and

a service advertisement unit coupled to the monitor and the wireless transceiver to dynamically adjust an advertisement period based on the operating conditions of the portable device, wherein the service advertisement unit is configured to broadcast according to the adjusted advertisement period, via the wireless transceiver, a service advertisement in the wireless network, the service advertisement including one or more service identifiers (IDs) identifying one or more services to be advertised.

14. The portable device of claim 13, further comprising a service discovery unit coupled to the monitor and the wireless transceiver to

dynamically adjust a discovery period based on the operating conditions of the local device, and

listen in the wireless network via the wireless transceiver, according to the adjusted discovery period in an attempt to receive a service advertisement from a remote device over the wireless network.

15. The portable device of claim 14, wherein at least one of the advertisement period and the discovery period is dynamically adjusted based on at least one of a battery condition of the local device, a user behavior of the local device, network traffic condition, and a type of service to be advertised or discovered.

16. The portable device of claim 14, wherein the advertisement period is calculated as a product of a predetermined base value and a first adjustment factor, and wherein the advertisement period is dynamically adjusted by adjusting the first adjustment factor.

17. The portable device of claim 16, wherein the discovery period is calculated as a product of the predetermined base value and a second adjustment factor that is different than the first adjustment factor, and wherein the discovery period is dynamically adjusted by adjusting the second adjustment factor.

18. A machine-implemented method for discovering a service in a peer-to-peer networking environment, the method comprising:

determining operating conditions of a local device coupled to a wireless network;

dynamically adjusting a discovery period based on the operating conditions of the local device; and

listening, by the local device, in the wireless network according to the adjusted discovery period in an attempt to discover a service advertised by a remote device over the wireless network.

19. The method of claim 18, further comprising:

dynamically adjusting an advertisement period based on the operating conditions of the local device; and

broadcasting, by the local device, a service advertisement in the wireless network according to the adjusted advertisement period, the service advertisement including one or more service identifiers (IDs) identifying one or more services to be advertised from the local device.

20. A machine-readable storage medium having instructions stored therein, which when executed by a machine, cause the machine to perform a method for advertising a service in a peer-to-peer networking environment, the method comprising:

determining operating conditions of a local device coupled to a wireless network;

dynamically adjusting a discovery period based on the operating conditions of the local device; and

listening, by the local device, in the wireless network according to the adjusted discovery period in an attempt to discover a service advertised by a remote device over the wireless network.

21. The machine-readable storage medium of claim 20, wherein the method further comprises:
