Abstract

An approach is provided for coordinating information request messages over an ad-hoc mesh network. A module receives at least one request to transmit one or more information request messages over an ad-hoc mesh network. The module determines context information associated with at least a portion of the ad-hoc mesh network, one or more nodes within the at least a portion of the ad-hoc mesh network, or a combination thereof. The module then determines to transmit the one or more information request messages over the ad-hoc mesh network based, at least in part, on the context information.

Claims

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

receive at least one request to transmit one or more information request messages over an ad-hoc mesh network;

define at least one data schema based, at least in part, on a type and format of information requested by the one or more information request messages;

determine context information associated with a community of nodes within the ad-hoc mesh network;

generate the one or more information request messages based, at least in part, on the at least one data schema, the one or more information request messages including one or more filters specifying one or more criteria for selecting from among one or more information items matching the at least one data schema; and

transmit the one or more information request messages over the ad-hoc mesh network based, at least in part, on the context information.

2. An apparatus of claim 1, wherein the apparatus is further caused to:

set a state of the community to change a visibility of the community, a community member, or a combination thereof,

wherein the context information includes information associated with the management of the community.

3. An apparatus of claim 1, wherein the apparatus is further caused to:

determine respective weights for one or more elements of the context information,

wherein the transmission of the one or more information request messages is based, at least in part, on whether the respective weights exceed a threshold value.

4. An apparatus of claim 1, wherein the apparatus is further caused to:

determine that a new node has joined the ad-hoc mesh network,

wherein the transmission of the one or more information request messages is based, at least in part, on the determination with respect to the new node.

5. An apparatus of claim 1, wherein the one or more information request messages are associated with one or more transmission parameters, and wherein the transmission of the one or more information request messages is based, at least in part, on the one or more transmission parameters.

6. An apparatus of claim 1, wherein the one or more information request messages are generated by one or more applications using, at least in part, a publish/subscribe mechanism over the ad-hoc mesh network.

7. An apparatus of claim 1, wherein the apparatus is further caused to:

concatenate at least a portion of the one or more information request messages into a common message,

wherein the transmission of the one or more information request messages comprises transmission of the common message.

8. An apparatus of claim 1, wherein the one or more information request messages include one or more information publication messages, one or more information subscription messages, or a combination thereof, wherein the apparatus is further caused to:

transmit at least one of the information publication messages with at least one of the information subscription messages; and

associate published information against subscriptions for the published information based, at least in part, on the at least one data schema.

9. An apparatus of claim 1, wherein the apparatus is further caused to:

transmit the one or more information request messages as either a broadcast message or a unicast message based, at least in part, on the context information.

10. An apparatus of claim 1, wherein the apparatus is a mobile phone further comprising:

user interface circuitry configured to facilitate user control of at least some functions of the mobile phone through use of a display and configured to respond to user input; and

receiving at least one request to transmit one or more information request messages over an ad-hoc mesh network;

defining, by at least one processor, at least one data schema based, at least in part, on a type and format of information requested by the one or more information request messages;

determining, by the at least one processor, context information associated with a community of nodes within the ad-hoc mesh network;

generating, by the at least one processor, the one or more information request messages based, at least in part, on the at least one data schema, the one or more information request messages including one or more filters specifying one or more criteria for selecting from among one or more information items matching the at least one data schema; and

transmitting the one or more information request messages over the ad-hoc mesh network based, at least in part, on the context information.

13. A method of claim 12, further comprising:

setting a state of the community to change a visibility of the community, a community member, or a combination thereof,

wherein the context information includes information associated with the management of the community.

14. A method of claim 12, further comprising:

determining respective weights for one or more elements of the context information,

wherein the transmission of the one or more information request messages is based, at least in part, on whether the respective weights exceed a threshold value.

15. A method of claim 12, further comprising:

determining that a new node has joined the ad-hoc mesh network,

wherein the transmission of the one or more information request messages is based, at least in part, on the determination with respect to the new node.

16. A method of claim 12, wherein the one or more information request messages are associated with one or more transmission parameters, and wherein the transmission of the one or more information request messages is based, at least in part, on the one or more transmission parameters.
