20100302945 | METHOD AND APPARATUS FOR PROVIDING A COLLABORATIVE REPLY OVER AN AD-HOC MESH NETWORK - An approach is provided for providing a collaborative reply to a flooding message over an ad-hoc mesh network. A reply message to a flooding message is received by a wireless node within the ad-hoc network. The wireless node monitors for an acknowledgement of receipt of the reply message according to a routing table and initiates a scheduled transmission of the reply message based on the monitoring. | 12-02-2010 |
20100302947 | METHOD AND APPARATUS FOR PROVIDING AWARENESS INFORMATION OVER AN AD-HOC MESH NETWORK - An approach is provided for providing awareness information over an ad-hoc mesh network. Flooding messages (e.g., containing either queries for or awareness information) are transmitted between neighboring nodes of an ad-hoc mesh network. The nodes then retransmit the flooding messages within the ad-hoc mesh network based on predetermined criteria. Reply messages containing requested awareness information are generated to the queries and routed back to the querying node over the ad-hoc network. | 12-02-2010 |
20100304759 | METHOD AND APPARATUS FOR ENGAGING IN A SERVICE OR ACTIVITY USING AN AD-HOC MESH NETWORK - An approach is provided for discovering a location-based service over an ad-hoc mesh network. A location-based service is discovered sending an anonymous flooding message including a query over the ad-hoc mesh network. A wireless node replies to the flooding message over the ad-hoc mesh network with a pointer to the discovered location-based service. | 12-02-2010 |
20100306320 | METHOD AND APPARATUS FOR LOCATING COMMUNITIES OVER AN AD-HOC MESH NETWORK - An approach is provided for locating communities over an ad-hoc mesh network. Community identifiers are used to locate communities and community members over an ad-hoc mesh network. The community identifiers are also associated with keys to authenticate members of the community and to protect the privacy and anonymity of information exchanged between the members. | 12-02-2010 |
20110219423 | METHOD AND APPARATUS FOR TRIGGERING USER COMMUNICATIONS BASED ON PRIVACY INFORMATION - An approach is provided for protecting a user identity in communication based on privacy information. The privacy engine selects one or more parameters associated with a privacy metric. Next, the privacy engine determines the parameters in a communication environment, the communication environment including a user device and a plurality of other devices. Next, the privacy engine computes a privacy level based, at least in part, on the parameters and the privacy metric. Next, the privacy engine compares the computed privacy level against a predetermined privacy level. Then, the privacy engine triggers a communication to one or more of the other devices in the communication environment based, at least in part, on the comparison. | 09-08-2011 |
20120243408 | METHOD AND APPARATUS FOR PROVIDING A COLLABORATIVE REPLY OVER AN AD-HOC MESH NETWORK - An approach is provided for providing a collaborative reply to a flooding message over an ad-hoc mesh network. A reply message to a flooding message is received by a wireless node within the ad-hoc network. The wireless node monitors for an acknowledgement of receipt of the reply message according to a routing table and initiates a scheduled transmission of the reply message based on the monitoring. | 09-27-2012 |
20120314660 | METHOD AND APPARATUS FOR LOCATING COMMUNITIES OVER AN AD-HOC MESH NETWORK - An approach is provided for locating communities over an ad-hoc mesh network. Community identifiers are used to locate communities and community members over an ad-hoc mesh network. The community identifiers are also associated with keys to authenticate members of the community and to protect the privacy and anonymity of information exchanged between the members. | 12-13-2012 |
20140019763 | METHODS AND APPARATUS FOR AUTHENTICATION - Message authentication in an ad-hoc network. Upon creation of a message, a message authentication code is created using a key shared with members of a group comprising a subset of nodes of the ad-hoc network. The message authentication code may be created using a cryptographic process having the message and a message identifier as inputs. After or in parallel with broadcast of the message, a pointer to the message is broadcast. The message authentication code is publicly broadcast and those members of the group among which the key has been shared are able to authenticate the message as coming from a particular sender. | 01-16-2014 |
20140122882 | METHODS AND APPARATUS FOR DATA SECURITY IN MOBILE AD HOC NETWORKS - Systems and techniques for key management in mobile ad hoc networks are described. Pseudonyms are defined for group members of mobile ad hoc networks such that a pseudonym in a message can be deterministically identified with the sending device only by the sending device and the message recipient. Key management for a group is performed by a group manager, and key management may include key renewal and revocation. Key renewal is performed by a group manager, with the group manager using a set of couple pseudonyms, including a couple pseudonym between the manger and each group member. Key renewal employs a renewal key used to encrypt the updated group key, and the group manager updates the group key be transmitting a message to each group member in proximity, with the message being identified using the couple pseudonym of the manager and the group member. | 05-01-2014 |
20140349684 | METHOD AND APPARATUS FOR PROVIDING A COLLABORATIVE REPLY OVER AN AD-HOC MESH NETWORK - An approach is provided for providing a collaborative reply to a flooding message over an ad-hoc mesh network. A reply message to a flooding message is received by a wireless node within the ad-hoc network. The wireless node monitors for an acknowledgement of receipt of the reply message according to a routing table and initiates a scheduled transmission of the reply message based on the monitoring. | 11-27-2014 |
