摘要： A multi-tone synchronous collision resolution system permits communication nodes within a MANET to contend simultaneously for a plurality of available channels. The communication nodes contend for access using a synchronous signaling mechanism that utilizes multiple tones in a synchronous manner to resolve contentions. Contentions are arbitrated locally, and a surviving subset of communication nodes is selected. The communication nodes of the surviving subset then transmit data packets simultaneously across the available communication channels.

摘要： Application programming interfaces and methods that provide graph management in a peer-to-peer (P2P) network are provided. More specifically, new and improved P2P application programming interfaces (APIs) and methods for the creation and access of graphs, the retrieval of node and graph information, the addition, modification, deletion and management of records (data), the importation and exportation of graph data, the direct communication between graph nodes, the addition of a security provider to a graph, the setting and retrieval of presence information, the registering for event notifications, and other utility and support functions are presented. Each of these interfaces utilize various parameters that are passed in from an application program that uses these interfaces to manage and utilize graphs. The interfaces return a value that indicates the success or failure of the function. For failures, the interfaces provide an indication as to the problem resulting in the failure.

摘要： A system, apparatus, method, and computer-readable medium are provided for authorizing a computing node to participate in a group of computing nodes utilizing a shared group password. According to one method described herein, an invitation to join a group is transmitted to a tentative group member node. The invitation is used to establish a connection with a group member node of the group. The tentative group member node generates a hash of a group password and transmits the hash to the group member node. When the group member node receives the hash, the group member node compares the received value to a previously stored hash of the group password. If the previously stored value is identical to the value received from the tentative group member node, then the tentative group member node is authorized as a new member of the group. Otherwise the tentative group member node is not permitted to become a member of the group.

摘要： A collaborative services platform may include a connectivity service, an activity service and a contact management service. The connectivity service may provide communicative connectivity between users of the collaborative services platform. The activity service may provide one or more collaborative activities supporting various modes of communication. The contact management service may maintain contact information for each of the users of the collaborative service platform. It may be that not every user is capable of participating in every collaborative activity. The contact information maintained by the contact management service may indicate the collaborative activities in which each user is capable of participating. A set of programmatic objects utilized to implement the collaborative services platform may include contact objects, conference objects, MeContact objects, endpoint objects, published objects and presence objects. The presence object may represent a presence of a particular user in a networked computing environment and may reference multiple collaborative endpoints.

摘要： A security infrastructure and methods are presented that inhibit the ability of a malicious node from disrupting the normal operations of a peer-to-peer network. The methods of the invention allow both secure and insecure identities to be used by nodes by making them self-verifying. When necessary or opportunistic, ID ownership is validated by piggybacking the validation on existing messages. The probability of connecting initially to a malicious node is reduced by randomly selecting to which node to connect. Further, information from malicious nodes is identified and can be disregarded by maintaining information about prior communications that will require a future response. Denial of service attacks are inhibited by allowing the node to disregard requests when its resource utilization exceeds a predetermined limit. The ability for a malicious node to remove a valid node is reduced by requiring that revocation certificates be signed by the node to be removed.

摘要： A method of reducing glare may include sensing a first light source with a second vehicle, and sensing a second light source with a first vehicle and oscillating a first light source ICF between a substantially opaque state and a substantially clear state on a first schedule. A second windscreen ICF may be oscillating between the substantially opaque state and the substantially clear state on a second schedule different from the first schedule. A position of the light source may be sensed and an eye position of the occupant estimated. An intersecting region of the selectively-darkenable ICF, which is located substantially along a line from the position of the light source to the eye position, is calculated. The intersecting region of the ICF is darkened, such that a reduced amount of light from the light source passes through the intersecting region.

摘要： Systems and methods are described that facilitate the management of contact information, at least some of the contact information related to entities in a serverless, peer-to-peer system. A contact store may store information regarding which other entities of a plurality of other entities are authorized to monitor presence of a user entity. Presence of an entity may generally indicate the willingness and/or ability of the entity to communicate and/or collaborate with other entities, for example. The contact store may also store information regarding which other entities of the plurality of other entities the presence of which should be monitored by the system. A user entity may be able to add contacts to and/or delete contacts from the contact store, for example. The user entity may also be able to modify the contact store to modify which other entities are authorized to monitor presence of the user entity and/or which other entities the presence information of which should be monitored by the system, for example.
