In accordance with an example embodiment of the present invention, there is provided an apparatus, comprising a receiver configured to receive sensor data, a transmitter configured to cause the sensor data, or data derived at least in part from the sensor data, to be transmitted, wherein the transmitter is further configured to transmit a metadata request to a first node. In some embodiments, the apparatus is a sensor node for inclusion in a sensor network, the sensor node capable of measuring at least one physical property to produce the sensor data.

Method and apparatus for managing sensor information

Various methods for distributing a single stream of sensor data to one or more services are provided. One example method may include maintaining an association between sensor data and one or more services requesting the sensor data. The method of this example embodiment may further comprise receiving the sensor data. The example method may further comprise generating one or more copies of the sensor data. The example method may also comprise providing for distribution of the copies of the sensor data to the services requesting the sensor data, such that a copy of the sensor data is provided for distribution to each of the services requesting the sensor data. Similar and related example methods, example apparatuses, and example computer program products are also provided.

Method and apparatus for distributing sensor data

In accordance with an example embodiment, there is provided an apparatus, comprising a receiver configured to receive from a second apparatus over a first radio interface a first message comprising a registration request, a transmitter configured to transmit a second message to the second apparatus over the first radio interface, the second message comprising an acknowledgement of the registration request, and a processor configured to reserve an interface identifier for the second apparatus, wherein the processor is configured to not allow the reserved interface identifier to be used by further nodes over at least one further radio interface.

Method and apparatus for managing radio interfaces

A method, apparatus, and computer program product are provided for making network optimization decisions based on observed network node performance information. Network nodes may continuously report performance measurement information to network servers. Observers may request registration with the servers and access to the mode measurement information. The observer may specify a measurement threshold that, when met, causes the server to report node measurement data to the observer. The node measurement data enables the observer to make network optimization and control decisions. An optimal radio frequency might be selected; a node might switch between different gateways or cause a handoff from one gateway to another for efficient traffic routing. A user could observe measurement data for friends and receive notice when friends are in close proximity or engaged in like activity such that a social contextual community might be formed.

Decision making based on remote observation of node capabilities

A method, apparatus and computer program product are provided to proxy communication between different types of networks, such as different types of networks that communicate in accordance with different protocols or different messaging patterns. In the context of a method, communication is supported with a content-centric network having one or more clients that are configured to communicate with publish and subscribe messages. The method also supports communication with one or more nodes configured to communicate in an Internet domain, such as by supporting communication with a CoAP network or a HTTP network. The method also proxies communicating between one or more clients of the content-centric network utilizing the publish and subscribe messages and one or more nodes in the Internet domain using an Internet domain message.

Method for proxying communication between a content-centric network and an internet domain

Various methods are described for determining a communications window for served nodes and internal applications in order to optimize power consumption. One example method may comprise determining a communications window for a plurality of served nodes. The method of this embodiment may also include causing the communications window to be signaled to the plurality served nodes. The method of this embodiment may also include causing a communications interface to be activated during the communications window in an instance in which at least one packet is received for at least one served node of the plurality of served nodes.

Method and apparatus for transmission synchronization utilizing a router advertisement

An incoming data packet is received, and a rate of change of residual capacity of a portable power supply is determined. From the determined rate of change it is decided to enqueue or drop the incoming data packet. If the decision is to enqueue, the packet is transmitted. If the decision is drop, the packet is deleted without transmitting. Additional factors may be considered in the decision, such as total energy capacity, residual energy capacity, and first and second derivatives of the residual energy capacity. Real time traffic may be treated differently than non real time traffic, and video enhancement layer packets can be weighted to drop more frequently than video base layer packets for the same flow. If used in the network, congestion probe packets are dropped at a rate matched to the rate at which data packets are dropped to give other nodes an accurate view of link quality.
