Abstract: A platform may receive raw data from a remote system and may then applies various forms of analysis to convert the raw data into parameters of interest in a garden. These parameters include but are not limited to soil moisture, soil salinity, air temperature, soil temperature, and pH. The platform enables inexpensive and simple sensors to be deployed in the garden. The platform may also use other data, such as the data from a weather service, to predict actions that should be taken in the garden to provide optimal growing conditions.

Abstract: A remote sensor platform may utilize a low-cost touch sensor coupled to capacitive plates to measure the capacitance of a soil. The sensor platform may also use other sensors to measure other garden parameters, such as soil resistance, soil pH, ambient light, soil or air temperature, and humidity. Based on measurements of a soil's resistance and capacitance, the soil moisture content may be determined.

Abstract: A remote platform receives and analyzes a set of desired garden parameters that is to be emulated or recreated in a first garden. The desired garden parameters may be measured by sensors installed in a second garden. The desired garden parameters may include soil moisture, soil salinity, soil temperature, soil pH, external temperature, external humidity, and light exposure. The remote platform then generates a data set based on its analysis of the desired garden parameters. The data set includes instructions to open or close a first sprinkler valve, add fertilizer, apply mulch, and provide covering. The data set may be transmitted to a user associated with the first garden, a controller hub controlling sprinkler valves in the first garden, sprinkler valve controllers installed in the first garden, or sensor-controller hybrids installed in the first garden.

Abstract: A system and method for locating a wireless client using trusted wireless detectors is described. Sniffers may sense signal strength information and transmit the information to a database. The database may store signal strength-based location information. Information from the database may then be used to determine the location of a wireless client based on new signal strength information from one or more sniffers.

Abstract: A system and method that uses wireless-capable desktop computers in a vicinity such as to enable one to securely determine the location of an untrusted user with office level granularity.

Abstract: The invention is addressing the problem of efficient formation and maintenance of piconets with assistance from the master of an already existing piconet. The master of an existing piconet initiates the formation of a new helper piconet by at least two of its slaves. One of the slaves of the existing piconet becomes the master of the newly formed helper piconet and the other slave becomes a slave of the helper piconet. This process can be used to expand the number of Bluetooth devices that can use an Internet access point. It can also be used to permit two slave devices to communicate directly with one another so as not to unnecessarily use bandwidth available through the master. Finally, the method and system could be used to provide a method of efficient hand-off from one piconet to another.

Abstract: The present invention, among other things, obviates the effects of an attack on a wireless network through appropriate isolation and recovery. An aspect of the present invention can include a system and method of isolating a victim of malicious behavior in a wireless access network, and in particular WLAN networks. By having software on the victim's device, the system provides the capability of recovering the victim from the effects of the intruder, and prevents the victim from being affected by subsequent attacks by the intruder. The preferred embodiments include two key components: a local monitor and a global monitor.

Abstract: A method and apparatus for controlling ingress to a communications network to control quality of service is described. A request to admit a new communications flow is received. A polynomial and its coefficients representing a state of the network is determined and applied to the network state plus the new communications flow to determine whether admission of the new communications flow would cause the network to operate in a stable or unstable state. In response to determining that the network would operate in the unstable state, a communications flow for the ingress device is downgraded in its quality of service. By another approach, it is determined whether the new communications flow exceeds an allocated quota of bandwidth. Admission or rejection of the communications flow can be determined.

Abstract: Our invention is a method and system for a method of providing Quality of Service (QoS) over networks that do not provide any information and only serve to carry packets. Specifically, as Traffic traverses between various user networks via an opaque network, gateways at the edge of the user networks keep a record of the packets traversing into the opaque networks and packets traversing out of the opaque network. These gateways also know about the traffic classes that each of these packets belong to. The gateways at the ingress points (the user network where the packets originate) and the gateways at the egress points (the user network where the packets terminate) coordinate amongst themselves to exchange information about the number and latency of packets exchanged between the two. This information is used by the gateway at the ingress to estimate the state of the opaque network using dynamic throughput graphs.

Abstract: A secure localization method for wireless networks utilizes access point variable transmission power capability to transmit encoded localization signals at different power levels to a wireless device in the network. Based on the particular combination of encoded signals collected by the wireless device and reported back to a network controller, the location of the wireless device may be determined in conjunction with information contained in a location database.

Abstract: A system for key management in sensor networks which takes the location of sensor nodes into consideration while deciding the keys to be deployed on each node. This system reduces the number of keys that have to be stored on each sensor node and also provides for the containment of node compromise. Thus compromise of a node in a location affects the communications only around that location. The location dependent key management system does not require any knowledge about the deployment of sensor nodes. The system starts off with the loading of a single key on each sensor node prior to deployment. Subsequent to deployment a plurality of beacons is transmitted a plurality of different transmission ranges from each anchor node, said beacons containing at least one nonce. Each sensor node receives beacons depending upon its location in the network.
