The present disclosure generally pertains to systems and methods for controlling sensor networks. A sensor network has a plurality of sensor nodes, which have sensors for monitoring operational parameters of devices within an application-specific system. A wireless communication module is provided for each node to enable the node to wirelessly communicate with other nodes of the network. A user defines various scripts for controlling the behavior of one or more nodes, and the network distributes the scripts, as appropriate, to various nodes thereby implementing the behavior defined by the scripts. Accordingly, a user can easily and dynamically configure or re-configure the behavior of any node without having to physically access the node that is being configured or re-configured.

Systems and methods for dynamically configuring node behavior in a sensor network

The present disclosure generally relates to systems and methods for controlling nodes in a communication network, such as a wireless sensor network. In one exemplary embodiment, a node, referred to herein as a 'coordinator node,' controls the operation of various nodes, referred to herein as 'sensor nodes,' that are configured to monitor various parameters. The coordinator node from time-to-time broadcasts a beacon to the sensor nodes. The beacon can include various information that is used by the sensor nodes for control. In one exemplary embodiment, the beacon includes node-specific information that informs at least some nodes that they are to transition to a sleep state for a certain period of time. Such nodes, based on the beacon, transition to a sleep state, thereby conserving electrical power.

Systems and methods for controlling sleep states of network nodes

One embodiment includes a system for application-layer monitoring of communication between one or more database clients and one or more database servers. The system includes one or more decoders residing at a decoding layer above a network layer. The decoders reside at a first network location between one or more database clients residing at one or more second network locations and one or more database servers residing at one or more third network locations. The decoders receive database messages communicated from the database clients and intended for the database servers and database messages communicated from the database servers and intended for the database clients, decode the database messages, and extract query-language statements from the database messages. The system also includes a monitoring application residing at an application layer above the decoding layer. The monitoring application resides at the first network location. The monitoring application receives query-language statements extracted at the decoders and records observations on the database messages based on the query-language statements extracted at the decoders.
