摘要:
An event collection method collects an event from a sensor network, the method includes: retrieving on a per process basis for a module, based on a module definition information and an occurred event information, an occurrence node identifier categorized by an attribute value corresponding to an attribute name, with input event type associated with an occurred event type; determining, when there is a single retrieved occurrence node identifier with respect to the process of the module, a node identified by the occurrence node identifier as an installation destination of the module that is identified by the module identifier; referencing, when there is a plurality of retrieved occurrence node identifiers with respect to the process of the module, a connection relation information of nodes and determining an upper node common to the plurality of occurrence node identifiers as an installation destination of the module identified by the module identifier.

摘要:
An authentication checking server makes user authentication checking when an access is made to an individual in-house server. A resource managing server receives a resource request corresponding to the resource of the individual server, calculates the access right to the corresponding resource based on the resource request and the result of the authentication checking, and relays the calculated access right and the resource request to the individual server. Upon receipt of the access right and the resource request, the individual server transmits the resource as a mobile code. A client machine receives and executes the mobile code, whereby an encryption access is made to the resource of the individual server included in an in-house network via the relay agent generated within the client machine.

A mobile node is arranged to perform a high-quality hand-over operation for eliminating an interruption time in communication and keeping the continuance of communication excellent. The mobile node has a function of interfacing with networks and includes a network quality monitor, a hand-over controller, and a network controller. The network quality monitor operates to monitor a network quality based on at least one of an intensity and a radio bandwidth of a radio wave received by network devices. The hand-over controller performs the hand-over operation of transmitting a care of address to an address registering destination in response to a state of the network quality before a communication is disconnected, changing a route of communication information, and switching a connecting destination into a new network. The network controller receives a response that indicates an update of the care of address in the address registering destination and keeping a function of receiving data from the network before being switched until the communication is disconnected.
