A monitoring system having an ad-hoc network of wireless sensor stations. Each sensor station is provided with one or more sensors suitable for monitoring one or more physical parameters of interest and collecting information. The sensor stations are configured to process the collected information using appropriate distributed computational algorithms such that nearby sensor stations can exchange information with each other in the ad-hoc network to evaluate the situation in a specific location at a specific moment in time employing combined information of the nearby sensor stations in the area. The information is transmitted via the ad-hoc network to information consumers only if necessary, based on the evaluation.

1. A method, comprising: setting up an ad-hoc network of wireless sensor stations to monitor an area, wherein at least some of the sensor stations comprise one or more sensors suitable for monitoring one or more physical parameters of interest,collecting information using said sensors;providing the collected information with spatial and temporal information;processing the collected information using appropriate distributed computational algorithms such that at least two nearby sensor stations exchange information with each other and at least one of the sensor stations provides distributed processing to at least one other nearby sensor station in response to an inquiry in said ad-hoc network to evaluate the situation in a specific location at a specific moment in time employing combined information of said at least two nearby sensor stations in the area, including said spatial and temporal information;determining roles of the sensor stations in the information collecting and the distributed processing at runtime by sensor stations themselves according to the data requests made to the network and the capabilities, locations and properties of the sensor stations; andtransmitting, if required based on the evaluation, information on the situation via said ad-hoc network to information consumers. 2. The method of claim 1, further comprising: at least one of the sensor stations inquiring information and/or distributed processing from at least one other nearby sensor station in response to a predetermined triggering event. 3. The method of claim 1, further comprising: at least one of the sensor stations sending information and/or providing distributed processing to at least one other nearby sensor station in response to a predetermined triggering event. 4. The method of claim 1, further comprising: determining the roles of the sensor stations in the information collecting and the distributed processing at runtime, depending on the availability of algorithms, the availability of processing power, the availability of energy, the requirements of the application, the properties of sensor stations and/or requirements of other sensor stations. 5. The method of claim 1, further comprising: a sensor station executing a specific distributed processing algorithm or a specific information collecting task in response to a specific request from another node. 6. The method of claim 1, further comprising: updating the processing algorithms of a sensor station during operation of the sensor station via the ad-hoc network. 7. The method of claim 1, further comprising: transmitting only collaboratively processed information or decisions to the information consumers outside the ad-hoc network. 8. The method of claim 1, further comprising: transmitting information to the information consumers outside the ad-hoc network, when a decision to transmit information has been made by at least one of the sensor station as a result of evaluating information collected by at least two sensor stations. 9. The method of claim 1, further comprising: transmitting information to the information consumers, when a decision to transmit information has been made by more than one of the sensor stations, based on the information collected, processed and forwarded by said more than one sensor stations and possibly other sensor stations in the area. 10. The method of claim 1, further comprising: at least one sensor stations querying, processing and analyzing information collected and processed by at least one nearby sensor station,at least one sensor station assessing the situation in a certain area at a certain time employing information collected locally and information collected by other sensor stations,at least one sensor station tagging the queries and information with temporal and spatial information for monitoring and evaluating the source of an event in the location of sensors at various locations and with various modalities, anda sensor station evaluating the situation in a specific location at a specific moment in time, employing the information collected by the sensor station itself and by other sensor stations in the area. 11. The method of claim 1, wherein the information consumers include one or more of the following: a command centre, a patrol system, a security centre, a data processing centre, a mobile user terminal, a control room of a plant, a maintenance system of a plant. 12. A system, comprising: an ad-hoc network of wireless sensor stations set up to monitor an area,each of the sensor stations including a processor unit, a wireless communication unit and one or more sensors suitable for monitoring and collecting sensor information regarding one or more physical parameters of interest, the collected sensor information being provided with spatial and temporal information;the processor units of the sensor stations processing the collected sensor information using appropriate distributed computational algorithms to evaluate the situation in a specific location at a specific moment in time employing combined sensor information of at least two nearby sensor stations in the area, including said spatial and temporal information;the processor units of the sensor stations being configured to determine roles of the sensor stations in the information collecting and the distributed processing at runtime based on data requests made to the network and the capabilities, locations and properties of the sensor stations; andthe sensor stations being configured to transmit, if required based on the evaluation, information on the situation via said ad-hoc network to information consumers. 13. A sensor station, comprising one or more sensors suitable for monitoring one or more physical parameters of interest, a wireless communication module, a computing unit, and a memory for storing data, wherein said sensor station is configured to set up an ad-hoc network with a plurality of other similar sensor stations to monitor an area and to collect sensor information provided with spatial and temporal information;the computing unit of the sensor station processing the collected sensor information in collaboration with the other sensor stations using appropriate distributed computational algorithms to evaluate the situation in a specific location at a specific moment in time employing combined information of the sensor station and the at least one nearby sensor station in the area, including said spatial and temporal information;the computing unit of the sensor station determining the role of the sensor station in the information collecting and the distributed processing at runtime based on data requests, capabilities, locations and properties of the other sensor stations.
