MONITORING METHOD, A MONITORING SYSTEM AND A SENSOR STATION
First Claim
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; and
transmitting, if required based on the evaluation, information on the situation via said ad-hoc network to information consumers.

Abstract
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.
