40、ity requirements (FCR) of sensor networks, there are additional unique requirements that the intelligent sensor networks have to meet the challenges from intrinsic environment complexity, large orders of magnitude network scaling and dynamic application requirements. Environmental self-adaptability:

41、 An intelligent sensor network shall adapt to obtain required system performances if the physical environment of the sensor networks monitoring area changes. For example, an intelligent sensor network based anti-intrusion system should guarantee consistent system performances such as detection and f

42、alse alarming rate (FAR) when the environment in which the sensor network is deployed changes. Dynamic task supporting: An intelligent sensor network shall support dynamic tasking including dynamic task assignment, dynamic task ordering by prioritization, dynamic service provisioning for information

43、 users/consumers, and dynamic quality of service (QoS) adjustment. Autonomous system maintenance: An intelligent sensor network shall autonomously maintain system functionalities in case of network scaling, node mobility, new node entrances, node exits, and node failures.5.3 Overview of collaborativ

44、e information processingThe key differences between traditional telecommunication infrastructures and information service systems based on sensor networks are that (1) sensor networks systems collect raw sensory data from physical world; and (2) from these data, extract application-specific informat

45、ion in order to obtain feature level data, decision level information, and knowledge about the physical world.Integrated with metadata such as sensory information description, sensor identification, and sensory information location, CIP handles efficient resource management to provide the dynamic ta

46、sking to fulfil the requests demanded by information service consumers. Though different sensor network applications normally require application-specific services, the collaborative processing is an indispensable requirement for senor network based information service to handle constraints in power

47、 (e.g. batteries), computing resources, storage, and communication bandwidth. The collaborative processing also has to deal with technical challenges such as task dynamics, measurement uncertainty, node mobility, and environmental adaptation ability.The aims of CIP in sensor networks are to improve

48、system efficiency, enhance quality of service, and guarantee system performance. It provides efficient mechanisms such as majority-voting fusion, decision template fusion and statistical methods for handling incomplete and/or inaccurate information. It also provides protocols to meet challenges from

49、 intrinsic environment complexity, large orders of magnitude network scaling and dynamic application requirements.CIP can be viewed from three distinct viewpoints.
