Exposure in Wireless Sensor Networks: Theory and Practical Solutions
Wireless ad-hoc sensor networks have the potential to provide the missing interface between the physical world and the Internet, thus impacting a large number of users. This connection will enable computational treatments of the physical world in ways never before possible. In this far reaching scenario, quality of service can be expressed in terms of accuracy and/or latency of observing events and overall state of the physical world. Consequently, one of the fundamental problems in sensor networks is the calculation of coverage, which can be defined as a measure of the ability to detect objects within a sensor filed. Exposure is directly related to coverage in that it is an integral measure of how well the sensor network can observe an object, moving on an arbitrary path, over a period of time. After elucidating the importance of exposure, we formally define exposure and study its properties. We have developed an efficient and effective algorithm for exposure calculation in sensor ne...
