摘要—Target Tracking is one of the most important issues in
wireless sensor networks. In a densely deployed wireless sensor
networks (WSNs), all sensors participating in the monitoring task
can provide full coverage but might inefficiently consume their
energies if the target did not enter the region. This paper proposes an
energy-saving and quality-guaranteed target tracking mechanism,
called EQTT, which dynamically wakes up sensors in a distributed
manner, aiming to minimize the number of working sensors while
the user-defined tracking quality can be satisfied. The proposed
EQTT mainly consists of two phases: the network initialization
phase and target tracking phase. The first phase aims to wake up
minimal number of boundary sensors whose sensing range is
intersected with the boundary of the monitoring region M. These
working sensors can construct barrier coverage for the boundaries of
M and all the other sensors stay in sleep state for energy
conservation. When the target is detected by the boundary sensors,
the target tracking phase is automatically initiated, which aims to
further wake up minimal number of neighboring sensors of the
detected sensor but satisfy the user-defined tracking quality.
