    Abstract: —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.
