Wireless sensor network (WSN) is an emerging research field in recent years. The advancement in sensory device and communication technologies has enabled the deployment of diverse sensor networks such as random network consisting of thousand sensors or carefully deployed deterministic network. Despite the plethora of applicability of sensor networks, there are some limitations too such as energy efficiency, lifetime, coverage, localization etc. As the sensor nodes are battery driven so conservation of energy becomes crucial in the hazardous applications. Coverage is also considered as the major quality of service (QoS) metric which aim to maximize the observation quality of the target region. Several approaches have been proposed in the literature to address the coverage problem but most of the approaches have the same objective to achieve the maximum lifetime while ignoring the QoS parameters. The real world applications of WSN require addressing of several QoS parameters too such as reliability, throughput, delay in packet transmission etc. This review paper provides the exhaustive study of the coverage problem concepts, issues and challenges. The paper provides the classification of coverage approaches especially related to that of target coverage. The paper provides a comprehensive comparison of different categories of target coverage approaches. The paper also discusses the future research direction in the field of target coverage which also considers the QoS considerations.
