The paper describes the concept of coverage problem in the wireless sensor networks (WSNs). The issue of quality of service is more closely related to the coverage problem in WSNs. The motive behind the coverage problem is to have the supervision of at least one node at every point of targeted region. Efficient coverage can be defined as the network lifetime by describing the features like sensing ability and energy consumption by sensing nodes. The covering strategies based on Computational Geometry are discussed and various other strategies have been elaborated.read more
