摘要：A wireless sensor network (WSN) is a composed group of a small tiny battery-equipped device capable ofsensing, communication and computation which can be scattered over a vast region for the purpose of detecting ormonitoring region perfectly. Sensing coverage and network connectivity are two of the most fundamental problem inWSNs. In WSN is usually defined as a measure of how well the sensing field is monitored or sensors are able to observe thephysical space. Connectivity can be defined as the ability of the sensor to reach the data sink. Finding an optimaldeployment strategy that provides high degree of coverage with network connectivity is extremely challenging. Therefore,maximizing network coverage as well as maintaining network connectivity using the resources constrained node is a nontrivialproblem. In this survey article, we classify the coverage problem; analyze the relationship between coverage andconnectivity and research challenges and existing problem in this area.
