One of the major functions of a Wireless Sensor Network (WSN) is to provide the coverage to the network area. Many critical applications require different levels of coverage in the different parts of the network area which is generally called differential coverage. Providing differential coverage service in different period of time is a challenging due to the limited capabilities of the network nodes...
Coverage and connectivity are two important performance evaluation indices for wireless sensor network (WSNs). In this paper, we focus on the connected target k-coverage (CTCk) problem in heterogeneous wireless sensor networks (HWSNs). A distributed connected target k-coverage algorithm (DCTCk) is proposed in order to generate connected cover sets for energy efficient connectivity and coverage maintenance...
Coverage is an important metric used to measure the quality of service of three-dimensional wireless sensor networks (3D WSNs) monitoring a field of interest (FoI). While it is important to ensure the desired level of coverage, it is also necessary to do so with a minimum number of sensors from a network cost perspective. In this paper, we assume that the sensors are deployed at random uniformly in...
Coverage and connectivity are the key research questions in wireless sensor networks, the relationship of which is very closely. One of the traditional methods for solving Coverage and connectivity is integer programming algorithm, whose research background is homogeneous wireless sensor networks and single coverage. The method can not satisfy the requirements in actual high-precision target detection...
This paper mainly studies the problem of connected coverage control in wireless sensor networks and proposes a strategy called CCSL (connected coverage strategy based on logistic layers) based on the relationship of coverage and connectivity. The strategy adopts the logistic layers to solve coverage and connectivity problems independently. By doing this, CCSL can achieve the optimization of both connectivity...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
