Distance estimation is fundamental for many functionalities of wireless sensor networks and has been studied intensively in recent years. A critical challenge in distance estimation is handling anisotropic problems in sensor networks. Compared with isotropic networks, anisotropic networks are more intractable in that their properties vary according to the directions of measurement. Anisotropic properties...
In this paper, we propose a new control method to cover ldquoholesrdquo in wireless sensor networks. Many applications often face the problem of holes when some sensor nodes are disabled from the collaboration due to their failures and misbehavior. These holes may occur dynamically, and such a problem cannot be solved completely by simply deploying more redundant sensors. With synchronization around...
Good sensor deployment is vital for wireless sensor networks (WSNs). To improve the initial deployment and to prolong network lifetime, one approach is to relocate sensors in different densities which vary with the distance to the sink. Since sensors located closer to the sink are involved in more data forwarding, sensors in this region should have a higher density. In this paper, we address the problem...
