Service-oriented wireless sensor networks have recently been proposed to provide an integrated platform, where new applications can be rapidly developed through flexible service composition. In wireless sensor networks, sensors are periodically switched into the sleep mode for energy saving. This, however, will cause the unavailability of nodes, which, in turn, incurs disruptions to the service compositions...
How to adjust the transmission power at each node to achieve global energy efficiency while maintaining the network connectivity, referred as power management problem, is the major target of various topology control technologies. Moreover, fault tolerance which is often modeled as 2-edge or 2-vertex connectivity is another desired feature in many applications. In this paper, we study the fault tolerant...
One of the basic operations in a wireless sensor network is the enquiry and transmission of sensed data from sensor devices in some specified regions to the data center for further processing. A key challenge in data enquiring and transmitting is to minimize the total energy cost occurring at all sensor nodes involved. In this paper, we introduce and study the energy efficient data enquiring problem...
