In this work we design a virtual backbone to provide energy-efficient communication in Wireless Sensor Networks (WSNs). WSNs need virtual backbones to support in-network data transmission. In scenarios where there is no spatial redundancy (such as a sensor network in a petroleum installation), Connected Dominating Set (CDS)-based algorithms can be useful for hierarchical network management. We construct...
Topology management protocols play an important role in WSNs, managing the sleep transitions of the nodes to make data transmissions occur in an energy-efficient way, thus prolonging network lifetime. However, classical topology management protocols are not suitable for real-time WSNs, as they may introduce unbounded delays. In a previous work, we presented a static topology management protocol specifically...
Wireless sensor networks can monitor physical and environmental conditions inexpensively, and the networks have been widely used in military and civilian applications. The sensor nodes in the networks not only have the ability to sense, but also can supply data storage, computation and communicate with each other. However, energy efficiency is the major concern in wireless sensor networks, which usually...
