Topology control is a fundamental issue in wireless ad hoc and sensor networks. Due to
intrinsic characteristic of flatness, hierarchical topology can achieve the scalability and …

The connected dominating set (CDS) has been a classic subject studied in graph theory
since 1975. It has been discovered in recent years that CDS has important applications in …

Inspired by the backbone concept in wired networks, virtual backbone is expected to bring
substantial benefits to routing in wireless sensor networks (WSNs). Virtual backbone …

Abstract In a Wireless Sensor Network (WSN), neither there is any fixed infrastructure nor
any centralized control. Therefore, for efficient routing, some of the nodes are selected to …

In wireless sensor network, a connected dominating set (CDS) can be used as a virtual
backbone for efficient routing. Constructing a minimal CDS (MCDS) is good for packet …

Wireless sensor networks (WSNs) are used to cover destination areas for a lot of practical
applications. To enhance the performance of the WSN, the virtual backbone based on the …

High-density seismic array method has attracted enormous interest in geophysical methods,
and it is an advanced seismic observation technology which is of great significance in oil …

Topology control is relevant in wireless sensor network because of two reasons, namely
minimal sensor coverage and power constraints. The former condition is typically satisfied …

For improving the efficiency and the reliability of the opportunistic routing algorithm, we
propose a cross-layer and reliable opportunistic routing algorithm (CBRT) for mobile ad hoc …

Topology management schemes have emerged as promising approaches for prolonging the
lifetime of the wireless sensor networks (WSNs). The connected dominating set (CDS) …
