In this paper, we present a minimum spanning tree (MST)-based algorithm, called local (LMST), for topology control in wireless multihop networks. each node builds its LMST independently and only keeps on-tree nodes that are one-hop away as neighbors the final topology. We analytically prove several important properties of LMST: 1) derived under preserves network connectivity; 2) degree any resulting is bounded by 6; 3) can be transformed into one with bidirectional links (without impairing...
Underwater acoustic sensor networks (UASNs) have become more and important in ocean exploration applications, such as monitoring, pollution detection, resource management, underwater device maintenance, etc. In networks, since the routing protocol guarantees reliable effective data transmission from source node to destination node, design is an attractive topic for researchers. There are many algorithms been proposed recent years. To present current state of development UASN protocols, we...
Topology control algorithms usually reduce the number of links in a wireless network, which turn decreases degree connectivity. The resulting network topology is more susceptible to system faults such as node failures and departures. In this paper, we consider k-vertex connectivity network. We first present centralized algorithm, Fault-tolerant Global Spanning Subgraph (FGSSk), preserves FGSSk min-max optimal, i.e., minimizes maximum transmission power used among all that preserve Based on...

Most existing topology control algorithms assume homogeneous wireless networks with uniform maximal transmission power, and cannot be directly applied to heterogeneous where the power of each node may different.
