Binary grey wolf optimisation-based topology control for WSNs
IET Wireless Sensor Systems, 2019 Wireless sensor networks (WSNs) are composed of a large number of sensor nodes that are deployed at target locations. Topology control (TC) is one of the significant fundamental challenges in WSNs because of node energy and computing power constraints ...

On minimal self-joinings in topological dynamics [PDF]
Ergodic Theory and Dynamical Systems, 1987 AbstractIf X is a compact metric space and T a homeomorphism of X we say (X, T) has almost minimal power joinings (AMPJ) if there is a dense GδX* in X such that for each finite set k, x∈(X*)k and l:k → ℤ−{0}, the orbit closure cl {} is a product of off-diagonals (POOD) on Xk. By an offdiagonal on Xk′, k′k we mean a set of the form (⊗,j∈k′Tm(j))Δ, Δ the

Positivity relations on a locale [PDF]
, 2016 This paper analyses the notion of a positivity relationof Formal Topology from the point of view of the theory of Locales. It is shown that a positivity relation on a locale corresponds to a suitable class of points of its lower powerlocale.

Real-Time Spatial Queries for Moving Objects Using Storm Topology
ISPRS Int. J. Geo Inf., 2016 With the rapid development of mobile data acquisition technology, the volume of available spatial data is growing at an increasingly fast pace. The real-time processing of big spatial data has become a research frontier in the field of Geographic ...

On Valency-Based Molecular Topological Descriptors of Subdivision Vertex-Edge Join of Three Graphs [PDF]
Symmetry, 2020 In the studies of quantitative structure–activity relationships (QSARs) and quantitative structure–property relationships (QSPRs), graph invariants are used to estimate the biological activities and properties of chemical compounds. In these studies, degree-based topological indices have a significant place among the other descriptors because of the ...

Distributed Multi-Agent Hierarchy Construction for Dynamic DCOPs in Mobile Sensor Teams
Human-Centric Intelligent Systems, 2023 Coordinating multiple agents to optimize an objective has several real-world applications. In areas such as disaster rescue, environment monitoring and the like, mobile agents may be deployed to work as a team to achieve a joint goal.

The Bi-Compact-Open Topology on C(X)
, 2016 For the set C(X) of real-valued continuous functions on a Tychonoff space X, the compact-open topology on C(X) is a "set-open topology". This paper studies the separation and countability properties of the space C(X) having the topology given by the join

An Efficient Tree-Based Self-Organizing Protocol for Internet of Things
IEEE Access, 2016 Tree networks are widely applied in sensor networks of Internet of Things (IoTs). This paper proposes an efficient tree-based self-organizing protocol (ETSP) for sensor networks of IoTs.

Flows and joins of metric spaces
, 2005 We introduce the functor * which assigns to every metric space X its symmetric join *X. As a set, *X is a union of intervals connecting ordered pairs of points in X. Topologically, *X is a natural quotient of the usual join of X with itself. We define an
