The deployment strategy for wireless sensor networks (WSNs) affects the quality of service (QoS). Adopting a reasonable can improve QoS WSNs. In this paper, problem regarding node WSNs on three-dimensional (3D) terrain is modeled as multi-objective optimization problem. coverage rate WSNs, their unbalanced energy consumption, and number nodes are used fitness functions We propose non-dominated ...

Let Sn be the set of all permutations on [n] := {1, 2, . . . , n}. We denote by κn the smallest cardinality of a subset A of Sn+1 that “covers” Sn, in the sense that each π ∈ Sn may be found as an order-isomorphic subsequence of some π′ in A. What are general upper bounds on κn? If we randomly select νn elements of Sn+1, when does the probability that they cover Sn transition from 0 to 1? Can w...

Infrastructure-based indoor geolocation systems utilizing a regular grid arrangement of sensors are being investigated for many applications in indoor wireless networks. One of the factors affecting the Quality of Estimation (i.e. location estimation accuracy) of these systems is node density. In this dissertation we study the effects of node density on indoor geolocation systems based on time ...

introduction: neglecting to define important criteria in developing a basic health insurance package and to notice their real roles will result in defining a package which is politically unacceptable, non-economical, technically inefficient or mixed of them. therefore development of basic health insurance package should be according to appropriate composition of influential criteria. this study...
