In survival analysis and reliability theory, the mean past lifetime (MPL), arises in situations where time elapsed since failure of a component T, given that it has failed before t, is interest. For inference on MPL function, some procedures have been proposed literature for function's estimator. this paper, an empirical likelihood (EL) procedure function developed. addition to that, we obtain ...

This paper presents an energy-efficient loadbalancing algorithm for Wireless Sensor Networks. The algorithm specifies that only the nodes which have residual energy above a threshold can take part in routing, and that residual energy is to be updated at the highest opportunistic rate supported by the network. The algorithm was tested on and showed improvements to hierarchical data aggregation a...

Clustering is an effective approach for managing nodes in Wireless Sensor Network (WSN). A new method of clustering mechanism with using Binary Gravitational Search Algorithm (BGSA) in WSN, is proposed in this paper to improve the energy consumption of the sensor nodes. Reducing the energy consumption of sensors in WSNs is the objective of this paper that is through selecting the sub optimum se...

In this paper a weighted version of Adya distribution which includes has been suggested for modeling lifetime data. The natures descriptive statistics including coefficients variation, skewness, kurtosis, and index dispersion have studied. reliability measures hazard rate function, reversed mean residual life function stochastic ordering Method maximum likelihood estimation discussed estimating...

network sensors consist of sensor nodes in which every node covers a limited area. the most common use ofthese networks is in unreachable fields.sink is a node that collects data from other nodes.one of the main challenges in these networks is the limitation of nodes battery (power supply). therefore, the use oftopology control is required to decrease power consumption and increase network acce...

Recently, there has been growing interest in alternative measures of uncertainty, including cumulative residual entropy. In this paper, we consider a mixed system consisting n components, assuming that all components are operational at time t. By utilizing the signature, able to compute entropy system’s remaining lifetime. This metric serves as valuable tool for evaluating predictability We stu...
