A notable requirement of clusters is to maximize its processing performance. Lots of work in this area has been done to optimize the system performance by improving certain metric such as reliability, availability, security and so on. However, most of them assumes that the system is running without interruption and seldom considers the system’s intrinsic characteristics, such as failure rate, r...
In order to prolong the network lifetime, energy-efficient protocols should be designed to adapt the characteristic of wireless sensor networks. Clustering Algorithm is a kind of key technique used to reduce energy consumption, which can increase network scalability and lifetime. This paper studies the performance of clustering algorithm in saving energy for heterogeneous wireless sensor networ...
The results of three-dimensional numerical simulations of mass transfer in semide-tached binaries after mass transfer termination is presented and the structure of residual accretion disk was investigated. It was shown that after the mass transfer termination the quasi-elliptic accretion disk becomes circular. It was also shown that the cessation of mass transfer results in changing of the stru...
In Wireless Sensor Networks (WSNs), sensor nodes are organized in a random manner. These sensor nodes are mainly deployed in physical environment to gather data and deliver the data to the destination wherever requires. Sensor nodes have limited computational capability, limited bandwidth, energy source and memory. The main challenge in data gathering is to maximize the network lifetime and the...
Abstract We introduce a new generalized family of nonnegative continuous distributions by adding two extra parameters to lifetime distribution, called the baseline twice compounding power series distribution. The family, series-power has serial arrangement parallel structures, which extends Marshall and Olkin structure. Four special models are discussed. A mathematical treatment is provided, in...
It is known that for decreasing hazard rate (DHR) service times the foreground– background discipline (FB) minimizes the mean delay in the M/G/1 queue among all work-conserving and nonanticipating service disciplines. It is believed that a similar result is valid for increasing mean residual lifetime (IMRL) service times. However, on the one hand, we point out a flaw in an earlier proof of the ...
Clustering provides an effective method for improving the performance of wireless sensor networks (WSNs). In this paper, we study that different number of clusters leads to different network performance on the energy consumption, energy balancing and network lifetime. We propose an Energy-Efficient Multi-hop Hierarchical Routing Protocol (MHRP) for wireless sensor networks to enhance the networ...
