Energy consumption has been a key concern of data gathering in wireless sensor networks. Previous research works show that modulation scaling is an efficient technique to reduce energy consumption. However, such technique will also impact on both packet delivery latency and packet loss, therefore, may result in adverse effects on the qualities of applications. In this study, the problem of modu...

Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...

background: depression is a kind of sorrow that decreases the level of juiciness. most studies have maintained that psy­chological risk factors have the most profound effect on the development of postnatal depression (pnd). we compared the postnatal depression among the women with elective caesarean and vaginal delivery.  methods: this cross- sectional study was carried out on 120 women 1-4 mon...

Dynamic networks, e.g. Mobile Ad Hoc Networks (MANETs), call for self-healing routing protocols to tolerate topological changes imposed by node mobility. Moreover, emerging time-critical MANET applications such as disaster response and rescue, and battlefield operations, require support for real-time, reliable data streaming, while maintaining energy efficiency. However, most of the energy-effi...

Securing the energy delivery system (EDS) from complex, nonlinear, and evolving cyber threats requires a complex set of changing interwoven classes technologies, policies, relationships, personnel. One key area in this technological milieu is assessment methodologies to compare information, gathered by variety means, about networked devices with publicly known possible threat information said d...

Mobile devices have become important companions to most people, and are increasingly used for work and/or entertainment, most of the time consuming multimedia content. Diverse Quality of Service (QoS) metrics help estimate the enduser perceived quality or Quality of Experience (QoE) of the multimedia delivery to these mobile devices. However, energy consumption and device battery lifetime are a...

A sensory network consists of multiple detection locations called sensor nodes, each of which is tiny, featherweight and portable. A single path routing protocols in wireless sensor network can lead to holes in the network, since only the nodes present in the single path is used for the data transmission. Apart from the advantages like reduced computation, complexity and resource utilization, t...
