When analyzing dissemination protocols in mobile ad-hoc networks the underlying mobility model is an important factor because it strongly influences the performance of these protocols. So far most of the research only dealt with homogeneous mobility models like the very common Random Waypoint Mobility Model and the Random Walk Mobility Model. In this paper we introduce a new model, the Area Gra...

background and purpose: diabetes has adverse effects on the quality of life of patients. roy’s adaptation model could be used to enhance quality of life among diabetic patients. this study aimed to evaluate the effects of roy’s adaptation model in nursing practice on the quality of life in patients with type ii diabetes. methods: this quasi-experimental study was conducted on 60 diabetic patien...

Despite the long history of modelling human mobility, we continue to lack a highly accurate approach with low data requirements for predicting mobility patterns in cities. Here, we present a population-weighted opportunities model without any adjustable parameters to capture the underlying driving force accounting for human mobility patterns at the city scale. We use various mobility data colle...

Performance of routing protocols in mobile ad-hoc networks is greatly affected by the dynamic nature of nodes, route failures, wireless channels with variable bandwidth and scalability issues. A mobility model imitates the real world movement of mobile nodes and is central component to simulation based studies. In this paper we consider mobility nodes which mimic the vehicular motion of nodes l...

Among the aspects that require a major interest in the simulation of mobile ad hoc networks (MANETs) is the mobility of nodes in the network. Several mobility models have been proposed. In this paper, we study the impact of self-organized behavior based models on the mobility of nodes in the network, through two models, namely: Flock Mobility model and Leadership mobility Model. The results are...

poverty alleviation programs is the most important of the public sector policies. design effective a policy for poverty reduction is requires the identifying time change socio-economic characteristics of households. if we want to investigate and evaluate the effects of specific supportive policies and programs in the field of poverty entail the measurement of poverty changes over time. income m...

Flying Ad-Hoc Networks (FANETs) is a group of Unmanned Air Vehicles (UAVs) which completed their work without human intervention. There are some problems in this kind of networks: the first one is the communication between (UAVs). Various routing protocols introduced classified into three categories, static, proactive, reactive routing protocols in order to solve this problem. The second proble...

Abstract: The movement pattern of mobile producer plays an important role in mobility performance analysis the wireless and network. However, behavior is directly affecting handoff latency signaling overhead cost. Many researchers provide analytical investigation to analyze solve problems compared with simulation result. To justify between investigation, node needs be included make it possible ...

Mobility is regarded as a network transport mechanism for distributing data in many networks. However, many mobility models ignore the fact that peer nodes often carried by people and thus move in group pattern according to some kind of social relation. In this paper, we propose one mobility model based on group behavior character which derives from real movement scenario in daily life. This pa...
