Vijay Kumar, JECET; June 2017- August 2017; Sec. B; Vol.6. No.3, 102-107, [DOI: 10.24214/jecet.B.6.3.10207]

Abstract

In today’s environment wireless networks have given an extensive variety of utilizations making it conceivable to effectively interconnect gadgets and frameworks which have the remote association office, for example, mobile telephones, tablets, portable PCs and so on all around the globe. In present days Internet protocols shows wasteful execution in those networks where the availability between end nodes has irregular property because of dynamic topology, for example, Mobile Ad-hoc Networks (MANET) or Vehicular Ad-hoc Networks (VANET). The network conditions where the nodes are portrayed by opportunistic availability are alluded to as Delay Tolerant Networks (DTNs). DTNs have been one of the developing territories of premium described by the huge measure of research endeavors put resources into this region over the previous decade. Routing is one of the significant issues influencing the general execution of DTN networks as far as asset utilization, information delivery and dormancy. In the course of recent years various routing protocols have been proposed for DTN networks. In this paper fundamentally three DTN routing protocols: Direct Delivery, Epidemic Routing and Spray and Wait Routing, are pushed and looked at as far as Average Packet Delivery Probability and Average Latency.

Abstract

Cloud computing is a technology that provides various kinds of services to the user as per their need. Various benefits associated with cloud environment are reliability, scalability, security etc. This paper gives light on various service models and cloud platforms that are present in the market for the user’s requirement. This paper is basically divided into four sections: Section 1 gives a brief introduction about Cloud Computing whereas section 2 explains various service models deployed on cloud, section 3 illustrates various platforms of cloud. The section 4 concludes the summary by illustrating various differences between various platforms of cloud.

Abstract

The nucleus of every software system is its design architecture. Software design is a demanding task that requires lot of experience, expertise, and knowledge of many different types of design alternatives. Each software engineers acquires more specific knowledge as he/she participate in a new project. Experienced engineers are very vital asset to Software Company, especially in a high competitive market environment; as such reusing knowledge of experienced engineers can save a lot of cost and time to the software company. UML models are a de facto used by many software engineers during the software design stage, its receiving a widespread attention in the field of software reuse. It’s not surprising, because of the benefits that can be reaped out during the reuse of early software design is numerous, and it can leads to reuse of all related work-products down-stream the software development process. There are considerable amount of works that takes place within the scope of software designs reuse, this paper presents state of the art on the current approaches of software designs reuse. To do this, papers related to UML-models based reuse published in literature are extracted from the most relevant scientific sources (ScienceDirect, IEEE Computer society, Scopus database, and Google Scholar) were considered.

An insight into Assistive technology and tools for PWD (People with disabilities)

Shikha Mishra and Mr. Ravi Prakash Chaturvedi, JECET; June 2017- August 2017; Sec. B; Vol.6. No.3, 080-086.,[DOI: https://doi.org/10.24214/jecet.B.6.3.8086]

Abstract

This paper highlights the assistive technology and tools for people with disabilities. These tools ensures to equal access of websites and application to everyone irrespective to mental and physical challenges. This paper also discusses the methods and approaches to ensure web accessibility compliance. We also look at a few code examples. The paper mainly focuses on Assistive Tools available for PWDs like Screen Reader that can help improve the accessibility compliance of a websites.

Performance Evaluation of AODV Routing Protocolm

Nidal AbidAl-Hamid Al-Dmour, JECET; June 2017- August 2017; Sec. B; Vol.6. No.3, 71-79.,[DOI:10.24214/jecet.B.6.3.7179]

Abstract

A wireless LAN is a LAN that uses the air as a medium of transmission to permit data transmission among fixed, or moving computers. Wireless LANs operates either in infrastructure or Mobile Ad hoc mode. In infrastructure mode, devices are connected over the air to an AP which in turn connected to a wired network. Ad hoc mode does not require any central to operate. There are two different types of routing protocols for Mobile Ad hoc Networks (MANET): Reactive and Proactive. Ad-Hoc On-demand Distance Vector (AODV) is an example of Reactive routing protocol and in this paper we studied its performance by using Omnet++ simulator and INET simulation model.
