Advancement in computing technologies and increasing demand of computing resources (such as network, storage, servers, applications etc.) has made cloud computing as main computing basis for small or large IT enterprises. The enterprises which are not able to establish their own infrastructure and resources are taking help of different (Infrastructure as a Service) IaaS service providers on basis...
In the present scenario, an energy efficiency has become a matter of prime importance for wireless networks. To meet the demands of an increased capacity, an improved data rate, and a better quality of the service of the next-generation networks, there is a need to adopt energy-efficient architectures. Along with these requirements, it is also our social responsibility to reduce the carbon footprint...
The network topology in Mobile Ad hoc Networks (MANETs) dynamically changes due to mobility of nodes and power constrained, hence routing is a challenging issue in these networks. QoS aware routing is needed to provide optimal routes as a function of parameters like bandwidth, delay, packet loss etc. Our approach is focused on QoS enabled route discovery procedure which involves estimation of node...
With the introduction of different wireless communication technologies, the demand of users for real time services like voice along with data called VoIP is increasing tremendously. In order to provide high quality services, the new technologies like WiMAX have to consider all the quality parameters attached with a service. Thus, the paper discusses the WiMAX support to such services along with all...
In last decayed a big revolution has been done in the communication and network industry and in presence scenario cloud computing has been playing a significant role for last one year. Since user or client preferred flexibility to acquired any network on the basis of bandwidth, QoS (Quality of service) and Cost i.e. cost should be proportional to demand and uses of data. In this paper we have given...
Security has grown to be a major concern in regulate to provide restricted communication in Wireless as well as wired environment. As far as security concern related to WiMAX network i.e for PHY Layer (Jamming and scrambling) and MAC Layer attack protection has been provided by (AES, PKM etc) one separate Layer(Security Layer). In current scenario Network Layer security is more vital and we have analyzed...
We proposed WiMAX and WLAN interface technology for Location Based Radio Resource Allocation (LBRRA). Since as quality of technology increase demand is also increases with human nature. In this paper we are given solution for replacement of optical fiber (Fiber to Home) for internet. Our proposed solution has been reduced cost significantly for next generation networks (NGN).In this proposed solution...
There has been ongoing debate regarding the use of voltage overscaling along with error resilience techniques for ultra low power operation of scaled CMOS logic. The issue is whether to build enough design margin into future electronic systems so that errors do not impact the Quality of Service of the end application or to allow errors to occur and correct them using error tolerance mechanisms. Specific...
