Abstract: Now a day’s Cloud computing is a complex and very rapidly evolving and emerging area that affects IT infrastructure, network services, data management and storage resources and applications. And because of this nature it is drawing much attention from academia and industry. Many vendors provide Infrastructure as a Service, Software as a Service, and Platform as a Service. Different vendors have implemented different architectures for their SaaS, IaaS and PaaS clouds. In order to give a vision of cloud computing architecture in this paper I present the different architectures that I studied including layered architecture, modelled architecture, reference architecture, virtualization architecture and network architecture.

Abstract: In 21st century networks act as backbone of world to perform various task given to it. Adhoc network (MANET) is major part of netwok.But MANET is a dynamic network without the fixed infrastructure due to their wireless nature and topology changes due to their dynamic nature .Among various protocol used as routing protocol in the MANET the AODV is most popular and widely used due to their various beneficial characteristics .But its beneficial characteristics will degrades when Nodes or links fails as it sends the error message back to the source and whole process is repeat again. In this paper we had successfully developed an protocol that enhanced the major drawback of AODV during its nodes and links fails as compared to previous proposed algorithms .And thus it will also enhances the feature like throughput ,reliability , security , packet size ,overheads ,traffic congestion. )
