Contact between mobile hosts and database servers presents many problems in the Mobile Database System (MDS). It is harmed by a variety of causes, including handoff, inadequate capacity, frequent transaction updates, repeated failures, both which contribute to serious issues with information system’s consistency. However, error tolerance technicality allows devices continue performing their fun...

Wireless sensor networks consists of nodes that are connected via wireless links and collaborate to self-organize into a network without utilizing any centralized infrastructure. Sensor encompass wide range paradigms from this research study focuses on the mobile networks, which recently significant potential for public/commercial environments emergency disaster management services. Despite hyp...

The sinkhole attacks for Internet of Things (IoT) situations can overcome the network and interrupt communication. Sinkhole attacker nodes advertise best possible shortest path towards destination, once normal node starts transferring packets by given path, troublemaking flow network. In this environment, destination is unable to receive proper information or may not complete information. attac...

Growing experimental evidence indicates that, in addition to the physical virion components, the non-structural proteins of hepatitis C virus (HCV) are intimately involved in orchestrating morphogenesis. Since it is dispensable for HCV RNA replication, the non-structural viral protein NS2 is suggested to play a central role in HCV particle assembly. However, despite genetic evidences, we have a...

Cytopathogenicity of Bovine viral diarrhea virus (BVDV) is correlated with expression of the nonstructural protein NS3, which can be generated by processing of a fusion protein termed NS2-3. For the cytopathogenic (cp) BVDV strain Oregon, NS2-3 processing is based on a set of point mutations within NS2. To analyze the correlation between NS2-3 cleavage and cytopathogenicity, a full-length cDNA ...

In Intelligent Transport Systems, traffic management and providing stable routing paths between vehicles using vehicular ad hoc networks (VANET's) is critical. Lots of research several techniques a long path lifetime have been presented to resolve this issue. However, the algorithms suffer excessive overhead or collisions when solving complex optimization problems. order improve efficiency perf...

This paper presents a Dynamic Reconfiguration of Mobile IP Agents (DRMIPA) and failure free architecture integrated in Mobile Ad hoc Networks (MANETs). The proposal is due to the fact that: actual infra-structured networks do not implement the Mobile IP (MIP) protocol, all MIP agents are static and the cost of having redundancy for MIP agents’ failure is often high. As MANETs are created tempor...

The central focus of this paper is mobile ad hoc networks (MANETs) and their security. Key distribution is a major challenge in this dynamic type of network. A novel mechanism called Direct Indirect Trust Distribution (DITD) is proposed to secure key distribution for an on-demand ad hoc routing protocol. The solution includes a trust evaluation and representation mechanism. A security evaluatio...

As the enormous use of internet increases day by day so as security concern is also raise day by day over the internet. In this paper we discuss the network security and its related threats and also study the types of protocols and few issues related to protocols in computer networks. We also simulate the design of 5 node wired network scenario, its packet drop rate analysis through TCP protoco...

Worldwide Interoperability for Microwave Access (WiMAX) is currently one of the hottest technologies in wireless, it‟s a standard-based on the IEEE 802.16 wireless technology that provides high throughput broadband connections over long distance, which supports Point to Multi-point (PMP) broadband wireless access. This paper presented an analysis on those routing protocols especially designed f...
