An ad-hoc network has a provision of Quality of Service (QoS) to support many applications like digital and multimedia applications. However, one of the challenging tasks in ad-hoc network is Quality of Service (QoS) which is determined by numerous parameters such as bandwidth, delay constraints, varying channel conditions, power limitations, node mobility, dynamic topology, packet ...

Several routing protocols have been proposed in recent years for possible deployment of Mobile Ad hoc NETworks (MANETs) in military, government and commercial applications. In this paper, the authors review these protocols with a particular focus on security aspects. The protocols differ in terms of routing methodologies and the information used to make routing decisions. ...

In this paper, the authors present the review of the various existing and recently proposed location privacy preserving techniques in Wireless Sensor Networks (WSNs) against a local as well as global eavesdropper. Knowledge of the network topology in Local eavesdropper is limited while global eavesdropper can analyze the overall traffic pattern. Privacy preservation techniques are ...

Though, cloud offers sophisticated storage and access environment. It is not hundred percent reliable; the challenge exists in ensure the authoritative access. Since third parties formulate the decision concerning their data, security is a big concern. So cloud is required to ensure that the data accessed is by the trusted users. Cloud computing uses multi-domain ...

Big data is a collection of data sets which is very large in size as well as complex. Generally size of the data is Petabyte and Exabyte. Every organization has big data. This big data contains structured, semi structured and unstructured data. Social networking users are increasing so the data of the social networking sites ...

TCP (Transmission Control Protocol) congestion management is finish to finish management mechanism. That is enforced through dominant some important parameter amendment scrutiny to wireless networks, there are many various characteristics in wireless environments. In this paper, enhanced mechanism for transmission management protocol TCP protocol communications protocol corruption control is presented. It considers the influences to ...

Ad hoc is wireless, in dependable infrastructure dynamic and self-organize network creates among different mobile host. Network generally exists in a Disaster recoveries, military activities emergency operation. Routing protocol has a major role in mobile network, which are affected from different attacks. Ad hoc On demand Distance Vector (AODV) routing protocol is suitable for routing ...

Mobile wireless sensor network is a subset of mobile ad hoc network. Therefore independent nods mobility is an essential property of network. The proposed routing protocol is implemented and simulated in NS2 network simulation environment. In order to simulate the routing performance using two different network scenarios the performance is compared. And the comparative performance ...
