As the users on the cloud network increase, the consumption of the Compute, Network and Storage resources also increases. This leads to increase in the cost of deployment, configuration and maintenance. Hence, the Capital Expenditure (CAPEX) of the organization providing the cloud network increases. Network Function Virtualization (NFV) is a technology which virtualizes network functionalities. This...
The era of networking has moved from dedicated physical network devices to the abstraction of functional software component of those network devices. The functional software component can be run as a software image on any hardware platform. Routers are vital components in any networking environment which routes the information to different networks spread over a geographical area. VyOS is a software...
As the users on the cloud network increase, the consumption of the Compute, Network and Storage resources also increases. This leads to increase in the cost of deployment, configuration and maintenance. Hence, the Capital Expenditure (CAPEX) and Operational Expenditure (OPEX) of the organization providing the cloud network increases. Network Function Virtualization (NFV) is a technology which virtualizes...
Directional communication in Mobile Ad-hoc Networks (MANETs) helps in mitigating the problems of exposed nodes and interference, while providing better spatial reuse. However, use of directional antenna also leads to the problem of deafness. This paper presents a novel method to mitigate deafness in MANETs. In the proposed method, Request To Send (RTS), Clear To Send (CTS), Data and Acknowledgement...
Routing is an essential part of data exchange in Mobile Ad-hoc Networks (MANETs). A protocol that can discover multiple routes from source to destination can support reliable routing of information in MANETs. However, a reliable routing protocol alone cannot enhance performance of MANETs. Nodes in MANETs also experience the problems of interference, exposed nodes and deafness. Hence a solution that...
Due to increasing popularity of Mobile Ad hoc Networks (MANETs), research in this area has constantly strived to improve performance of these networks. In this paper Dual Polarized Directional Antenna based Medium Access Control (DPDA-MAC) protocol is presented to enhance the throughput of MANETs. Nodes operating in accordance with DPDA-MAC are capable of simultaneously using orthogonal (vertical...
Constant monitoring of patient's health is essential to provide appropriate healthcare. With advances in electronic circuit miniaturization and micro-electromechanical systems (MEMS), wearable sensor nodes can be used to acquire physiological signals from patient's body and transmit them to a remote location which can be accessed by the doctors. Wireless Sensor Networks (WSNs) are becoming an integral...
Mobile Ad-hoc Network (MANET) is a collection of mobile nodes which can self-organize freely and dynamically into arbitrary and temporary network topologies. Mobile nodes in ad-hoc networks can dynamically establish routes among themselves by means of a routing protocol. Therefore, selection of an appropriate routing protocol is an integral part of establishing a MANET. Apart from the choice of routing...
Wireless ad-hoc networks have attracted immense research interest in the past few years. Most of the research has concentrated on the performance of routing protocols in ad-hoc networks. Apart from routing, it is also important to study the protocols used at transport layer such as Transmission Control Protocol (TCP) and User Data gram Protocol (UDP) and their effect on data propagation in ad-hoc...
