Secure Routing Environment with Enhancing QoS in Mobile Ad-Hoc Networks

A mobile adhoc network is infrastructure-free and self configured network connected without wire. As it is infrastructure-free and no centralized control, such type of network are suitable only for conditional inter communication link. So initially maintaining Quality of Service and security aware routing is a difficult task. The main purpose of QoS aware routing is to find an optimal secure route from source to destination which will satisfy two or more QoS constrain. In this paper, we propose a net based multicasting routing scheme to discovery all possible secure path using Secure closest spot trust certification protocol (SCSTC) and the optimal link path is derived from Dolphin Echolocation algorithm (DEA). The numerical result and performance analysis clearly describe that our provided proposal routing protocol generates better packet delivery ratio, decreases packet delay reduces overhead in secured environment

Energy Aware Routing Protocol for Energy Constrained Mobile Ad-hoc Networks

Dynamic topology change and decentralized makes routing a challenging task in mobile ad hoc network. Energy efficient routing is the most challenging task in MANET due to limited energy of mobile nodes. Limited power of batteries typically use in MANET, and this is not easy to change or replace while running communication. Network disorder can occur for many factors but in middle of these factors deficiency of energy is the most significant one for causing broken links and early partition of the network. Evenly distribution of power between nodes could enhance the lifetime of the network, which leads to improving overall network transmission and minimizes the connection request. To discourse this issue, we propose an Energy Aware Routing Protocol (EARP) which considers node energy in route searching process and chooses nodes with higher energy levels. The EARP aim is to establish the shortest route from source to destination that contains energy efficient nodes. The performance of EARP is evaluated in terms of packet delivery ratio, network lifetime, end-to-end delay and throughput. Results of simulation done by using NS2 network simulator shows that EARP can achieve both high throughput and delivery ratio, whereas increase network lifetime and decreases end-to-end delay

Разработка механизма адаптивной маршрутизации трафика в программно-конфигурируемых сетях

The purpose of this work is to develop a unitary mechanism of adaptive routing of different kinds, basing on the current requirements on the quality of service. The software configuration of a network is the technology of the future. The trend in communication systems constantly confirms this fact. However, the application of this technology in its current form is justified only in large networks of technology giants and telecom operators. Today we have a large number of dynamic routing protocols to route big volume traffic in communication networks. Our task is to create the solution that can use the opportunities of each node to make a decision on the transmission of information by all possible means for each type of traffic. Achieving this goal is possible by solving the problem of the development of generalized metrics, which details the links between devices in the network, and the problem of establishing a framework of adaptive logical network topology (route management) to ensure the quality of the whole network in order to meet the current requirements on the quality of a particular type service.Цель данной работы – разработать единый механизм адаптивной маршрутизации трафика различного рода, опираясь на текущие требования к качеству предоставления сервисов.Программное конфигурирование сети – это технологии будущего. Современная тенденция развития систем связи постоянно подтверждает этот факт. Однако на сегодняшний день применение этой технологии в ее текущем виде оправдано лишь в больших сетях технологических гигантов и операторов связи. К настоящему времени создано большое количество динамических протоколов маршрутизации трафика в сетях связи. Наша задача создать такое решение, которое сможет использовать возможности каждого узла принимать решение о передаче информации всеми возможными способами для каждого типа трафика. Достижение поставленной цели возможно путем решения задачи разработки обобщенной метрики, подробно характеризующей каналы связи между устройствами в сети, и задачи разработки механизма адаптивного перестроения логической топологии сети (управления маршрутами) для обеспечения качественной работы всей сети в целях удовлетворения текущим требованиям к качеству предоставления того или иного вида сервиса
