In the rapid growth environment, internet plays a vital role in each and every one's life. As to reach high performance communication in the network, electronic devices are the most important element to forward multimedia messages from one place to another place. Whenever unaccountable messages are passing from one node to another node there are heavy collision and congestion in the network because...
Named Data Networking is a new data centric kind of communication network. This paper shows the study about NDN network and applies this architecture over Vehicular ad-hoc networks so that performance of network improves and communication becomes faster. At the end of simulation results are discussed in the form of packet delivery ratio, throughput, good put, routing overhead and various network parameters...
MANETs is collection of wireless network establishing a network in which nodes communicate with each other by network systems such as the Internet. MANETs routing protocols are characterized into two types, for example, table-driven and on-request or demand. In this network node performed as a function of routers which discovers and maintain the path to other node. In Adhoc network nodes are easily...
We present a simulation-based study of the impacts of channel switching overhead on the performance of multicast in multi-channel multi-radio wireless mesh networks (MCMR WMNs). We study how channel switching overhead affects the performance metrics such as packet delivery ratio, throughput, end-to-end delay, and delay jitter of a multicast session.
Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers, because of their potential use in several fields such as collaborative computing and communications. In this paper, we present the implementation of a testbed for WMNs using Raspbian OS. We analyze the performance of Optimized Link State Routing (OLSR) protocol in an indoor environment considering Transmission...
Mobile ad hoc network is wireless network that employ multi-hop radio relayed and are capable of achieving without the support of any fixed infrastructure. The cut of any central coordinator makes the routing more complex. All nodes of these networks behave as routers and take part in discovery and maintenance of routes to other nodes in the network. This characterstic presents a big challenge to...
Ambient intelligence (AmI) deals with a new world of ubiquitous computing devices, where physical environments interact intelligently and unobtrusively with people. AmI environments can be diverse, such as homes, offices, meeting rooms, schools, hospitals, control centers, vehicles, tourist attractions, stores, sports facilities, and music devices. In this paper, we present the design and implementation...

A Mobile ad hoc network consists of wireless mobile nodes those who have ability to communicate mutually while there is no role of infrastructure network or any centralized control. In order to forward packets from one node to another, a mobile node works as host as well as router. Routing protocols play a relevant role in functioning of mobile ad-hoc networks. Many routing protocols have been proposed...

Software Defined Networking (SDN) is an emerging phenomenon in computer networking. SDN splits control element and forwarding element of a network. It has characteristics such as centralized management, programmability, more security, granularity and reliability. Therefore SDN is suitable for data center, cloud computing and carrier networks. As reliability and fault tolerance are main concerns, these...
In this paper, we have extended the GeoDivRP geodiverse routing protocol to consider jitter requirements when using multiple geographic paths for telecommunication networks under regional challenges. We have formulated bounded-jitter multipath routing using a multi-commodity flow problem and proposed an integer linear programming formulation to solve it. We have implemented the routing protocol in...
In mobile ad hoc network due to the limited transmission range of wireless nodes, multiple hops are needed to exchange information between nodes in the network. Thus routing is a crucial issue to design of a Mobile Ad-Hoc Network. So, there is need of efficient routing protocols to establish communication paths between nodes, without causing extreme control traffic overhead or power constrained devices...
Vehicular safety applications intended for VANETs. It can be separated by inter-vehicle communication. It is needed for a vehicle can travel safety with high velocity and must interconnect quickly dependably. In this work, examined the impact of the IDM-IM and IDM-LC mobility model on AODV, AOMDV, DSDV and OLSR routing protocol using Nakagami propagation model and IEEE 802.11p MAC protocol in a particular...
Classical WMNs work in single-radio single-channel (SR-SC) architecture in which one network interface card (NIC) is deployed in each router and one common radio channel is shared by every mesh router. In this architecture, network endures from low capacity and throughput due to frequent back offs and packet collisions, hence single-radio multiple-channels (SR-MC) had been designed to enhance the...
Wimax is an broadband wireless technology based on IEEE 802.16. It is very helpful and cheaper than other possible solutions. It is purely based on the 4G technology for the upcoming generation. In wireless technology the major problem is speed, Quality of Service, data rates in order to overcome that they going for some valuable technology. In this paper we consider WIMAX and WLAN for controlling...
In MANET, all nodes are mobile in nature and having limited battery charge. Continuous change in position and connection degrades the battery charge of the nodes therefore it is necessary to save battery of those nodes which are having low battery so that the network lifetime can be long lasting. It is really very significant to increase lifetime of MANET. In order to enhance the lifetime of MANET;...
A mobile ad hoc network (MANET) is an infrastructure less and self-configuring network of mobile devices which dynamically form a network without the help of any centralized administration. Frequently changing network topology needs efficient dynamic routing protocols. The performance of any routing protocol depends on the duration of interconnection among the nodes in the network for transferring...
Quality of service (QoS) in wireless mesh networks is an active area of research which is driven by the increasing demand for multimedia content delivered wirelessly. The IEEE 802.16 (WiMAX) standard identifies four classes of service targeting throughput, delay, and jitter. In this paper, we achieve two main objectives. (1) We present a routing metric sensitive to both interference and throughput...
In this paper we propose the channel assignment scheme for multi-channel wireless mesh network (WMN), where each mesh router is equipped with multiple radio interfaces. In real WMN the number of radio interfaces is much higher than the number of non-overlapping channels, which causes a lot of connections between mesh nodes operate on the same radio channel. Increasing number of simultaneous transmissions...
