In Mobile Adhoc networks (MANET) the mobility of nodes results in regular and random changes of network topology, which results in regular route changes, network partitions and possibly packet losses, making routing a challenging task in MANET network. The mostly used routing protocols in such networks are proactive and reactive routing protocols, but a reactive routing strategy is the most popular...
Wireless mesh network (WMN) is a peculiar type of growing technology that can alter the world more effectively in the coming decades. Multicast routing in mesh networks is the distribution of data from a single source to multiple destinations or multiple sources to multiple destinations through the intermediate nodes. There can be many numbers of intermediate nodes between source and destination....
Wireless Sensor networks (WSN) is basically comprised of sensors that are spatially distributed with self-ruling capability, which monitors physical or environmental conditions such as, pressure, temperature, motion, sound and so on. Sensors also passes all the related information throughout the network. As the number of nodes and size of the network increases, there will be rapid increase in internet...
In the last years with according to the increasing application of wireless sensor networks in military, space, medicine, safety, fields and etc, many methods and algorithms have been represented to improve the quality of routing. But according to existence limits in this network, the representative methods aren’t properly responsible and the goals should be improved. Our goal is that we should prepare...
The article gives such a parameter as the priority of node in the routing system of a telecommunication network. The given parameter is proposed to be considered in risk assessment of route information security.
Due to the rapid acceleration of computing technology in internet, billions of hosts are to be successfully handled by the network layer of TCP/IP Protocol suite during data communication. Design of a highly efficient and consistent protocol at IP service layer along with managing heterogeneous sub networks having multiple technology is a challenging task. In this paper we present reliable network...
Ad hoc wireless networks are influence embarrassed because nodes function through restricted battery energy. Therefore, Energy expenditure is central propose of new ad hoc routing protocols. To propose such protocols we contain to give the impression of being missing from the conventional minimum hop routing schemes. Moreover, limited-energy property makes together nodes and network lifetime surrounded...
Internet technology and multimedia applications practices increasing day by day, a stimulation of Quality of Service (QoS) in Mobile Ad hoc Networks (MANETs) is now a great interest area for companies to serve better for their users. This research work focuses on design and development of new Energy Aware Multicast Cluster (EAMC) based routing to enhance the QoS of the MANETs. This proposed routing...
The traditional ant routing protocol provides an efficient way for dynamic routing in continuously changing networks. Due to their social behaviour, ants tend to find optimized paths based on network status information such as the path length and capacity. However, the conventional ant routing protocol tends to satisfy acceptable Quality of Service (QoS) requirements for the whole network traffic...
Mobile ad hoc Networks (MANETs) is a type of wireless ad hoc network which is a self-arranging network of mobile nodes connected by wireless links that create a discretionary topology. The mobile nodes are free to move randomly and to arrange themselves in a random manner. Thus, the wireless ad hoc network topology may expand rapidly and unpredictably. In Mobile ad hoc networks, the routing protocol...
Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. ZigBee is the real time application for the WSN used for low-cost data and energy consumption characteristics. ZigBee is a robust network certain application of which has come out with a critically low designation for less data rate, long delivery delay and...
A Wireless cellular Ad-hoc network is a collection of wireless mobile hosts that makes a momentary network with or without a centralized management or wired infrastructure. This is the era of growing smart phone technology people are dependent on the service provided by phone so in this scenario providing quality of service is essential task for service providers. Smart phone is movable device user...
Planning and evaluating a Network on Chip (NoC) for a specific application is usually a complex task that requires the collaboration of both hardware and software specialists. Predicting the performance of the devised architecture and solution is both difficult in nature and time consuming. In this paper we present a high level model for five-port router based NoCs using Matlab's SimEvents toolbox...
Mobile Ad hoc network (MANET) is a special type of network that supports connectivity without any infrastructure and it faces many challenges such as high mobility rate of the nodes, resource constraint and the nodes work without any central administration. In Mobile Adhoc Network (MANET), the mobile devices have restricted resources such as limited battery power, so it is difficult for traditional...
Sensor nodes depend on power source, but they deplete rapidly. The major issues of Wireless Sensor Network (WSN) are its energy source constraints. We are able to solve this issue by using clustering architecture. In this paper we study about various clustering techniques used in WSN. The large-scale deployment of WSNs and the need for data aggregation resolve this issue mainly. Clustering is best...
For intermittently connected mobile networks, many hybrid routing protocols combined conventional mobile ad hoc networking (MANET) routing with Delay Tolerant Networking (DTN) approach, have been proposed. These protocols transfer data quickly in networks. They transfer data by a store-carry-and-forward paradigm when network is interrupted. However, these routings do not consider the Quality of Service...
Software-Defined Networking (SDN) Architecture is relatively well defined, but the standards still need further development. Currently, working groups are developing Application Programming Interfaces (APIs) in which network monitoring is a priority, because it is the first step towards controlling a network. We present a network monitor that provides basic Quality of Service (QoS) parameters without...
In this paper we analyzed suitability of different routing algorithms for establishing bandwidth-delay constrained traffic tunnels in SDN backbone networks. Bandwidth rejection ratio was used as indicator of algorithm's ability to efficiently utilize network resources. Through set of simulations on two real backbone topologies we showed that network topology can affect algorithm's performance, and...
We present the framework for a heterogeneous internetworking service architecture to provide probabilistic quality of service guarantees to short critical messages prior to transmission. The TCP/IP Internet is not suited to bear mission-critical data across administrative domain boundaries with stringent delivery requirements because Border Gateway Protocol obscures network state information. Critical...
Mobile networks in the military tactical domain, include a range of radio networks with very diverse characteristics and which may be employed differently from operation to operation. When interconnecting networks with dissimilar characteristics (e.g. capacity, range, mobility) a difficult trade-off is to fully utilize the diverse network characteristics while minimizing the cost. To support the ever...
