Nowadays in wireless network the energy consumption and sensor node energy renewable is major challenge. Which make sensor network weak and more critical. The problem of node reachability is considered and Amended Ant colony optimization technique is proposed for optimization. The proposed technique is used for the search of estimated solutions to distinct and endless optimization problems and for...
With the increasing complexity of networks, Software Defined Networks (SDNs) have been developed to help administrators configure and operate network services with controllers such as Beacon, OpenDaylight and Floodlight. These controllers provide a suitable platform for high bandwidth applications. In this paper, several SDN controllers are evaluated using different network topologies. Some controllers...
Vehicular Ad-Hoc NETworks (VANETs) have received considerable attention in recent years, due to its unique characteristics, which are different from Mobile Ad-Hoc NETworks (MANETs), such as rapid topology change, frequent link failure, and high vehicle mobility. The main drawback of VANETs network is the network instability, which yields to reduce the network efficiency. This paper proposes a novel...
In Many/Multi-core processor architectures, hundreds and thousands of Intellectual Property (IP) cores are integrated to reinforce parallel processing and high performance computing. Integration of IP cores is effectively realized by a scalable communication framework, Network on Chip (NoC). NoC comprises of routers and interconnection links which aid transfer of information between IP cores. It is...
In this paper, we investigate malicious detection and avoidance of black hole attack for smart meter network. In terms of routing protocol, the reactive routing protocol Ad hoc On-Demand Distance Vector (AODV) is commonly adopted for smart meter network and is considered in our paper. However, the default AODV is vulnerable to black hole attacks. To detect and avoid black hole attacks, we propose...
A cognitive vehicle network is date from Vehicular Ad hoc Networks (VANET), which is proposed to solve the problem of control channel and spectrum scarcity in VANET. To resolve channel conflict problem in channel switching in vehicle network, a new dynamic spectrum allocation algorithm (DSAARCC) is proposed. When the vehicle user chooses the channel, to minimize the average delay under the condition...
In this paper the performance analysis of a routing algorithm for MANETs called Service Zone Gateway Prediction (SZGP) is presented. This is a non-cooperative and hybrid type of routing with a hierarchical multilayered structure, incorporating pre-computed multipath hop-by-hop distributed connectivity. The goal is balance of the load among the nodes and reliable and energy efficient communication...
Network on chip (Noc) is a neoteric technique, which is used to interconnect the nodes present in between the system on chip (Soc). In network on chip, routing is the important process to select the more appropriate and better path among the available path. In normal routing technique, the throughput and performance is moderate in order to get one output packet. To improve the throughput and performance...
It will cause the loss of information in the distributed satellite networks, if the network node is failure. For this problem, a method for distributed satellite networks based on standby nodes is presented in this paper. Firstly, it can establish a main path and confirm main nodes according to max-throughput principle in this method. Secondly, it can establish standby nodes set for the main path...
A structured overlay running as the base of a DHT or ALM occasionally receives a large number of messages collectively. Those cases are opportunities for an overlay to bundle multiple different messages into a single message and achieve extraordinarily effective message deliveries. Such message bundling reduces the number packet transmissions on an underlay network such as an IP network. This paper...
The Vehicular Ad Hoc Networks (VANETs), as an important part of intelligent transportation systems (ITS), has been becoming a promising research area. Due to the high mobility of vehicles and intermittent connected topology resulting in the dramatically changing network topology, it is difficult to design a protocol including congestion control mechanism, which is helpful for a well network performance...
In order to verify the application effect of MANET Routing Protocol in vehicular ad hoc network, the table driven routing priors DSDV, OLSR and on-demand routing reactive AODV are used to verify the results. In this paper, the simulation platform is built by NS3 and SUMO, and the performance of MANET is verified by comparing the network performance parameters, such as throughput, packet delivery rate...
Energy efficient routing and increasing throughput is a challenging task in fully connected wireless ad hoc networks.

The MAC modification is carried out with the help of the channel state metric. AOMDV routing strategy...
Multi-path allocation has been proposed as a simple way to achieve traffic protection in different networking domains. In this work dual-path allocation is proposed for Elastic Optical Networks (EON) assuming dynamic offered traffic, and its performance is quantified by simulation. Indeed, dual-path allocation is compared with partial dedicated path protection assuming different scenarios. In addition...

In vehicular ad hoc networks (VANETs), due to highly mobile and frequently changing topology, available resources and transmission opportunities are restricted. Transmitting frames efficiently within transmission opportunities is very important for system performance. Generally, there are many transmissions between many senders and receivers in a congested environment, which leads to network congestion...
We study the capacity scaling law of a device-to-device (D2D) caching network where n nodes are placed on a regular grid of area n. Each node caches some (coded) bits from a content library and requests a file from the library independently according to the Zipf popularity distribution. We propose a cache-induced hierarchical cooperation scheme which achieves the optimal capacity scaling law under...
