Many applications of sensor networks collect massive data in a coordinated approach, such as monitoring volcanoes, oceans and forests. We propose, therefore, two protocols at the network stack to enable multiple frequency communication. MultiFCTP extends the state-of-the-art CTP to route packets using multiples frequencies. FlushMF is a transport protocol that extends Flush by supporting multiple...
Future small-cell networks using the millimeter-wave (mmW) band to provide backhauling or user access need for adequate and innovative simulation tools in order to optimize the pre-deployment design and thus reduce installation and post-deployment optimization costs. The proposed paper makes some recommendations on the inputs and simulation blocks required for the mmW small-cell design. A particular...
Despite of high throughput and low fabrication cost of vertically partially connected 3D NoCs, thermal difficulties arise from poor heat dissipation and inappropriate traffic distribution of these kinds of 3D NoCs. This paper proposes an adaptive routing algorithm in order to manage thermal challenges in partially connected 3D NoCs. In the proposed routing algorithm, vertical links declare their availability/unavailability...
The Wireless Network after Next (WNaN) radio is a multi-transceiver multi-frequency mobile ad-hoc network system that features four independent frequency agile transceivers and uses a variation of Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA). Utilizing WNaN's multiple transceivers, dynamic frequency assignment algorithm, and varying the hello packet interval can help alleviate the increased...
The paper considers multi-hop wireless mesh networks that serve multicast periodic packet traffic. The packets from each packet stream are generated at the stream's source node and traverse a number of wireless nodes in order to reach their multiple destination nodes. Packet periodicity means that a common repeatable frame of time slots is defined and that the packets to be transmitted arrive at the...
Early estimation of the peak power consumption of a system under development is crucial in assessing the design's reliability and thermal profile, and for benchmarking various architectural options and chip-level power management features. In this paper, we present a versatile power-virus generation technique for Networks-on-Chip (NoC), which allows the designer to quantify the realistically attainable...
A simple scheme to implement dedicated path protection in Elastic Optical Networks is proposed and evaluated under dynamic traffic conditions. It consists in splitting the spectrum available in the network links in two bands used respectively for working and backup traffic. These bands are conveniently sized taking into account the network topology and the routing constraints. When the band dedicated...
Science of networking is still a relatively immature area. Proposing an efficient dynamic routing protocol for MANET is an arduous and provoking task. Various protocols for routing phenomenon have been proposed to IETF [1]. Considering an ad-hoc network which is specified by frequently changing topology and infrastructure less connectivity, a protocol must be tested under realistic conditions but...
OpenFlow is currently the most commonly deployed Software Defined Network (SDN) technology. Some deployments designed with multi-controller OpenFlow have better scalability than standard OpenFlow. However, these deployments are not optimized for the Data Center Network (DCN), the cross-controller communication and routing may be inefficient. In this paper, we present the communication mechanism design...
MANET is one kind of non-infrastructure network which is composed of various mobile nodes. Due to the battery energy constraints in MANET, energy efficiency is an important factor while designing ad hoc wireless networks. Previous works tried to optimize the AODV protocol by proposing different schemes. In this paper, two solutions have been proposed to control the congestion problem of wireless ad-hoc...
In VANET network, vehicles are treated as nodes. Node position is determined by protocols, algorithms and applications. As its network changes rapidly, it is hard to route data among vehicle to vehicle and vehicle to infrastructure for a protocol. It is also hard to meet every traffic scenario by existing routing protocol. Routing protocol must adapt to rapid change of topology. Several efficient...
Due to high mobility of nodes, the major challenge of mobile ad hoc networks (MANETs) is the frequent link breakages which lead to numerous path failures and route discoveries. This paper introduces a novel signal strength based algorithm for RREQs forwarding (SAODV) to better exploit the neighbor coverage knowledge and hence reduce routing overhead in MANETs. The simulation results confirm the efficiency...

A wireless sensor network is modelled as a multi-agent system by concretely regards each sensoras an agent. Agents in the proposed approach are competitivewhere they need to cope with limited resources (i.e. availableenergy) in the network. Auction-based scheme (First-price...
Protecting communication from network failure is a major concern in current days. Here we have proposed an efficient algorithm which provides full protection over single link failure in a WDM optical fiber network with limited wavelength channels and reduces blocking probability by reducing backup wavelength channel requirement, thus it maximizes throughput. In this paper at first we have formulated...

This realizes effective data transmission considering disaster situation and its time variation. We have designed...
Extensive research is being done on Wireless sensor Networks (WSNs) in present decade. WSNs consist of large number of sensor nodes which perform sensing of certain phenomena and send the sensed data to the sinks. This operation consumes energy of sensor nodes which effects the lifetime of a network. To prolong the lifetime of WSNs various strategies and routing algorithms have been proposed. Use...
Network-on-Chip(NoC) has been well accepted for energy efficient on-chip communications for many-core systems. As the technology scaling drives the number of cores upward designers of the on-chip interconnect for many-cores chips are facing with the dilemma of meeting performance and energy requirements with power and thermal constraints. This paper focuses on the Network-On-Chip energy and performance...
In a multi-hop wireless network, a node can act as a candidate file provider to other nodes, if it has downloaded the file from the Internet. When another node requires the same file, all nodes which have already obtained the file can act as candidate file providers (sources) and transmit file together to the request node (destination). We form this as the multi-source transmission. As the multi-source...
