A prime source of collisions in underwater acoustic communication networks (UWANs) is the so called near-far effect, where a node located farther from the receiver is jammed by a closer node. While common practice considers such situation as a challenge, in this paper we consider it as a resource, and use it to increase network throughput of spatial reuse time-division multiple access. We propose...
The aim of topology-transparent scheduling algorithms for multi-hop wireless networks is to find a schedule for the nodes that does not need re-computation when the network topology changes. It caters to highly dynamic scenarios where topology changes occur faster than the speed at which schedule updates can be orchestrated. These algorithms normally take as input only global network parameters like...
This work describes a cross-layer resilient protocol stack for survivable network communications during regional challenges. The GeoDivRP routing protocol collects network statistics and calculates multiple geodiverse paths; it provides these geodiverse paths upstack to the resilient transport protocol, ResTP, for resilient multipath communications. ResTP provides multiple resilience modes to cope...
This paper presents a controlling approach to improve throughput using cross layer integration. Now a days communication networks require minimal interference and maximum accuracy with a faster data rate. Throughput improvement has become a vital issue in deploying broadband wireless sensor networks. Based on integration of optimum power allocation and memory blockage a novel approach of cross layer...
A network-on-chip (NoC), having guaranteed-throughput (GT) or guaranteed bandwidth service by using a flexible method to establish a connection-oriented data communication at runtime, is presented in this paper. The GT packets can share communication link with a flexible manner, where flits belonging to the same packet will have the same local identity-tag (ID-tag). The ID-tags of each packet will...
The wireless sensor network (WSN) consist of wireless sensor nodes, which are deployed randomly in a surge of unforeseen applications. Topology Control (TC) is the most essential approach used for minimizing energy consumption that extends the in WSN time. Also increases the throughput of the topology and minimize the radio interference. The aim of the proposed context aware topology control is to...
VANET is a part of MANET which is specific on communication between vehicle to vehicle or between vehicles to its surrounding environment infrastructure. One of the most widely used routing protocol at VANET implementation are AODV (Ad-hoc On-Demand Distance Vector) and DSDV (Destination Sequence Distance Vector Routing), which are topology based routing protocol. VANET dynamic network architecture...
Content Centric Networking(CCN) is using similar principle such as that of ICN, CDN, NDN which are the next generation of the Internet. Forwarding control is one of the important mechanism for the performance in content centric networking. When there is congestion in the network, the consumer have to adapt the alternative path in order to download the Data packet. If the consumer keeps the current...
It is expected that large number of IoT devices and IoT network will be connected to the Internet. In these environments, congestion of network links could be rapidly increased due to the bust IoT traffic especially related with video devices. To avoid the congestion, currently, End-devices control the congestion links by using congestion control scheme on TCP stack such as Tahoe, Reno, NewReno, and...
With the rising popularity of WirelessCommunication, Mobile Ad hoc Network (MANET) hasobtained its own place to be analyzed. The potentialapplications of MANET are growing tremendously due to itsrapid changing technology. Wireless network can beestablished in two modes. One is "Ad hoc mode" where thenodes are self-organized and another is "Infrastructuredmode" where the nodes are...
Network-on-Chip (NoC) is the communication backbone of multi-core and many-core processor architectures. Wormhole flow control is the commonly used flow control mechanism in on-chip interconnection networks, however it causes head-of-line blocking as network load increases which can be solved using virtual channel flow control. In this paper we investigate the effect of Virtual Channels (VC) on the...

The authors consider MPTCP offerings such as multipath aggregation, increased throughput, enhanced resilience, network handover and employing various congestion control algorithms over multipaths to aggregate available bandwidth as key factors to assess experiments with various topologies.
In this paper, a Three-Dimensional (3D) flexible routing algorithm is proposed for generic 3D Network-on-Chip (NoC). The proposed approach, Direct-Elevator, is based on the Elevator-First Algorithm which is independent of the network topology, number of interconnects and placement of interconnects. Direct-Elevator is tailored for 3D-NoC structures, offering a lower communication latency than its predecessor...
In this study we explore the gain that can be achieved by jointly allocating flow on multiple paths and employing successive interference cancelation (SIC), for random access wireless mesh networks with multi-packet reception capabilities. More precisely, we explore a distributed flow allocation scheme aimed at maximizing average aggregate flow throughput, while also providing bounded delay, when...

the network topology of interconnection networks plays a fundamental role in the performance of computer architecture. The most commonly used network topologies are Mesh, Torus and their extended versions.

Distributed desynchronization approaches lead to time-division multiple access (TDMA) of the shared medium without requiring a central coordinator. All such methods are based on the principle of reactive listening of periodic fire messages. The advantage of distributed desynchronization (DESYNC-TDMA) is the fact that it comprises a decentralized approach of very low complexity. It is therefore of...
The new standard for narrowband PLC-based communications IEEE P1901.2 defines two mechanisms which do not exist in the majority of its wireless counterparts — dynamic frequency mapping (tone mapping), and existence of several modulations. Until now, the benefit of these mechanisms was not taken explicitly into account by the routing protocols. In this paper, we propose a novel metric for RPL — the...
