In this paper the applicability of a fault tolerance synchronization algorithm is presented through data packet headers. Packet headers provide indicts for networking equipment on what must be done and in the case of real-time persistent routed sessions, these are a concise guideline on how to tune each parameter. Real-time sessions are transmitted with connection oriented protocols and need a constant...
Recently, applications' demands for the network become more multifaceted. Highly functional application-to- application communication services such as bandwidth aggregation, fault tolerant communication, and delay/disruption tolerant networking (DTN) were developed independently in the network layer, the transport layer, and the application layer. As a result, protocol layering has become complicated...
Kademlia is a decentralized overlay network, up to now mainly used for highly scalable file sharing applications. Due to its distributed nature, it is free from single points of failure. Communication can happen over redundant network paths, which makes information distribution with Kademlia resilient against failing nodes and attacks. In this paper, we simulate Kademlia networks with varying parameters...
In this paper for the first time the mathematical model and the two-level method of fault-tolerant inter-domain routing in telecommunications networks was presented. The novelty of the model is its decomposed representation and formulation the inter-area interworking conditions. The implementation of these conditions guaranteed the connectivity of calculated inter-area paths. The research of the proposed...
In this paper the networked routers decision support tables are presented as big data structures. Routing tables ease the modeling of interconnected networks traffic and update costs, and have grown in size presenting a multitude of possibilities for communication infrastructures. The created complexity has reached a volume of processing that tends to be efficiently administered with new protocols...
The default gateway protection scheme in fault-tolerant IP routing is proposed in the given paper. In solving the technological problem of the fault-tolerant IP routing, it is necessary to solve either mixed integer nonlinear programming problem during minimization of the object function, or nonlinear programming problem with limitations defined. The proposed model also provides the support of load...
Fault tolerance is one of the critical issues in Wireless Sensor Network (WSN) applications. The problem of missing sensor node, communication link and data are inevitable in wireless sensor networks. WSNs experience failure problems due to various factors such as power depletion, environmental impact, radio interference, asymmetric communication links, dislocation of sensor node and collision. Many...
The reliable transmission of information is an inherently difficult and unpredictable task for LEACH-based networks. This is due to their adoption of centralized data exchange points which are expected to deliver data transmission reliability without being compromised by increasingly high rates of energy consumption. Given that this is a goal made more difficult by the constraints intrinsic to WSNs,...
As the wireless sensor network has made its steps in mobility based applications like health monitoring, wildlife monitoring, search and rescue, it is desirable to have a reliable routing protocol to deal with the routing issues of mobile sensor nodes and battery is also the main constraint for sensor nodes so routing protocol should be energy efficient. Existing approaches for routing in Cluster...
The design of reliable MPSoCs is mandatory to cope with faults during fabrication or product lifetime. For instance, permanent faults on the interconnect network can stall or crash applications even though the network has alternative fault-free paths to a given destination. This paper presents a novel fault-tolerant communication protocol that takes advantage of the NoC parallelism to provide alternative...
Mechanisms for fault-tolerance in MPSoCs are mandatory to cope with faults during fabrication or product lifetime. For instance, permanent faults on the interconnect network can stall or crash applications even though the network has alternative fault-free paths to a given destination. This PhD work presents a fault-tolerant communication protocol that takes advantage of the NoC routing method to...
Internet of Things (IOT) is a wireless ad-hoc network of everyday objects collaborating and cooperating with one other in order to accomplish some shared objectives. The envisioned high degrees of association of humans with IOT nodes require equally high degrees of reliability of the network. In order to render this reliability to IOT networks, it is necessary to make them tolerant to faults. In this...
In pervasive environment various devices with varying medium of access, mobility and connectivity have different types of services available among themselves. We are in need of a computing scheme which can utilize this limited amount of resources in the network in an efficient way. In this paper, we have considered various aspects of routing to find out the most efficient devices for service provisioning...
Recently many Wireless Sensor Network (WSN)-based agriculture monitoring systems have been implemented mostly for developed countries. WSN in these monitoring systems uses tree topology and multi-hop dynamic flooding routing protocol that are not energy efficient and has a single point of failure. Though some protocols use zone-based routing they consider that a large number of sensors are deployed...
WSNs are inherently power constrained and are often deployed in harsh environments. As such, node death is a possibility that must be considered while designing protocols for such networks. Rerouting of data is generally necessary so that data from the descendant nodes of the dead node can reach the sink. Since slot allocation in TDMA MAC protocols is generally done based on the routing tree, all...
Recent studies on service discovery protocols in vehicular networks have shown promising results. However, very little work has been reported on how to integrate the fault tolerance feature into these mechanisms. This feature is vital for the success of the deployment of service discovery protocols in vehicular networks. Drivers on their cars should not have their requests dissatisfied or their connections...
Delay Tolerant Mobile Sensor Network (DTMSN) is the network for pervasive information gathering. Traditional data information gathering approaches may not fit for DTMSN for its intermittent connectivity. This paper proposes an Activity Based Data gathering protocol (ABD). In DTMSN, activity of different sensors may vary since they are attached to different entities, the message replicated by the active...
Wireless Sensor Networks (WSNs) are highly distributed networks consisting of a large number of tiny, low-cost, light-weight wireless nodes deployed to monitor an environment or a system. Each node in a WSN consists of three subsystems: the sensor subsystem which senses the environment, the processing subsystem which performs local computations on the sensed data, and the communication subsystem which...
With the recent focus on cloud computing a new type of system topology came up: clusters in geographically distributed datacenters that are connected by high-latency networks. Current structured overlay networks (SONs) are not well prepared for such environments with heterogeneous network performance and correlated node failures. We show how the beneficial features of SONs, namely self-management,...
Service discovery is crucial in the development of fully decentralized computational grids. Among the significant amount of work produced by the convergence of peer- to-peer (P2P) systems and grids, a new kind of overlay networks, based on prefix trees (a.k.a., tries), has emerged. In particular, the Distributed Lexicographic Placement Table (DLPT) approach is a decentralized and dynamic service discovery...
