Although IEEE 802.11p technology is standardized for road safety and efficiency applications, the channel congestion problem is its key weakness necessitating distributed congestion control (DCC) algorithms on different layers of the communication stack. In this paper, we propose DCC-enabled Contention based Forwarding scheme targeting multi-hop dissemination of Decentralised Event Notification Messages...
Information-Centric Networking (ICN) introduces a paradigm shift from a host centric communication model for Future Internet architectures. It supports the retrieval of a particular content regardless of the physical location of the content. Emergency network in a disaster scenario or disruptive network presents a significant challenge to the ICN deployment. In this paper, we present a Content dIstribution...
The backpressure algorithm has been widely used as a distributed solution to the problem of joint rate control and routing in multi-hop data networks. By controlling a parameter V in the algorithm, the backpressure algorithm can achieve an arbitrarily small utility optimality gap. However, this in turn brings in a large queue length at each node and hence causes large network delay. This phenomenon...
In delay tolerant mobile sensor networks, the application may sometimes require informing all the sensor nodes in the network about the presence of a message while delivering it to a specific destination node. But, due to constraints on buffer space, it is not efficient to keep these message copies in the buffer of all nodes. In this paper, we propose a probabilistic approach for information dissemination...
The OpenFlow-based SDN is widely studied to better network performance through providing flexible routing paths. However, being designed to configure path hop-by-hop, it faces the scalability issue — both the flow table overhead and path setup delay are unacceptable for large-scale networks. In this paper, we propose PACO, a framework based on Source Routing (SR) to address that problem through quickly...
Delay Tolerant Network is a buzz word in Mobile Adhoc Network. Research in this direction started with the approach for interplanetary communication. Delay Tolerant Network (in short) DTN is an evolving research area. A way to store, carry and forward messages over the underlying existing infrastructure. The intermittent connectivity and limited resources of a DTN node make the routing difficult to...
Delay Tolerant Network (DTN) is primarily and specifically a class of MANET that is challenged. The working principle of DTN illustrates the mechanism to store information and carry it till some capable node is found and then a message is forwarded. This kind of implementation has found application areas like sparse and constrained networks. This paper explains the design specification issues of DTN...
In this paper, we address the problem of routing disruption attacks in Cognitive Radio Networks (CRNs). In routing disruption attacks, the malicious node intentionally drop data packets to consume more network resources or degrade routing performance. We propose a trust management model to mitigate such attacks in CRNs. Through monitoring forwarding behaviors of secondary users (SUs), trusts of SUs...
Delay-tolerant Network (DTN) is a computer network architecture that operates effectively over an extreme distance and communicates with heterogeneous networks that may affect the continuous network connectivity. DTN is particularly useful for the areas in which there are no direct connection (either physical or wireless) between source and destination over a long distance, as it can overcome the...
This paper presents a multicast Delay Tolerant Network (DTN) routing protocol that uses an economic gain based routing utility for device-to-device (D2D) commercial coupon dissemination. Majority of the existing DTN routing approaches are not practically applicable to commercial content dissemination since they attempt to individually optimize performance indices such as message delay, forwarding...
For making Mobile ad hoc network (MANET) more energy efficient swarm intelligence is used as a base and the clustered based approach as Bee-Ad Hoc-C which is an evolution from Bee-Ad-Hoc has been chosen as the best method in our previous work along with Stable Cluster Maintenance Scheme. In the proposed method parallel routing has been considered to improve the scalability of the system, reduce the...
In this paper, for secure routing optimization we are introducing dynamic trust management protocol in information centric network and delay tolerant network (DTN) environments. In the existing system, dynamic trust management for DTN is used to deal with the detection of the selfish, malicious misbehaving nodes and genuine loss nodes. To disrupt DTN operations, malicious nodes performing trust-related...
In distributed OpenFlow controller networks, the network flow is managed by set of associated rules that are maintained by switches in their local Ternary Content Addressable Memory (TCAM) and rules are made by concerned controllers, which are local to domains. However, TACM is expensive and consumes high power. The switch inside the forwarding plane has limited TCAM space and is infeasible to maintain...
Natural load-bearing structures, such as trees, have had to strive for survival in harsh environmental conditions. Over time, these structures have evolved, and are able now to optimize their shapes. Behind this optimization is a simple yet powerful rule called the axiom of uniform stress, which has successfully been applied to topology optimization in various engineering fields. Similar to physical...
For stabilizing power frequency in the grid, demand-supply balancing capability by manipulating the demand side, known as Demand Response (DR), is getting attention because of the continuous increase in renewable energy resources and deferrable loads such as electric vehicles in addition to the traditional adjustment function by supply side such as thermal plants. In the future smart grid, it is imperative...
A mobile adhoc network is an independent system of mobile stations associated by wireless link to form a system. This system can be modeled in the form of an uninformed graph. Adhoc networks are peer to peer, multihope networks were data packets are transmitted to a source to destination through intermediate nodes (which serve as router). The infrastructure is not the main issue to setup MANET and...
A fundamental problem in QoS (quality-of-service) routing is the multi-constrained path (MCP) problem. The MCP problem used the shortest path with respect to a single edge weighting function as an approximate solution to MCP. For solving MCP problem was offered a lot of methods. One of these methods is based on Lagrangian Relaxation. These algorithms allow finding the shortest paths from the source...
This paper is concerned with a crucial problem of MANET which is congestion control (CongClt). CongClt can be described as a mechanism used to control congestion (Cong) and keep the traffic below the capacity of the network. Many approaches have been proposed to overcome CongClt in Ethernet as well as in MANET. Controlling the Cong in MANET is quite difficult due to its fundamental characteristics...
WSN is a wide area communication, because of its wide variety of applications. The main limitations in WSN are its limited battery or energy, BW, memory and wireless communication capability. In traditional approach each sensor node is used to sense the surrounding environment and communicate with the sink node hence the battery consumption and bandwidth utilization is more. To overcome these two...
An interrelation between a topological design of network and efficient algorithm on it is important for communication or transportation systems. In this paper, we propose a design principle for a reliable routing in a store-carry-forward manner based on autonomously moving message-ferries on a special structure of fractal-like network, which consists of a self-similar tiling of equilateral triangles...
