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...
Location-disclosure is a major privacy issue in vehicular social networks when people are interested in traffic-related cooperation drive, location-aware services, and other applications. In this paper, we propose a Social-aware Location-privacy Protection (SLP) method in vehicular social networks to protect location privacy. This method enables trustworthy users to obfuscate an original sender's...
Nowadays Mobile Ad Hoc Networks has become a popular research subject due to its characteristics. Generally Mobile Ad Hoc Networks have given the low physical security for mobile devices. With this problem there are many chances that the intruders may attack the nodes over the function. Using Intrusion Detection Techniques we can find the intruders before it may attack the nodes. Intrusion Detection...
Opportunistic Mobile Social Networks (MSNs) are a type of delay-tolerant networks that are composed of mobile nodes with social characteristics. Most of current research on forwarding algorithms for MSNs leverages the properties of social networks, such as community and centrality. However, the fundamental property, interaction, has not received sufficient attention. The effects of interactions consist...
Mobile ad-hoc network is networks that are collection of mobile device that can communicate and share information between each other, without any predefine infrastructure or centralized system. Another challenge in MANET is energy constraints because each of the mobile nodes is operated by limited energy battery. This paper presents a new on-demand power saving routing algorithm for mobile ad-hoc...
This paper addresses the problem of joint routing and backhaul link scheduling in a dense small cell network using 60GHz multi-hop backhaul, coordinated by a local Cloud-RAN central unit. Our objective is to optimally select the backhaul links and paths to be activated in time domain to enhance the cell throughput and to minimize the total delay, considering the backhaul channel conditions and the...
In this paper, we present the Context-Aware Opportunistic Resource-Based Routing Protocol (CORB) for intermittently-connected stationary wireless sensor networks. This protocol targets domains such as ambiance control in smart buildings. Unlike existing context-aware routing approaches which consider node mobility as the main source of disconnection, CORB only considers the nodes' limited resources...
The dynamicity of modern communication networks relays on the switching and routing infrastructure. The Cloud, the Internet of Things, the Big Data, the mobile data communications, the 4k video all demand an even more dynamic network provided by high performance switching and routing infrastructure.
In the era of the Internet of Everything, users with handheld or wearable devices equipped with sensing capability have become producers as well as consumers of information and services. The more powerful these devices get, the more likely it is that they will generate and share content locally, through ad hoc opportunistic connectivity, leading to the presence of distributed information sources and...
In this paper, we first present a heterogeneous theoretical framework for DTNs where the contact between nodes is based on independent differently distributed assumption. Moreover, the message forwarding process follows a Gamma Distribution. Then, we propose a new spray routing scheme based on this framework. Moreover, we compare our routing protocol with traditional spray routing (TSR) protocols...
Information-centric networks have recently been drawing increasing attention in academia as well as in industry. Information and content retrieval is a critical service for mobile ad-hoc networks. It relies on other resources and tools, such as internal storage, content searching and sharing, delay-tolerant delivery, etc. Previous studies have shown that social networking can assist delay-tolerant...
Current ICN research favors a key-value-store view of the network, where location agnostic names typically resolve to documents, data blocks or sensor values. We believe that names should not only refer to data but also to functions and computation tasks. In Named Function Networking (NFN) the network's role becomes to resolve names to computations, par example by reducing λ-expressions. In doing...
This paper presents mPASS (mobile Pervasive Accessibility Social Sensing), a system designed to collect data about urban and architectural accessibility and to provide users with personalized paths, computed on the basis of their preferences and needs. The system combines data obtained by sensing, crowdsourcing and mashing-up with main geo-referenced social systems, with the aim of offering services...
Opportunistic Mobile Networks (OMNs) are characterized by intermittent connectivity among the nodes, which results in lack of end-to-end communication paths. The nodes depend upon the other nodes for forwarding their messages and, therefore, the intermediate nodes play the crucial role of cooperation in forwarding the messages of the others nodes. Many existing mechanisms - for example, incentive-...
This paper proposes VideoFountain, a novel service that deploys kiosks at popular venues to store and transmit digital media to users' personal devices using Wi-Fi access points, which may not have Internet connectivity. We leverage mobile users to deliver content to these kiosks. A key component in this design is an in-depth understanding of user mobility. We gather real mobility traces from two...
An emergency response networking scenario is considered, in which immediately after the strike of a disaster, mobile terminals autonomously form an ad-hoc network. Distress nodes, use this network to disseminate help-requests as a far outcry mechanism. In turn, and upon their arrival, emergency response units opt to gain access to the withstanding ad-hoc network in order to retrieve those disseminated...
Information-centric networks (ICNs) have emerged as a prominent future Internet architecture. They work on the principle that, in today???s society, a network should be optimised towards the delivery of information, rather than the transit of messages between pre-determined end hosts. At the same time, another prominent research direction has been the delay-tolerant networking initiative, which argues...
We evaluate an algorithm that efficiently computes short paths in social networks by exploiting their spatial component. The main idea is very simple and builds upon Milgram's seminal social experiment, where target individuals were found by having participants forward, or route, messages towards the target. Motivated by the somewhat surprising success of this experiment, Klein berg introduced a model...
In tactical environment, MANET (Mobile Ad Hoc Network) has the network characteristics which make highly dynamic nodes, self-organized in fully-distributed style. Also, it has a harsh wireless channel environment compared to the commercial networks. In these channel environments, optimal path decision suited for Quality of Service (QoS) of transmitted tactical traffics must be performed by recognizing...
The growth of wireless devices with short-range communications capabilities is making research into Pocket Switched Networks (PSN)s more appealing. While some recent research has investigated the role of location in predicting the mobility patterns of autonomous agents within PSNs, little attention has been paid to the location as a resource itself. In this paper we investigate the potential for stationary...
