Disaster scenarios with multiple Mobile Ad hoc Networks formed by the communication equipment of first responders are one example for such networks. In this paper, we evaluate different delay tolerant routing schemes based on realistic mobility models and traffic patterns. Both options are crucial as the routing schemes usually exploit the movement of the nodes in order to deliver the messages. Our results show that the choice of a routing protocol has an impact on the experienced delay, but a DTN-based communication system should also provide the necessary contact opportunities. Therefore, we present a solution to integrate additional nodes and efficient routing to address this.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122481394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Invisibility is a new term for ISC to adopt a communication process between light emitting device, for instance, display and image sensor (e. g: smartphone camera) without notifying the users of the data that is embedded in the image of the display. Although several method has been suggested for invisible communication between display and camera, this work proposes a new mechanism to transmit data from the display image to image sensor receiver. The intensity of the pixels in an image is varied over a period sequentially that the changes can be converted to a signal for communication. The derived signal from the sequential changing of the pixels can be compared to the RF signal in case of communication aspect. In addition, the idea of MIMO has been applied in the communication with a view to removing the shortcomings of low data rate issues of the ISC technology. The performance analysis of our proposed scheme illustrates the practicability with the advantages of the communication methodology.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127582879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The operation of most network protocols in ad hoc networks depends on broadcasting control information among nodes. In traditional ad hoc networks, due to uniform channel availability, broadcasting is easily implemented as all nodes can be tuned to a single common channel. However, broadcast in cognitive radio ad hoc networks is a much more challenging task. The complexity emerges from the fact that harmful interference with the transmissions of primary users (PUs) must be avoided. In this paper, we propose a fully-distributed broadcast protocol for cognitive radio ad hoc networks that alleviates the interference collision risk to the PU communications, explicitly protect primary receivers that are not detected during spectrum sensing and provides a high successful broadcast ratio. Furthermore, we consider practical scenarios in our design where no global network topology is known or no common control channel is assumed to exist. A key novelty of this work is the formulation of the broadcast issue from the viewpoint of protecting PU-receivers, which is a distinctive feature in CR networks.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133730388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current traffic monitoring techniques collecting statistics from existing flow entries do not provide the flexibility of querying path-specific flow statistics at any aggregation levels. In this paper, we proposes PathMon which encodes flow and path information as tags to provide that flexibility and corresponding link-to-link correlations for further anomaly detection or traffic engineering tasks. Our implementation runs on commodity switches which are compliant to OpenFlow 1.3 specification and requires only a few monitoring entries for each switch along monitored paths and un-tag entries for each edge switch.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133885250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hybrid network topology compounded with highly dynamic nature of AANET leads to variable connectivity in the network. The connectivity in the network for direct air-to-air communication between aircrafts is primarily a function of velocity of air vehicles, position of air vehicles, direction of flight, range of communication and congestion. In this paper, we present a connectivity prediction model for the AANET. The proposed model does a space time analysis of connectivity in the regions of AANET. The model can identify areas of low connectivity in a region by grading connectivity in the AANET. The connectivity prediction complements the change in state of an aircraft as it joins the AANET in a cluster or mesh. The model directs idle or migrating members of the network to the higher regions of connectivity. Connectivity gradation reduces network setup time in the events of network disruptions, strengthening the network's self-healing capability. FCM clustering is used for translating 3D topology of the network in conjunction with network traffic to multiple domains, that represent an aircraft.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114190570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
