In this context, aerial networks may play an important role by widening the concept of access networks. This paper describes and analyzes one of the most promising applications of Unmanned Aerial Vehicles, commonly known as drones, in the field of communications: Extending the capacity or coverage of wireless systems through the deployment of aerial communication networks. We present a comprehensive characterization study of an experimental system to deploy an aerial WiFi network. To do so, an Intel Galileo development board is appropriately configured and equipped as a WiFi node playing either the role of an access point in the infrastructure mode or of an intermediate hop in the ad-hoc operational mode. This device is then integrated onboard a drone. We compare both WiFi modes in terms of coverage area, throughput, and energy efficiency. Preliminary results reveal that there is a trade-off between coverage and data rates, for which the infrastructure mode performs better, and energy efficiency, where the ad-hoc mode is more responsive.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125347598","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}

Sendai Framework1 of Action calls for risk reduction by implementing early warning systems [2]. A prevailing challenge is for authorities to coordinate warnings across disparate communication systems and autonomous organizations [3]. Cross-Agency Situational-Awareness platforms and the ITU-T X.1303 Common Alerting Protocol (CAP)2 interoperable data standards presents themselves as solution for diluting the inter-agency rivalries and interconnection disparities [4]. The Sahana Alerting and Messaging Broker (SAMBRO) was designed to overcome these issues by providing a Common Operating Picture and a platform for all Stakeholders to share early warnings. To that end, the CAP-on-a-MAP project is implementing SAMBRO and the CAP standard along with the policies and procedures in the Maldives, Myanmar and Philippines. The project is applying an agile development methodology with a design, build, test, and redesign strategy for implementing the cross-agency situational-awareness and warning system in the respective countries. This paper discusses the country context implementation challenges and discusses strategies fostered through the introduction of the CAP content standard for warning system designers to consider for overcoming similar challenges.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129756188","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 existing Dynamic Adaptive Streaming over HTTP (DASH), though works well for stored video up to some extent, poses a complication in live transmission thereby depreciating the streaming quality due to high link bit rate fluctuation. In this paper, we have proposed an efficient ARIMA Based Bit Rate Adaptation (ABBA) model in the receiver/client side that estimate the link traffic based on the incoming packet bit rate to predict the subsequent future link capacity in order to notify the sender/server. Based on the response from the receiver the server adapt its outgoing stream as per forecasted link data rate, and hence eliminate the degradation of video due to channel throughput variations. The proposed ABBA algorithm was implemented on IP over 4G wireless network and the streaming quality was evaluated on several full reference metrics of video quality. The test result outperformed an existing buffer based approach and also a fuzzy based adaptation algorithm. For example, the ABBA algorithm exhibited an average increase of 22 % in PSNR and 9% in SSIM than a buffer based method.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127025895","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}

Small boat operators, which form 80% of entire fishing community, are more vulnerable to the wilder nature of the ocean, due to dynamic sea current, wind speed, direction and wave heights, etc. This is also one of reason for fishermen entering accidently in other country's territory, getting caught and sometimes costing their life. This poses a serious question to fishermen and their family, whether they would return the next time they venture out in to the sea. Deep sea mobile connectivity and Information, given in advance about the sea conditions such as wind speed and wave height can help fishermen to plan their trip effectively and avoid the danger zone. This infrastructure could provide path of building \"knowledge society\" to fishermen deprived of real time and usable information. For realizing this, integration of the existing communication technologies like VHF transceivers, satellite communication and extension of mobile communication network is needed. A consortium of partners like Central Marine Fisheries Research Institute, Tata Consultancy Service and Tata Tele Services piloted a project for mobile signal extension into the sea upto 30kms. This enabled an extended network accessibility, which led to create an Early Warning System over a digital highway of 30 by 120 KM, along the coast. This paper captures the experiences and recommendations derived from this pilot.","PeriodicalId":393816,"journal":{"name":"2016 ITU Kaleidoscope: ICTs for a Sustainable World (ITU WT)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130711645","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}
