There isno way to prevent the natural disaster, but its impacts can be reduced or rescued.Adequate prior disaster information can save a significant number of lives andproperties. Therefore, the accurate alerts or notifications about disasters are neededfor Myanmar people. Now, there are many mobile phone users along with thetechnological progress around the world including in Myanmar. Thus, mobile devicesbecome the most convenient communication tools which have not time and placelimitations. A suitable disaster notification system based on mobile phones is one ofthe useful things as it is also a requirement of Myanmar people. Because of the fastand easy way, notification messages via mobile phones take benefits in thecommunication activities.The main service task of this system is the delivery of possibly disasterinformation to mobile devices which are in the imminent disaster region. The systemfinds whether mobile is within a predefined area using its current location. The userswho are in the imminent disaster area will receive the required notification messages.In this system, the server gets the current mobile position and keeps their locationupdate structurally are a great challenge along with the continuously changing in theposition of mobile devices. Therefore, a suitable technique is needed to store andupdate mobile positions. Moreover, when a message delivery to mobile deviceswithin the specified range, the factor to be considered which mobile should be sentthe message first. One of the most suitable solutions is sending the nearest mobilelocations as fast as possible.In this system, a two-dimensional balanced structure, a presort-nearestlocation index tree is proposed that allows maintaining, updating, and circular rangequerying mobile objects within the required time. It also supports generating nearestlocations by index structure from the desired query point. In this structure, all of thelocation nodes are placed by level order thus nodes at any distance can easily findwithout traversing the whole tree and the searching time may reduce greatly. It isharmonized to solve nearest neighbor location queries since the locations of the datapoints are based only on their relative distances from each other. In addition, allmobile locations in the range will be available by the distance at one time.Then, the system architecture is built for sending notifications by connectingwith firebase cloud messaging (FCM), application server and mobile devices in theimminent disaster area. To overcome being unnecessary updates at the server, HybridUpdate Algorithm is proposed in this system. In this case, a virtual mobile dataset isneeded to access several of moving mobile locations for performance evaluation.Thus, a synthetic mobile location generator is proposed that is based on the creationof two-dimensional mobile locations. As a result, this generator is free from locationprivacy and confidentiality.The necessary performances are tested by using a JUnit testing schema, whichcan automatically apply to run in testing functions. For performance evaluations, theexecution time, updating time and CPU usage are measured by comparing betweenproposed presort-nearest location index tree, presort range tree and KD tree accordingto the evaluation of tree construction, range searching and neighbor searching overmoving objects. Besides, the distance-based method is applied for comparison of twoof index structures."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value":[]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2019-09-23"}],"displaytype":"preview","filename":"ThuThuZanThesisBook.pdf","filesize":[{"value":"1658 Kb"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://meral.edu.mm/record/4315/files/ThuThuZanThesisBook.pdf"},"version_id":"53c73032-06f8-4271-abe0-d1d2ba8ddc4e"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_issue":"","subitem_journal_title":"","subitem_pages":"","subitem_volume":""}]},"item_1583103147082":{"attribute_name":"Conference papers","attribute_value_mlt":[{"subitem_acronym":"","subitem_c_date":"","subitem_conference_title":"","subitem_part":"","subitem_place":"","subitem_session":"","subitem_website":""}]},"item_1583103211336":{"attribute_name":"Books/reports/chapters","attribute_value_mlt":[{"subitem_book_title":"","subitem_isbn":"","subitem_pages":"","subitem_place":"","subitem_publisher":""}]},"item_1583103233624":{"attribute_name":"Thesis/dissertations","attribute_value_mlt":[{"subitem_awarding_university":"University of Computer Studies, Yangon","subitem_supervisor(s)":[{"subitem_supervisor":""}]}]},"item_1583105942107":{"attribute_name":"Authors","attribute_value_mlt":[{"subitem_authors":[{"subitem_authors_fullname":"Zan, Thu Thu"}]}]},"item_1583108359239":{"attribute_name":"Upload type","attribute_value_mlt":[{"interim":"Publication"}]},"item_1583108428133":{"attribute_name":"Publication type","attribute_value_mlt":[{"interim":"Thesis"}]},"item_1583159729339":{"attribute_name":"Publication date","attribute_value":"2019-01"},"item_1583159847033":{"attribute_name":"Identifier","attribute_value":"http://onlineresource.ucsy.edu.mm/handle/123456789/2254"},"item_title":"Mobile Location Based Indexing of Disaster Notification System","item_type_id":"21","owner":"1","path":["1597824322519"],"publish_date":"2019-09-23","publish_status":"0","recid":"4315","relation_version_is_last":true,"title":["Mobile Location Based Indexing of Disaster Notification System"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2021-12-13T00:54:21.675882+00:00"}
