Time travel to the UK in 2025: Harry is a teenager with a smartphone and Pauline is a senior citizen with Alzheimer\u2019s who relies on smart glasses for independent living. Harry is frustrated his favourite online game is slow, and Pauline is anxious since her healthcare app is unresponsive.<\/p>\n\n\n\n
Forbes predicts<\/a> that by 2025 more than 80 billion devices, from wearables<\/a> and smartphones, to factory and smart-city sensors, will be connected to the internet. Something like 180 trillion gigabytes of data will be generated that year.<\/p>\n\n\n\n Currently almost all data we generate is sent to and processed in distant clouds. The cloud is a facility that provides virtually unlimited computer power and storage space over the internet. This mechanism is already becoming impractical, but by the time billions more devices are connected, delays due to congested networks will be significant. Harry and Pauline\u2019s frustrations will be the norm as apps communicate with distant clouds over a busy internet, becoming slower and less responsive.<\/p>\n\n\n\n Disruptive technology<\/strong><\/p>\n\n\n\n After all, seconds matter. Harry will have a poor gaming experience if there is a 50 millisecond delay on his smartphone. Even a 10 millisecond lag between the movement of Pauline\u2019s head and the appearance of processed information on the smart glasses will cause motion sickness.<\/p>\n\n\n\n To continue reading, please click here<\/a>.<\/p>\n\n\n\n <\/p>\n\n\n\n Article originally appeared in The Conversation.<\/a><\/p>\n\n\n\n The featured image<\/a> has been used courtesy of a Creative Commons license. <\/a><\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Dr Blesson Varghese looks at the role of “edge computing” in helping to reduce delays in processing data normally handled by the cloud. <\/p>\n","protected":false},"author":2540,"featured_media":5197,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[444],"tags":[],"class_list":["post-5191","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-information-technology"],"mb":[],"acf":{"authors":{"simple_value_formatted":"","value_formatted":null,"value":null,"field":{"ID":9774,"key":"field_66d0cbf58f930","label":"Authors","name":"authors","aria-label":"","prefix":"acf","type":"relationship","value":null,"menu_order":1,"instructions":"","required":0,"id":"","class":"","conditional_logic":0,"parent":9772,"wrapper":{"width":"","class":"","id":""},"post_type":["authors"],"post_status":["publish"],"taxonomy":"","filters":["search"],"return_format":"id","min":0,"max":10,"allow_in_bindings":0,"elements":["featured_image"],"bidirectional":0,"bidirectional_target":[],"_name":"authors","_valid":1}},"description":{"simple_value_formatted":"","value_formatted":"","value":"","field":{"ID":9776,"key":"field_66d2183027749","label":"Description","name":"description","aria-label":"","prefix":"acf","type":"wysiwyg","value":null,"menu_order":3,"instructions":"","required":0,"id":"","class":"","conditional_logic":0,"parent":9772,"wrapper":{"width":"","class":"","id":""},"default_value":"","allow_in_bindings":0,"tabs":"all","toolbar":"basic","media_upload":0,"delay":1,"_name":"description","_valid":1}}},"jetpack_featured_media_url":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-content\/uploads\/sites\/76\/2018\/12\/Clouds.jpg","jetpack_sharing_enabled":true,"amp_enabled":true,"mfb_rest_fields":["title","jetpack_featured_media_url","jetpack_sharing_enabled","amp_enabled"],"_links":{"self":[{"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/posts\/5191","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/users\/2540"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/comments?post=5191"}],"version-history":[{"count":0,"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/posts\/5191\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/media\/5197"}],"wp:attachment":[{"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/media?parent=5191"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/categories?post=5191"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.qub.ac.uk\/qpol\/wp-json\/wp\/v2\/tags?post=5191"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
