Location-sensitive advertisements, ads targeted to a Wi-Fi user based in part on the physical location of that user, will be an important market in the near future. We have developed two schemes for distributing location-sensitive ads to Wi-Fi devices: BeaconStuffing and Neighborcast.<\/p>\n<p>BeaconStuffing fragments large messages, and embeds them in Wi-Fi beacons. This approach has three advantages:<\/p>\n<ul>\n<li>We do not require information from the client device to deliver ads to the client.<\/li>\n<li>We do not require the client to have Internet connectivity. In fact, we can deliver ads even when the client is connected to a different Wi-Fi network.<\/li>\n<li>We can supply dynamic information to consumers in real time. For example, a restaurant can continuously advertise an expected wait time to all wireless clients in its vicinity.<\/li>\n<\/ul>\n<p>In recent work, we developed a technique called Neighborcast, which enables group communication among physically nearby clients, even when the clients are on different frequency channels or connected to different Wi-Fi Access Points. We define two clients to be near if they can hear a common Wi-Fi Access Point, and construct an IP overlay spanning physically nearby clients. This technique enables retailers to send location-based advertisements\/annoucements to all physically nearby clients.<\/p>\n<p>Neighborcast is complimentary to BeaconStuffing. Neighborcast <b>does not<\/b> require modifications to the Access Points or the Wi-Fi drivers on the clients, and has a wider reach &#8212; content can be delivered to clients that do not even hear the retailer&#8217;s Access Point. However, compared to BeaconStuffing, it cannot deliver content to disconnected Wi-Fi clients.<\/p>\n\t\t\t<div class=\"moray-accordion\" data-show=\"false\">\n\t\t\t\t\t\t\t<div class=\"clearfix\">\n\t\t\t\t\t<div\n\t\t\t\t\t\tclass=\"btn-group align-items-center mb-g float-sm-right\"\n\t\t\t\t\t\trole=\"group\"\n\t\t\t\t\t\tdata-mount=\"collapse-controls\"\n\t\t\t\t\t\tdata-bi-aN=\"accordion-collapse-controls\"\n\t\t\t\t\t\tdata-target=\"#accordion-1\">\n\t\t\t\t\t\t<button class=\"btn btn-link m-0\" aria-disabled=\"false\" aria-pressed=\"false\" data-action=\"expand\" type=\"button\" data-bi-cN=\"Expand all\">Expand all<\/button>\n\t\t\t\t\t\t<span aria-hidden=\"true\"> | <\/span>\n\t\t\t\t\t\t<button class=\"btn btn-link m-0\" aria-disabled=\"false\" aria-pressed=\"false\" data-action=\"collapse\" type=\"button\" data-bi-cN=\"Collapse all\">Collapse all<\/button>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<ul class=\"accordion\" id=\"accordion-1\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<li class=\"m-0\">\n\t\t\t<h4 class=\"accordion-header\">\n\t\t\t\t<button\n\t\t\t\t\tclass=\"btn btn-collapse m-0\"\n\t\t\t\t\ttype=\"button\"\n\t\t\t\t\tdata-mount=\"collapse\"\n\t\t\t\t\tdata-target=\"#collapse-2\"\n\t\t\t\t\taria-expanded=\"false\"\n\t\t\t\t\taria-controls=\"collapse-2\">\n\t\tPresentations\t\t\t\t<\/button>\n\t\t\t<\/h4>\n\t\t\t<div class=\"collapse\" id=\"collapse-2\">\n\t\t\t\t<div class=\"accordion-body\">\n\t\t\t\t\t\t\t\t\t\t<ul>\n<li><a href=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2016\/02\/wifiads-neighborcast.pdf\">Neighborcast: Enabling Communication Among Nearby Clients<\/a>Ranveer Chandra, Jitendra Padhye, Lenin Ravindranath.<i>Proceedings of IEEE HotMobile<\/i>, Napa, CA (Feb 25-26, 2008)<a href=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2016\/02\/wifiads-hotmobile-neighborcast.pptx\">PowerPoint Presentation<\/a><\/li>\n<li><a href=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2016\/02\/wifiads-beaconstuffing-hotmobile2007.pdf\">BeaconStuffing: Wi-Fi Without Associations<\/a>Ranveer Chandra, Jitendra Padhye, Lenin Ravindranath, Alec Wolman.<i>Proceedings of IEEE HotMobile<\/i>, Tucson, AZ (Feb 26-27, 2007)<a href=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2016\/02\/wifiads-beaconstuffinghotmobile.ppt\">PowerPoint Presentation<\/a><\/li>\n<li><a href=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2016\/02\/wifiads-wifiadstechfest.pptx\">WiFiAds: Delivering Location Sensitive Ads Using Wireless Networks<\/a>Ranveer Chandra, Jitendra Padhye, Lenin Ravindranath, Alec Wolman.<i>MSR TechFest Poster<\/i> (March 2007)<\/li>\n<\/ul>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/li>\n\t\t\t\t\t\t\t\t\t<\/ul>\n\t\t<\/div>\n\t\t\n<p><em>The WiFiAds project is a joint collaboration between the <\/em><a href=\"https:\/\/www.microsoft.com\/en-us\/research\/group\/networking-research-group\/\"><em>Networking Research Group<\/em><\/a><em> at Microsoft Research, Redmond and the <\/em><a href=\"https:\/\/www.microsoft.com\/en-us\/research\/group\/mobility-networks-and-systems\/\"><em>Mobility, Network and Systems Group<\/em><\/a><em> at Microsoft Research, India.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Delivering Location-Based Content to Clients Over Wi-Fi Networks Overview Many consumers carry portable electronic devices, smartphones, personal digital assistants, or laptops that can connect to Wi-Fi networks.
