Many of modern location-based services are often based on an area or place as opposed to an accurate determination of the precise location. Geofencing approach is based on the observation that users move from one place to another and then stay at that place for a while. These places can be, for example, commercial properties, homes, office centers and so on. As per geofencing approach they could be described (defined) as some geographic areas bounded by polygons. It assumes users simply move from fence to fence and stay inside fences for a while. In this article we replace geo-based boundaries with network proximity rules. This new approach let us effectively deploy indoor location based services and provide a significant energy saving for mobile devices comparing with the traditional methods.

This paper describes an algorithm for discovery of convoys in database with proximity log. Traditionally, discovery of convoys covers trajectories databases. This paper presents a model for context-aware browsing application based on the network proximity. Our model uses mobile phone as proximity sensor and proximity data replaces location information. As per our concept, any existing or even especially created wireless network node could be used as presence sensor that can discover access to some dynamic or user-generated content. Content revelation in this model depends on rules based on the proximity. Discovery of convoys in historical user's logs provides a new class of rules for delivering local content to mobile subscribers.

The usage for the similar server is described in this article from CFIC-2013: Local messages for smartphones (paper in arxiv.org). Here is yet another Open Source implementation: Uniqush-Push. And here is a useful server with free limit: PushOver. Windows Azure supports Notification Hub.
Our Spotique project uses push-notifications

After installation, the Beacons begin transmitting 2.4 GHz Bluetooth® signals, similar to WiFi. They can communicate with smartphones that are as close as four inches away, or as far as 30 feet away.
One remark: actually such a beacon could be replaced by Wi-Fi phone. Our SpotEx approach could be used here.
Just a quote:"We believe the whole indoor-navigation idea is wrong. There is no need to map every inch of the physical world and get X,Y coordinates. It's all about the context and placing tiny beacons in the doors, next to check-out, next to GoPro camera in the Best Buy. They you detect the proximity and the context and trigger an action." It is what SpotEx is about. Why do we need location if we can distribute data on the base of context info?

It is what our Spotique is for.
