TL;DR
This paper presents an extension for the publish/subscribe paradigm that can effectively support push-oriented LBS, and shows how this paradigm can be adapted to address the needs of location-based services.
Abstract
The advance in wireless networks and in positioning systems has led to a new class of mobile applications: location-based services (LBS). LBS offer highly personalized services to mobile users based on their locations, user profiles and static and dynamic content information. The publish/subscribe paradigm is an information dissemination model appropriate for the implementation of LBS. However, existing publish/subscribe systems do not include location information in their models. In this paper we present an extension for the publish/subscribe paradigm that can effectively support push-oriented LBS.

It is proved that for predicates reducible to conjunctions of elementary tests, the expected time to match a random event is no greater than O(N 1 ) where N is the number of subscriptions, and is a closed-form expression that depends on the number and type of attributes.
