Distributed Processing of Spatial Alarms: A Safe Region-Based Approach

Spatial alarms are considered as one of the basic capabilities in future mobile computing systems for enabling personalization of location-based services. In this paper, the authors propose a distributed architecture and a suite of safe region techniques for scalable processing of spatial alarms. The authors show that safe region-based processing enables resource optimal distribution of partial alarm processing tasks from the server to the mobile clients. They propose three different safe region computation algorithms to explore the impact of size and shape of the safe region on network bandwidth, server load and client energy consumption.
