1. A method of operating a sensor net, comprising:
- detecting access attempts by at least one mobile device to a plurality of nodes within said sensor net;
calculating probabilities of future access attempts to said nodes within said sensor net; and
selecting at least one node of said plurality of nodes to perform collection point services for said sensor net using said calculated probabilities of future access attempts.

Abstract
Representative embodiments are directed to distributed sensor systems from which measurement data is extracted using mobile devices. Representative embodiments record access attempts by the mobile devices and calculate the probabilities of future access by a mobile device to sensor devices using the recorded information. Collection points are selected in response to the probabilities of future access. Additionally, memory management and data prioritization may occur that is at least partially dependent upon the probabilities of future access.
