Integrated Sensing: Network Support for Distributed Sensing Applications

At the core of the next generation of networking applications and technologies lies the potential of embedding sensing and actuating capabilities in the network so as to support a variety of monitoring and controls applications. In this proposal we target applications that require stringent quality of service guarantees, e.g., applications needing global snapshot(s) of the state of a physical attribute,or requiring correlating various such attributes. For example, one might jointly track the wind speed and the density of a given pathogen to create evolution models. To support such applications while achieving high sensor utilization we propose to investigate two complementary problems:(1) What are fundamental characteristics and requirements ofestimation and control applicationsdrawing spatio-temporal data from networked sensors; and(2) What types of network support, e.g., sensing `primitives' and resource/traffic management mechanisms will be critical to enable wide-spread shared usage of such networks.Due to the expected heterogeneity of sensor networksand possible mismatch between a sensor's `capacity' to processqueries and the network bandwidth delay product,achieving timely coordinated responses from a potentially largeset of sensors shared by multiple users may be difficult.This is exacerbated by the inherent asymmetry of communications associated with such sensing activities, i.e., one-to-many queries resulting in many-to-one sensor responses. As a result one can expect unpredictable bursts of traffic, network hot spots, and degradation in performance. As part of the proposed researchwe will investigate these problems from the perspective ofthe applications, the network and the sensors.
