First responders, including structural engineers and firefighters, inspect buildings and identify the structural
integrity of buildings within a disaster affected area. The performance of their inspection and dissemination
of the assessment information are critical to Urban Search and Rescue (US&R) operations.
This paper presents an innovative approach for structural assessment and resource requests through
an application – Supporting Urban Preparedness and Emergency Response using Mobile Ad hoc Network
(SUPER-MAN). The goal of this research is to address challenges encountered in the current practice for
structural engineers and first responders to inspect and disseminate building damage assessments and
resource requests more efficiently to support US&R. The SUPER-MAN system is equipped with Radio Frequency
Identification (RFID) tags, as the storage device of assessment information on the disaster site,
and a Mobile Ad hoc Network (MANET) with a Dynamic Source Routing (DSR) implementation for communication.
SUPER-MAN strengthens responders’ situational awareness, reduces confusion of inconsistent
assessment formats, and automates information dissemination and editing. As a result, lifesaving
operations are adequately prioritized, risk of first responders are minimized, and requests of response
resources are facilitated. Results obtained from field trials carried out at the Illinois Fire Service Institute
with a simulated disaster scenario and computer simulations of the MANET are presented to highlight the
benefits provided by SUPER-MAN.

Future ‘on-demand’ computing systems, often depicted as potentially large scale and complex Service-Oriented Architectures, will need innovative management approaches for controlling and matching services demand and supply. Centralized optimization approaches reach their bounds with increasing network size and number of nodes. The search for decentralized approaches has led to build on self-organization concepts like Autonomic Computing, which draw their inspiration from Biology. This article shows how an alternative self-organization concept from Economics, the Catallaxy concept of F.A. von Hayek, can be realized for allocating service supply and demand in a distributed ‘on-demand’ web services network. Its implementation using a network simulator allows evaluating the approach against a centralized resource broker, by dynamically varying connection reliability and node density in the network. Exhibiting Autonomic Computing properties, the Catallaxy realization outperforms a centralized broker in highly dynamic environments.
