Abstract

The utilization of multimedia devices is growing rapidlyin surveillance and monitoring applications. These multimediasurveillance systems need to process large amountsof multimodal sensor data in order to detect events and objects.While processing this large amount of data, the systemfaces many processing and network bottlenecks. Thedesign of efficient multimedia surveillance system requiresintelligent architectural decisions and performance evaluationto cope with these resource demands. One critical issueamong all these architectures is task assignment amongprocessing units. To study the effect of this task assignmenton system performance with quantifiable performancemeasures is very useful and challenging. We define a FunctionalityDelegation Coefficient which abstracts the delegationof functionality among processing units of a distributedsurveillance system and show its effect on event blockingprobability and response time. Simulation and real implementationresults are provided to validate the model.
