Reactive Tuning of Target Estimate Accuracy in Multisensor Data Fusion

Abstract

Dealing with conflicting and target-specific requirements is an important issue in multi-sensor and multi-target tracking. This paper aims to allocate sensing resources among various targets in reaction to individual information requests. The approach proposed is to introduce agents for every relevant target responsible for its tracking. Such agents are expected to bargain with each other for a division of resources. A bilateral negotiation model is established for resource allocation in twotarget tracking. The applications of agent negotiation to target covariance tuning are illustrated together with simulation results presented. Moreover, we suggest a way of organizing simultaneous one-to-one negotiations, making our negotiation model still applicable in scenarios of tracking more than two targets.

Multi-sensor management for data fusion in target tracking

“…The scheme is motivated by the recent research work of Xiong et al in [14]. We modify their scheme and test the revised scheme with more realistic experiments.…”

“…With developments of modern systems through increased bandwidth, wireless communication, and enhanced power, decentralized management becomes more workable for a sensor network. Developing decentralized management technique [14] is becoming an active R&D area again. In this paper, a decentralized method based on game theoretic negotiation is presented for sensor assignment.…”

“…Also, to make the description more concise, we set the two-target scenario discussed in the previous sections for negotiation. (14) where ) (t Poss is a set of offers better than opting out for Agent 2 at time t.

Agent negotiation of target distribution enhancing system survivability

“…This article indicates how a distributed assignment strategy based on game theory helps to enhance the robustness of a sensor network. Another recently published paper 13 deals with target-specific requests for reactive resource allocation using game theoretic negotiation.…”
