Abstract

With the rise of RFID technology, the so called internet of things for managing supply chain events has gained increasing attention. This paper proposes a peer to peer broker network on top of existing specifications for this infrastructure. With the broker network, event based communication is enabled for the internet of things. However, the main contribution of this paper is a mechanism to optimize event queries for in-network processing of supply chain events. Here, models of supply chain processes are exploited for optimizing event queries and enabling improved mapping of query operators to the broker network. Experiments are presented which show that the proposed mechanism reduces network load compared to existing approaches.
