Mashup Service Conflict Detection and Visualization Method for Internet of Things

Abstract

Many Internet of Things applications provide methods to create mashup services with if-then-else approaches due to its simplicity. When a number of mashup services are increased, it may be suffered by service conflict, that is, mashup services may perform opposite actions or abnormal behavior at the same time. To overcome this issue, this paper proposes the concept of context descriptor to detect service conflict and visualize their situations.
