Kunz: Subscriber Mobility in Pub/Sub Systems
Neighbor Graph (NG)
,Is an undirected graph with a
number of edges that represent the mobility paths between the
vertices
,Provides
the abstractions to identify the candidate subset of next potential
brokers
,Forms
the basis for pre-loading the subscriber context one hop ahead of its
current broker
,Automatically generated and adaptively changes according
to the mobility graph
,A timestamp based LRU method can
be used to ensure the freshness of NG and remove the outlier
edges
,Is stored in a
distributed manner
