Abstract
Mobility support is among the most defying topics into publish/subscribe systems. In fact, the mobility of the subscriber causes message loss, an increase in the latency and in the overhead. We resort to the proactive caching by defining a procedure for selecting the candidates brokers for being the caching points. We define a metric named threshold, and we select the brokers which have the values of weight superior to this metric. Added to that, we extend our approach by the select closest criterion for minimizing the delay of transfer. So, we select the closest caching point for the transfer of messages in the cases of a handoff to a non caching point. Hence, we have succeed to minimize the buffering costs and the delay of transfer.
