“…There are three main approaches to maintain the infrastructure (chained by stability of the distributed infrastructure, it means that each stage represents maturity of the infrastructure and is used by controllable takeover mechanism): 1) all Smart Space members, SIBs, are able to see all packets and applies incremental routing technique to forward the message to the appropriate Smart Space member, SIB 2) mSIBs are managing and determining the packets to be send and forward to the appropriate Smart Space member, SIB 3) when SIB routing mechanism has query update capabilities, then this method is used. It is the case when routing technique is extended by the local information that particular SIB can provide [9] The mechanism of determination which Smart Space member is to process a message and allow other to disregard the message is based on incremental key routing [6].…”
