INTRODUCTIONHere we present the bubble-sensing system

that support the persistent sensing of aparticular location as re!uire" by userre!uests # Conceptually a user with a phonethat has opte" into the bubble-sensingsystem $isits a location of interest presses abutton on his phone to a%& the sensingre!uest to the location an" then wal's away #

 The sensing re!uest persists at the locationuntil the timeout set by the initiator is reache"#
