This  paper  proposes  a  new  application  framework  for  group  tour  guiding services  based  on  RFIDs  and  wireless  sensor  networks.  We  consider  a sensing  field  mixed  with  multiple  independent   tourist  groups,  each  with  a leader and several members.

Members  of  a  group  will  follow  the  moving  path  of  their  leader,  but  may  occasionally  roam  around  randomly  on  their  own  interests.  Sensor  nodes  have to track leaders' locations and maintain guiding paths from members to  leaders.

A  member  may  inquire  where  his/her  leader  is,  and  a  leader  may  "recall" his/her  members.  We  propose  a  feasible  solution  to  such  an  application  by using  existing  technologies  and  off-the-shelf  components.  A  group  guiding protocol is presented. The design enables
