Abstract: We propose ID-exchange protocol for Connectionless Location-Awareness Service (CLAS) tolocate mobile nodes in indoor sensor network. When adapting location-awareness service tosensor network, the target system must be designed in accordance with various metrics whichreflect the system requirement. We especially consider sustainability of the existing servicewhich has been provided for its original purpose, such as environmental monitoring. Thedetailed meaning of sustainability here is that, even if location-awareness service is newlyadded to the existing service, the system must be assured to retain a stable network condition,and to deal with newly caused traffic properly. The CLAS ID-exchange protocol is especiallydesigned for fixture and mobile nodes communication to achieve these properties. The protocoloperates on 802.15.4 MAC layer to make mobile node work independently of the procedure tobuild routing table of fixture node, so a stable routing condition can be achieved even if thereare many mobile nodes. Moreover, the dedicated frequency channel is assigned only for thisprotocol, so that traffic caused by location-awareness service can be distributed to anotherchannel. A real system adapting the protocol was implemented to monitor fire and authorities’positions. We verified the overhead and elapsed time for location-awareness. The result showsthe proposed protocol has a high performance in detecting speed, traffic distribution,
