Navigation services in emergency scenes could be an important application of wireless sensor networks for saving human lives. In this paper, we propose a navigation algorithm which emphasizes on safely guiding people to quickly escape from a hazardous area. Our design allows multiple exits and multiple emergency events in the sensing field. At normal time,(More)
We based our protocol on the temporally ordered routing algorithm 2 for mobile ad hoc networks. TORA assigns mobile nodes temporally ordered sequence numbers to support multipath routing from a source to a specific destination node. The algorithm expresses the sequence number as a quintuple. To handle mobility, TORA adopts a link-reversal procedure when(More)
