Recording information of the entry and exit of a target through the boundary of the deployed region is highly essential in wireless sensor network. In this paper, sequential boundary node selection (SBNS) and distributed boundary node selection (DBNS) algorithms are proposed to find out the boundary nodes of the wireless sensor network with or without presence of obstacles over the deployed region. Besides, a target detection protocol is proposed to detect the entry and exit of the single target using those boundary nodes. Simulation results show that the selection of boundary nodes in our protocol is almost close to the optimal one and time of selecting the boundary nodes would not increase rapidly with increase in size of the wireless sensor network.
