Wireless Sensor Network (WSN) is a broad network consisting of a number of sensor nodes in it. This network may be in simple or clustered form for efficient data transfer. WSN is used mainly for monitoring and data aggregation purpose. An opponent may try to catch the data by attacking the source node sensing an event or by compromising any other node in network. A best plan of opponent may be to attack the sink node which is the aggregation point for the whole network. So, there comes a need to secure the sink node first. A very efficient scheme to secure the location privacy of sink node is proposed in this paper. It tries to secure the location of sink node by making it anonymous from the network. The blast technique is used for security purpose. The proposed scheme is a trial to improve efficiency of blast scheme in terms of both energy and delay.
