WSN is mainly used at such a place, where the normal wired network configuration is not possible. So, the sensor nodes are deployed over such places to perform monitoring and tracking. Sensor nodes communicate in their transmission range only, so if the sink node is not present in their range, the message will be delivered in multi-hop fashion. There is a high chance that the communication over the networks can be monitored by eavesdropper. Hence, the location of the message originator, called source node of the network is not secure. It is more important to hide the location of the source node for various tracking applications as location information can reveal other critical informations. In this paper, we have proposed a scheme called Multiple Phantom with Multiple Fake Source (MPMF), which is efficient to hide the location of the source node and increases the network lifetime.
