Wireless sensor networks are Ad-hoc networks which contain a set of nodes which have limited computational power and limited
power resources. The usage of sensor networks is rapidly growing due to their small size and easily deployment. It means that we can easily
expand and shrink such network, so sensor networks are more flexible as compare to the other wired networks. Due to this flexible nature, such
networks have many applications in various fields. Object tracking is such one of the most important application of sensor network. As the
energy resources are limited in the sensor node so full utilization of the resources with minimum energy remains main consideration when a
wireless sensor network application is designed. Power is supplied with the help of batteries fitted with the sensor node and is not easily
replaceable. In order to maximize the lifetime of sensor networks, the system needs aggressive energy optimization techniques, ensuring that
energy awareness is incorporated not only into individual sensor nodes but also into groups of cooperating nodes and into an entire sensor
network. In this paper we evaluate the performance of an energy saving routing protocol which tracks the object with minimum number of
sensor nodes with the help of OMNet++. For this purpose Node-to-Node Activation Scheme(NNAS) is designed which works on the basis of
protocol called, Node Base Routing protocol (NBR) in which next node is activated by the previous node until the object remain in the sensor
