In future, more wireless devices are connecting to the Internet. These devices are mobile and move within the coverage area of any mobile network. There are two types of mobile network namely Mobile IP and Mobile ad hoc network. This paper will present indoor tracking in mobile ad hoc network or MANET. MANET consists of nodes that are able to communicate wirelessly among themselves. These nodes also serve as routers and can dynamically move around arbitrarily at any speed in any direction resulting in an ever-changing topology. These nodes are stand-alone, mobile and operate on batteries. Due to mobility of nodes, the most challenging issue in MANET is to design a routing protocol that guarantees delivery of packets. Routing metrics used so far are shortest path, link stability, position location, power and bandwidth available. In order to improve network routing performance, a limited casting technique will be adopted which requires the ability to establish position information. Ultimately, the objective of position location tracking is to provide reliable and accurate position of mobile nodes. In this paper, a GPS-free indoor position tracking system has been developed that provides knowledge of geometric location of nodes in MANET. The location tracking not only aids in routing protocol design but also provide security monitoring of the hacker nodes if it enters MANET. Additionally, the monitoring system supports the delivery of packets to all nodes in a given geographic region in a natural way. This type of service is called geographic forwarding.
