One of the major issues in MANETs is to track the location of the users. Since mobile users are free to move within the coverage area, the network can only maintain the approximate location of each user. When a connection needs to be established to a particular user, the network has to determine the user's exact location. The operation of the mobile terminal informing the network about its current location is known as location update, and the operation of the network determining the exact location of the mobile user for the purpose of call notification is called terminal paging or searching. Over the past few years several location update schemes have been developed.
