Disclosed is a method (500) for dynamically identifying locations of a plurality of mobile nodes (120) in a time division multiple access (TDMA) based ad hoc communication network (100), wherein one or more of the mobile nodes (120) are being moved in and out of a predefined region (150). The method comprises allocating (520) a hello slot in a dedicated channel of the TDMA based ad-hoc communication network (100) to each of the mobile nodes (120) and announcing (525) the allocation to the mobile nodes (120) through hello slot allocation map, receiving (530) location information from each of the mobile nodes (120) during their hello slot and determining (535) mobile nodes (120) that are inside the predefined region (150) based on the received location information, allocating (545) a data slot to each determined mobile nodes (120) inside the predefined region (150) and announcing (550) the allocation to the mobile nodes (120) through data slot allocation map, and receiving (555) updated location information from each determined mobile nodes (120) during their data slot.
