Patent ID: 7944905

Claim:
A method for dynamically identifying locations of a plurality of mobile nodes in a time division multiple access (TDMA) based ad hoc communication network, wherein one or more of the mobile nodes are being moved in and out of a predefined geographic region, comprising: at a central console: allocating a hello slot from a plurality of time slots in a dedicated channel of the TDMA based ad hoc communication network to each of the mobile nodes and announcing the allocation to the mobile nodes through hello slot allocation map; receiving location information from each of the mobile nodes during their hello slot and determining mobile nodes that are inside the predefined geographic region based on comparing the received location information to the predefined geographic region; allocating a data slot from the plurality of time slots to each determined mobile nodes inside the predefined geographic region and announcing the allocation to the mobile nodes through data slot allocation map; and receiving updated location information from each determined mobile nodes during their data slot and hello slot.
