在Linux下做的QuadTree的程序

Examples:

1. when running Grid for testing GLS queries only (i.e. there's no data traffic
   in the network.), compile with -DTEST_QUERY flag.
2. when testing Grid with wake and sleep scenarios (i.e. running ns with ws-* wake
   sleep scenario files), use hgps-ws.tcl file.
3. An example of running Grid:
    ns cmu/scripts/run-2Mb.tcl -rp cmu/hgps/hgps.tcl -x 2900 -y 2900 -ud 100 -cp
scen/600/cbr-600-300-4-128 -sc scen/600/scen-2900x2900-600-0-10-1 -stop 300 -tr out.tr

-ud specifies the update distance for how often a location update is sent out

4. To analyze the trace file, run cmu/scripts/hgps.pl /tmp/ns RTR <num nodes>
