How to get a multicast to wait for all nodes?

[Ryuke]

I have a code that receives gps information from nodes and gives off
its own coordinates via radios connected by Ethernet. but the code
continues to run after receiving only 1 set of coordinates, how do i
get it to wait for multiple nodes to send before continuing

You might provide wth significant part
of the code you have written.

oops. guess that's important, here's part of it

#Get local node network view data from RIB using SNMP over Ethernet
mynodeID = snmpget(RIB_HOS T, MYNODE_ID)
# print '[netge module] MYnode ID =',mynodeID
netdict = snmpwalk(RIB_HO ST,MIB_BASE)
netdict[MYNODE_ID] = mynodeID
print '[netge module] MyNode ID = ',netdict[MYNODE_ID]

sorted_keys = sorted(netdict)
# for key in sorted_keys: print '%s\t\t%s' % (key,netdict[key])
for c in netdict[NODE_LIST][1:]: print '[netge module] NbrNode
%d'% ord(c)

#Create heart beat data packet for multicast xfer
# gpsdata.append( time.ctime())
print '[netge module] mynode location =
',netdict[MYNODE_LOCATION]
# netdict[MYNODE_LOCATION] = ' '.join(gpsdata)
netdict[MYNODE_LOCATION] = gpsdata
print '[netge module] mynode location =
',netdict[MYNODE_LOCATION]
heartbeat = ' '.join(netdict[MYNODE_LOCATION])
print '[netge module] heartbeat=',hea rtbeat

#Send mulitcast heart beat packet of local node view of
network
sock.sendto(hea rtbeat,(MULTICA ST_IP_ADDR, MULTICAST_PORT) )
print '[netge module] multicast send'

#Receive mulitcast heart beat data
#ReceiveHB()
print '[netge module] multicast receive=',sock. recv(1024)

#Create KMZ file for local node view of network
# CreateKMZfile(n etdict)

node = []
latitude = []
longitude = []
altitude = []
kml_nodes = ''
kml_links = ''

MAX_NUM = int(netdict[NUMBEROFNODES])
# MAX_NUM = len(netdict[NODE_LIST])
# print MAX_NUM
