This issue is to improve the performance of OpenWSN networks,, specifically on network forming duration:
A network is formed, is defined as each node in the network:
synchronized to the network
joined the network (having key to encrypt data frames)
obtain RANK for routing
Have at least one Tx cell installed in schedule
After this issue is fixed, we should have the 76 motes over OpenTestbed form a networking within around 10 minutes.
