Store-and-forward tree protocol

In this paper, we proposed a store-and-forward tree protocol based on IEEE 802.15.4 non-beacon mode network. The tree topology protocol has advantage of simplicity and quickness. Especially, the mobile sensor node such as unmanned vehicle and smart phone has been utilized various application fields as disaster monitoring, environment data collection. The store-and-forward function is necessary for this area. In order to apply the sensor network, we implemented tree based protocol and verified by experiment using TI CC2530 ZigBee nodes.
