A wireless network according to the standard IEEE 802.15.1 4 [] was developed by IEEE New Standards Committee (NesCom) for use in wireless communications, close-up with speed of sending data low. (Low data-rate) focusing on battery life for a long time. And to create a network of various models according to the standard IEEE 802.15.4 the details of the physical layer (Physical layer) and MAC sub layer (MAC Sub-Layer), which are further to suit the industry in each category. And as Zigbee MiWi etc.
today's standard IEEE 802.15.4 [] is 2 standards have been widely accepted. In the field of wireless communication is low, satisfy working sensor node Being used in different areas. [3 4,,5], such as measurement and storage of agricultural environment (Agricultural environment monitoring) control the motor transport. (Transport planning) management system warehouse (Logistic planning) and the test structure of hosts (Structural testing).Often used to collect the data and forward data (Collecting and forwarding) through a node to the node collection base. By linking together with the sensor node transmission multiple fry (Multi-hop), [1112, the 13].
