Study on ZigBee Network Routing Based on Nodal Heterogeneity

ZigBee is a kind of low rate, low cost and low power technology to be used in cheap, fixed, portable and mobile devices in wireless personal network. In ZigBee mesh network, the routing algorithms about the two kinds of nodes RN+ and RN- have been studied in this paper. With the increasing number of RN- in the total routers, the packet delivery ratios decrease slowly, but the difference is smaller; the routing overheads decrease one by one while the 40% and 60% percentage of RN-, the overhead are 40.2 and 49 respectively; the end to end delay is almost 0.043 s with the 40% and 60% percentage of RN-. The results show that the 40% percentage of RN- is more excellent in deciding routing performance.
