Mobile devices can exist in many forms. IEEE 802.11 and IEEE 802.16 create a heterogeneous network. Heterogeneity implies that some devices are more powerful than others, and some can be servers while others can only be clients. Typical IEEE 802.11 b/g/a is considered up to 54 Mbit/s, WiMax IEEE [802.16] has the specification of Medium Access Control (MAC) also PHYsical (PHY) layers. The results analyze the validity of broadcast and multicast in heterogeneous networks. The basic idea is to enhance the performance of multicasting and broadcasting in heterogeneous network.
