Mobility in hybrid networks architectures

The demand for wireless mobile Internet access is driven by the continuing emergence of new multimedia services and applications. Thus, the overall traffic characteristics for a wireless Internet network such as a ´WiFi´ (i.e., IEEE802.11b) system can include a wide range of dynamic traffic properties (e.g., asymmetric up and downlink message size, desired data rate and message latency, message-flow probability, etc.) that are dependent on the type of Internet service or application from each of the users on the network and the wireless terminal´s capabilities. Combining the high data rate of IEEE 802.11 wireless LANs and multihop connectivity of ad hoc networking, hybrid networks are an attractive solution for ubiquitous mobile access to the Internet. In this paper it is analyzed a routing protocol named flexible mobile access routing protocol (FMARP). Simulation results show that this routing protocol provides reliable data delivery, and swiftly reacts to the network changes with low overhead.
