|Abstract:||Mobile communication is rapidly getting popular in the telecommunication world. Capabilities of wireless networks are improving at a steady pace. This dissertation work deals with a mobile ATM network, called Ethersim . Ethersim is a simulator tool to model multimedia-oriented integrated service ATM networks with mobile hosts and wireless links. It provides the capability to specify a cellular wireless ATM network topology and various host mobility patterns. The architecture of Ethersim employs five special entities: a map, a mover, switches, mobile hosts, and basestations. In Ethersim four types of communication are possible: static host to static host, static host to mobile host, mobile host to static host, mobile host to mobile host. The mobile scenario is comprised of mobile terminals, basestations and ATM switches. ATM switches and basestations belong to the fixed network. Mobile terminals can directly connect only with basestations. As the mobile terminal moves from one zone tc, another, it starts a registration process in the new zone. Basestations then start the virtual circuit (VC) reestablishment procedure to direct the data to the mobile terminal. In this dissertation, all the above mentioned communication types are implemented and evaluated. The Rebuild rerouting policy is used. The performance of this policy is also discussed using the indices of per-packet delay; constant bit rate (CBR) source, throughput etc. The source code for the simulation is written in JAVA (JDK1.1.4) and has been built on WINDOWS-95/98 environment.|
