ggf. zzgl. Versand

Mobility Management &amp, Route Optimization issues for Wireless Networks are presented in detail. IP-based Networks, PSTN-based Networks and ATM-based Networks backbones have been considered for developing mobility management technique. In IP-based backbone network, a route optimization scheme is proposed to improve the performance of Mobile IP having some apparent drawbacks like triangular routing problem, home agent overloading etc. An encapsulation at one- level up in the hierarchy is performed to improve the handoff delay and the simulation is carried out on NS-2 simulator. In PSTN-based backbone networks, a protocol is proposed and an analytical modeling is carried out where the location registration can be finished prior to the arrival of a MT at the new network to support the inter-system roaming. For an ATM-based backbone network, a design and prototyping of a mobility support ATM network is proposed to improve the handoff time, cell loss and call setup time. Further, an improved mobile location management for wireless ATM networks is proposed and analyzed to improve the performance in terms of number of hops required for location managements.

Before now, all telephony services are based on the circuit-switched networks, known as the Public Switched Telephone Networks (PSTN). But nowadays, a new trend has emerged that provides telephony services over internet protocol networks, referred to as Voice over IP (VoIP) or IP telephony. There are a few driving force and motivational factors that are behind the VoIP network - the cost savings, the voice and data applications' integration etc are the crux of the innovation. The cost saving is achieved mainly by reduced cost of making a long distance call, maintenance, deployment, management etc., while the integrated applications of voice and data are teleconferencing, integrated voice mail and email, the call distribution intelligence and automation. Therefor, with this era of innovative business practices in information technology that involves voice and data networks integration, both transmitted over the internet and implemented on a local area network (LAN).This book is undoubtedly beneficial to Small and Medium sized businesses for convergence of data and voice networks in their existing data network to accommodate the VoIP solution in the same LAN.

Traditional telephony last about 100 years in use as the basic voice communication because of its reliability that satisfy the normal needs. Packet switching network, especially the Internet, which rapidly spread , attract more and more applications, because of its flexibility and efficiency. One of the most important applications is VoIP, which transmit voice in the same method of transmitting data, taking into account that voice is a real time application. Once we can transmit the voice over IP network, we do not need to route calls using the expensive and large central switches of PSTN, since we can route the calls in the same manner that we route data in IP network. This is the task of the soft switch, soft switch may seem to be the counterpart of central office or PBX of PSTN network. Finally, this project outlines the overall system of VoIP communication, and then show how to implement a whole telephone system based on IP protocols. The implementation of this project will improve the telephony service and management in (IUG).
