QoS management in mobile IP networks using a terminal assistant

Abstract

SUMMARYThis paper describes a signalling environment for Quality of Service (QoS) negotiation and advance resource reservation in mobile IP networks. This environment is built in conformance with the generic signalling environment, which is standardized by the NSIS IETF working group. The advanced resource reservation protocol, called MQoS NSLP, is based on the QoS NSLP signalling application. It provides to mobile terminals the QoS required based on the user's mobility and QoS profi le. In this work, we investigate the use of some techniques of the AI (Artifi cial Intelligence) domain to implement a user interface called NIA (Negotiation Individual Assistant) in order to determine the QoS profi le and negotiate the QoS parameters in the new domain after the handover. Therefore, we use connectionist learning in the management of the negotiation profi les and agent technology to help the user choose the best service provider, dynamically negotiate the QoS on the user's behalf, and follow the user's behaviour to be able to anticipate the negotiation and manage renegotiation. The advance resource reservation is based on an object MSpec (Mobility Specifi cation) which determines the future location of the mobile terminal. The MSpec object is a part of the mobility and QoS profi le and is determined by the NIA in the mobile terminal.

Cellular IP address provisioning in a heterogeneous wireless network

“…At this point, C can initiate a communication session with device D located in domain-2. It is worth mentioning that, interdomain call is accomplished without using mobile IP technique, which keeps the same IP address of the mobile IP device [17][18][19]. Mobile IP allows the device to move from one domain to another using the same IP address.…”
