A survey of cellular IP in the next generation of network protocol

The main objective of mobility management in wireless data communication is to allows networks to search and locate (location management) mobile users while maintaining it’s connections (handoff management) whenever users move into a new network. Management of location and handoff divided into macromobility (for managing inter-domain network) and micromobility (for managing intra-domain network).For macromobility management, IETF has adopted Mobile IP and had perform very well for managing inter-domain mobility.However Mobile IP suffer from handover performance in intradomain network which is inefficient for mobile user with frequent handoff. For this defect,cellular IP protocol has been considered for managing intra-domain network for it’s fast handoff and interoperability with Mobile IP. This paper we present a review of different micro-mobility management protocols available to date. We also discuss various issues and challenges regarding mobility management for the next generation network protocol

Ad Hoc Mobility Notification in Wireless Infrastructure Networks

Hybrid networks composed of a wireless infrastructure network providing Internet access to an underlying ad hoc network are more and more attractive due to their low installation cost. In these all-wireless environments, performance is a key issue as radio bandwidth is scarce. Handoffs management is particularly important as these networks are likely to be highly mobile. Mobility notification should therefore be optimized in order to limit signaling overhead while keeping a good reactivity against terminals mobility. This article presents and studies by simulation different level optimizations applied to a modified Cellular IP protocol
