A multi-hop mobility management protocol for heterogeneous wireless networks

摘要

Purpose - Mobility management for single-hop cellular networks has received much research attention in the last few years. One of the research challenges for 4G wireless systems is the design of mobility management techniques that integrate cellular and ad-hoc networks. Currently, there are no structured mobility management schemes for these heterogeneous multi-hop networks. This paper aims to address these issues.rnDesign/methodology/approach - This paper describes techniques for tracking a mobile node (MN) in an integrated architecture with minimum overhead. This paper proposes group rerouting concept Findings - The paper implements and evaluates the proposed protocol by using the network simulator (NS-2). The proposed protocol increases performance compared to broadcasting schemes. Research limitations/implications - This scheme considers devices with two interfaces only. Practical implications - The paper proposes a scheme to extend the coverage of cellular base stations by using ad-hoc devices.rnOriginality/value - This paper describes techniques for tracking an MN in an integrated architecture with minimum overhead. This scheme is independent of the routing protocol used in a multi-hop network.
