In mobile networks, when the mobile terminal (MT) has an active call while crossing the boundary of two systems, it is required that the existing connection should not be lost. To meet this demand, the signalling protocol of mobility management must be designed for supporting location registration and call delivery for roaming users who move beyond their home network. The objective of this study is...
Next generation networks require an efficient route optimization scheme, optimized specially to support network mobility. The paper proposes a Mobile IPv6 based route optimization technique to reduce the overhead and enhance the performance of a mobile network. The proposed scheme uses root Mobile Router (top level MR in the nested network) to perform route optimization on behalf of all active mobile...
Route optimization support in mobile networks is one of the most important concerns in Next Generation Networks (NGNs). NGNs require an efficient route optimization scheme, optimized specially to support nesting of mobile networks. We propose an Extended Mobile IPv6 route optimization (EMIP) scheme to enhance the performance of nested mobile networks. EMIP scheme is based on MIPv6 route optimization...
The throughput of a wireless mobile ad-hoc network (MANETs) improves by using concurrent transmissions at the MAC layer among neighboring nodes. Several such protocols have been proposed in the past, but all of them are used for single-hop transmission to enhance the throughput. In this paper we propose a model for improving the throughput of multi-hop static ad-hoc networks (SANET) line topology...
Due to bandwidth constraint and highly dynamic topology of mobile ad hoc networks, supporting quality of service (QoS) is a challenging task. In this paper, we present two efficient route recovery mechanisms for QoS routing based on an extension of the AODV (ad hoc on demand distance vector) routing protocol that deals with delay and bandwidth constraints. One is based on route maintenance by intermediate...
In this paper, we present a game-theoretic model of intrusion detection systems (IDSs) for Mobile Ad hoc Networks. In most of the existing intrusion detection systems for MANETs, a detection system sits on every node, which runs all the time, which is a costly overhead for a battery-powered mobile device. We have used game theory to model the interactions between the intrusion detection system and...
