Route optimization for nested Mobile Network is an important issue of Network Mobility (NEMO), and prefix delegation is one of the promising optimization schemes. However, the policy of prefix delegation is seldom discussed when this technology is applied in nested NEMO. The problems that may be encountered when applying the basic prefix delegation to nested NEMO are analyzed and identified, and a...
In sparse mobile sensor networks, nodes have a small number of neighbors with intermittent connectivity. This paper presents a new networking protocol for this type of network, aimed at maximizing system performance in terms of both delay and reliability. The system is motivated by the observation that many applications on this type of network have two kinds of co-existing data packets: those with...
MOBIKE, which is an extended specification of IKEv2, has been proposed as a technology to set up VPN connections in a mobile environment. An advantage of MOBIKE over a similar mobile technology, Mobile IP, is that the handover time is short. However, since MOBIKE uses only a single tunnel terminating device, if it is applied to a network in which mobile terminals move about over a wide area, connection...
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...
Among the schemes, proposed in the literature to solve the route optimization problem in NEtwork Mobility (NEMO), the prefix delegation-based schemes perform better than other schemes. Depending on the way the prefix are delegated, the prefix delegation-based schemes result in difference in performance under different speed at various distance from the home network (network to which mobile network...
Nowadays, the requirement of Internet is increasing in more and more heterogeneous scenarios; especially in mobile platforms, such as Planes, trains and buses. NEMOWG (network mobility workging group) a new working group in IETF (Internet Engineering Task Force) is formed to provide mechanisms to manage the mobility of a network as a whole, enabling that network to change its point of attachment to...
Localized mobility protocols are designed to address many of the drawbacks such as additional signaling and over-the-air tunnel overhead associated with global mobility protocols like Mobile IPv4 and Mobile IPv6. Proxy Mobile IPv6 is one such network controlled localized protocol defined in the IETF Although Proxy Mobile IPv6 can resolve longer binding update and tunnel overhead related issues when...
With the maturity of mobile application environment and the popularity of Bluetooth device, researchers focus on data transmission in Bluetooth mobile Peer-to-Peer (MP2P) network. However, QoS of data transmission becomes poor in Bluetooth mobile P2P network because of the limit communicating rate and the mobility of user. In this paper, we propose a novel cross-layer design mechanism, which controls...
A hybrid analysis method for protocol is proposed which combines the power of both manual and automatic methods. At first, it defines a number of attack goals and then studies how to achieve these goals by misusing the messages. An automatic analysis tool is applied in order to reach completeness based on the manual analysis. Some of the found attacks are excluded because of the low feasibility in...
A number of prefix delegation-based schemes have been proposed in the literature to solve the route optimization problem in mobile networks. The route optimization solutions generate overheads and affect the performance of mobile networks. However, currently there is no tool available to aid in the selection of an appropriate scheme for a given mobility scenario. The objective of this paper is to...
Network mobility (NEMO) basic support protocol is an extension mobile IPv6. NEMO signaling is performed with extended mobile IPv6 messages. NEMO basic support protocol is concerned with managing the mobility of an entire network, it provides for devices or vehicles which move to another point of attachment to the Internet. NEMO can maintain sessions established nodes between the mobile network and...
In this paper the optimized handover mechanisms including the dual-interfaces hard handover and network-layer soft-handover are proposed to improve the handover performance when adopting the hierarchical mobile IPv6 (HMIPv6) protocol. A HMIPv6 test-bed based on Linux is set up and a series of experimental studies on network-layer handover are performed. From the test results we can see that the soft-handoff...
Seamless vertical handover is in great focus in contemporary world of research. Multi-interfaced mobile devices are introduced in the market to enable heterogeneous access. The main problem is how to efficiently use these multi-interfaced devices to achieve best data throughput, reduced packet loss and optimized handover. In this paper, the advantages of multihoming approach have been combined with...
Proxy mobile IPv6 (PMIPv6) protocol provides network based IP mobility management to a mobile node without requiring the mobile node to participate in IP mobility related signaling. A PMIPv6 domain contains multiple mobility access gateways (MAGs) and local mobility anchor (LMA), these entities are going to track the mobile nodepsilas movements and advertise the same prefix to the mobile node so that...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
A cross layer design method is presented which is built upon the idea of equivalence classes of key-parameters of several layers in the protocol stack. An equivalence class is composed of all key-parameter tuples which fulfill a desired quality of service. Since different parameter tuples are usually associated with different costs (e.g. transmit power), a cross-layer design can select the most cost-efficient...
