Mobility protocols are originally proposed to support ongoing Internet connectivity of hosts or networks in motion. However, the requirement of seamless connectivity in mobile environment and use of route optimization between the communicating nodes have introduced several security vulnerabilities to mobility protocols. In this paper, we explain with illustrative examples major security threats on...
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...
The aviation community is in the process of designing the next generation Aeronautical Telecommunications Network (ATN), based on Internet standards, to provide air- ground communications for the aircraft. Support for mobile networks in the current Internet architecture is provided by the NEtwork Mobility (NEMO) protocol. As currently defined, NEMO Basic Support protocol lacks of Route Optimization...
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...
Network mobility (NEMO) supports the movement of some part of the network that a group of the mobile nodes (MNs) or the mobile routers (MRs) moves together. To support NEMO, the NEMO basic support protocol (NBSP) was proposed. In the nested mobile network, however, the NBSP exhibits pinball routing problem. As the degree of nesting increase, the problem becomes more serious. In this paper, we propose...
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...
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...
Route optimization provides a short path between the mobile node and the correspondent node in mobile IPv6 protocol and makes them communicate efficiently. Some insider attacks were found while analyzing vulnerability of the route optimization. The simulation experiment shows that the insider attacks make the mobile node fail in using optimized route, and it results in performance degradation and...
