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 networks, nodes are connected at discrete periods of time. This disconnection may last for long periods in suburban and rural areas. In addition, mobile nodes are energy and buffer sensitive, such as in mobile sensor networks. The limited power and storage resources, combined with the intermittent connection have created a challenging environment for inter-node networking. This type...
A base station (BS) transmits (Tx) and receives (Rx) signals to and from multiple mobile users (MU) through a two-way amplify and forward (AF) relay station (RS) using a two-phase protocol. The BS and the RS are both equipped with multiple antennas. In the first phase (time or frequency), the BS and all MU transmit their signals to the RS. In the second phase, the relay transmits towards the BS and...
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...
This paper deals with an autonomous cognitive network management architecture which aims at achieving inter-network (horizontal) and inter-layer (vertical) cross-optimization. The proposed architecture is based on the so-called Cognitive Managers transparently embedded in properly selected network nodes. The core of each Cognitive Manager are the so-called thinking modules, which are in charge of...
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...
Low resource availability in Mobile Ad hoc NETworks (MANETs) requires efficient utilization of resources and imposes severe demands on routing protocols, motivating their study, since the existing (for wired networks) routing protocols perform poorly, due to the unique characteristics of MANETs. The Dynamic Source Routing (DSR) protocol is one of the most important, simple, and efficient reactive...
In order to communicate among themselves and with the devices on the Internet, a Mobile Ad-hoc NETwork (MANET) node needs to configure its interface(s) with IP address(es). MANET is a multi-hop network often consisting of mobile devices such as mobile phones, PDAs, laptops with wireless interface(s). Due to some of the MANET inherent characteristics such as mobility, multi-hop and ad hoc, manual configuration...
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...
In this paper, we investigate the power allocation problem involving how to multiplex cooperative routes in multi-source ad hoc wireless networks. The aim is to provide a route-multiplexing scheme with minimal total power consumption given spectrum efficiency constraints. Three protocols: full combination with interference (FCI), full combination with time sharing (FCTS) and selection between interference...
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...
In this paper we present a network utility maximization (NUM)-based architecture developed under the defense advanced research projects agency (DARPA) control-based mobile ad hoc networking (CBMANET) program, namely mobility-aware resource coordination for optimization of networking infrastructure (MARCONI). MARCONI plays a fundamental role not only in advancing NUM theory to address tactical communication...
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...
