In order to provide communication service in the Intermittently Connected Mobile Networks (ICMN) where there is only intermittent connectivity between mobile nodes, a variety of epidemic-style routing algorithms have been proposed to achieve high message delivery probability. However, current works do not address the realistic environment that a message is split into multi frames to be transmitted...
One or more mobile nodes with mobile router(s) form a mobile network. Mobile router acts as the single point of attachment to the internet. As the configuration of mobile network changes, mobile router keeps track of its registered mobile nodes. Presently, a scheme has been designed for group registration of mobile nodes under a single home agent. In this paper, a communication scheme is proposed...
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...
Among the route optimization schemes in NEtwork MObility (NEMO), the prefix delegation-based schemes perform better than other schemes. Since the prefix delegation-based schemes are designed for communication between a mobile network and a wired network, they lack evaluation for the case of intra mobile network communication involving MIPv6 incapable hosts in a mobile network. We evaluate prefix delegation-based...
Message Ferrying (MF) is a recently proposed scheme to restore a Mobile Ad Hoc Network (MANET) from partitioning. Despite of the effectiveness in partition restoration, it sometimes suffers from long delay caused by the poor design of ferry route. The Message Ferry Route (MFR) problem has earlier been studied to minimize this drawback of MF schemes. In this paper, we argue that a dynamic way of determining...
HMIPv6(Hierarchical Mobile IPv6) adopts hierarchical architecture to manage the communication between mobile node(MN) and correspondent node(CN) by introducing a mobility anchor point(MAP) so that it may greatly reduce signaling cost during MN movement. However, it also brings about some new problems, one of which is the issue of the route. When a MN moves to some special location, there maybe exists...
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...
Given a wireless network where each link undergoes small-scale (Rayleigh) fading, we consider the problem of routing a message from a source node to a target node while minimizing energy or power expenditure given a fixed time budget, or vice versa. Given instantaneous channel state information, we develop tight hyperbolic bounds on the quantities of interest and solve the related optimizations in...
The next generation broadband wireless access networks are expected to support a variety of multimedia rich applications which can lead to very high traffic demand. With the development of high speed radio access technologies the backhaul network can become the bottleneck if not upgraded and configured optimally to support the expected increase in date rates and traffic demands. To deliver high data...
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...
