With the rapid growth of wireless technologies and increasing number of mobile digital devices, mobility has been an important element on the Internet. NEMO Basic Support, designed by the Internet Engineering Task Force (IETF) to provide network mobility, is not efficient to offer low latency handoff in the case of nested mobile networks because it produces a long transfer delay and excessively large...
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...
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...
In nested mobile network, traffic should be encapsulated and tunneled for each level of nesting, which leads to increased overhead and sub-optimal routing. In this paper, we investigate a localized mobility management framework and propose a source routing binding update mechanism based on mobile anchor point (MAP) to optimize the route of nested mobile network that supports NEMO basic support protocol...
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...
Network mobility (NEMO) basic support protocol is designed to support network mobility management, and it ensures communication continuity for nodes in the mobile networks. However, NEMO in nested mobile networks suffers from the pinball routing problem, resulting in the long packet transmission delay. Therefore, we propose a domain-based route optimization (DRO) scheme that incorporates the domain-based...
To minimize the large handover delays associated with mobile IPv6 numerous micro-mobility protocols were proposed. In this paper, we consider the mobility agent (MA) based family of micro-mobility protocols such as hierarchical mobile IPv6 and proxy mobile IPv6 and focus on the issue of the bottlenecks that MAs can lead up to under high network load. We propose a Dynamic QoS aware route optimization...
This paper provides a tutorial treatment of recent stochastic network optimization techniques, including Lyapunov network optimization, backpressure, and max-weight decision making. A new technique of place holder bits that improves delay for networking problems with general costs is also presented. An example application is given for the problem of energy-aware scheduling and routing in a wireless...
As the wireless communication and mobile terminal technologies develop, the mobility of consumers rapidly increases. The consumers in this dynamic environment also want to connect their devices and to receive seamless services anywhere, anytime. Network mobility (NEMO) proposed by IETF focuses on the condition where the entire network moves. However, in the (NEMO) basic support protocol', the tunneling...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
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...
