“…To solve mobility problem and improve network performance and signaling/control overhead in such a heterogeneous scenario were proposed. More recently, the issues of cluster backbone and multi-cluster architecture for mobile ad hoc networks were also proposed [18][19][20][21]30,31].This paper addresses the interworking between ad hoc networks and Internet Protocol (IP-based) networks, where we focus on network partitioning can improve or solve critical functions such as mobility management, routing, and broadcast problems. It can be observed in this type of architecture using network partitioning concept may result in scalability for a large network.…”

In recent years, the wireless network has been attracting a lot of attentions, and due to these devices has enjoyed a tremendous rise in popularity. However, the broadcast storm becomes a very serious problem for ad hoc networks to migrate into the overlay networks for the applications of group communications. The main concept of virtual subnet technology is the capability to group users into broadcast domains, which divides a virtual subnet into logic, instead of physical, segments and reduces the traffic overhead. With this characteristic, we propose an interoperability network model integrating self-organizing ad hoc networks and the Internet/a conventional network with the partition of physical/virtual subnets. Moreover, we describe a protocol to establish the virtual broadcast domains by using the IPv6 addressing concept in ad hoc networks and perform IP-based network communications in a multi-switch backbone. Since the virtual subnet technology functions by logically segmenting the network into different broadcast domains, packets can only be delivered between fixed/mobile nodes with the same virtual identity. Therefore we can prevent the broadcast storm problem in MANET. The hierarchical networks, physical/virtual subnets, addressing method, and mobility management are described, and some performance issues are evaluated.other, but has no fixed links like wireless infrastructure network. Each node acts as a router and is responsible for dynamically discovering other nodes it can directly communicate with [5][6][7][8][9][10]29]. The network topology of an ad hoc network changes frequently and unpredictable, so scalability and mobility become extremely challenging in the circumstance we mentioned previously. For many multimedia applications, however, it is desired that an inter-working functionality between the protocols in the ad hoc network and the IP-based Internet. Ad hoc networks should be adapted to deploy rapidly and freely communicating with the traditional mobile wireless networking systems and it does not need the pre-existing network infrastructures [11][12][13][14].However, the broadcast storm becomes a very serious problem for ad hoc networks to migrate into the overlay networks for the application of group communications. The main concept of virtual subnet technology is the capability to group users into broadcast domains, which divides a network into logic, instead of physical, segments and reduces the traffic overhead. The network switch was invented to assist networks to improve this situation. The switch network permits users to be combined into as a virtual subnet. In the router-based network devices are recognized by their physical location in the network. The network-layer address is used to inform the router the physical segment where the data must be sent. A virtual subnet behaves like an ordinary network, but connected devices do not have to be physically connected to the same segment. The virtual subnet allows a flexible mechanism; simply grouping physical ports together, or can comb...

The aim of this paper is to introduce an approach to providing connectivity on trains connecting to the wider Internet via heterogeneous networks and prioritize traffic according to service classes. In an effort to understand the characteristics of a rail network, studies on real life train demonstrations and implementations are briefly discussed. Experiments using the Ns-2 simulator to measure the performance of voice traffic with priority mechanisms are also presented.
