Survey on network mobility support <s> VII.B. Route optimization with the participation of the nodes within the network <s> In this paper, we describe the Optimized Route Cache Management Protocol (ORC) as a network mobility protocol and evaluated it through experiments on a prototype implementation. ORC provides mobility transparency to a network regardless of network movements. Mobile network is a network that moves entirely. Typical examples for a mobile network are personal area networks (PAN) and networks inside vehicles. ORC is based on mobile IPv6 and is combined with the Internet routing mechanisms for network mobility management. ORC assigns a unique unchanging subnet prefix to a mobile network and notifies and maintains a mobile network's route called binding route (BR). A BR is an association between the prefix of the mobile network and a current available address known as care-of address in mobile IPv6. ORC allows interior gateway protocol (IGP) routers named ORC routers to cache a BR. ORC routers intercept packets destined to the mobile network and route them to the mobile network according to the BR. The BR must be updated as soon as the mobile network changes the care-of address by its topological position, employing constant BR exchange to ORC routers and temporary BR exchange to dynamically discovered ORC routers. Based on the experimental results, ORC is confirmed to provide network mobility and optimal communication in terms of route optimization. The evaluation shows that route optimization is required for network mobility to improve communication performance. <s> BIB001 </s> Survey on network mobility support <s> VII.B. Route optimization with the participation of the nodes within the network <s> This paper presents the mechanism which allows mobile nodes in mobile network to perform route optimization. The mechanism is based on the prefix delegation protocol which is an address autoconfiguration technique on router. Mobile router gets a prefix from an access router using prefix delegation protocol and advertises the delegated prefix to its subnet. Each mobile node makes its care-of address from the prefix and performs binding update. It allows the mobile nodes to communicate with correspondent nodes directly by pass ingress filtering. In this paper, we define a new IPv6 neighbor discovery option to advertise the delegated prefix and extend a mobile node operation to process the new option. <s> BIB002 </s> Survey on network mobility support <s> VII.B. Route optimization with the participation of the nodes within the network <s> More and more people want to access the Internet and virtual private networks from anywhere at anytime. This has given rise to providing connectivity capabilities to commuters of public transportation systems. Internet access from moving vehicles has necessitated an architecture which relies upon a special entity, namely a mobile router to support the mobility of the entire network. This paper presents an optimal routing architecture for devices accessing the Internet through a mobile router deployed in such a mobile network. Our scheme takes into consideration all entities involved in a network mobility scenario and attempts to diffuse the mobility management load without burdening a single entity of the architecture. Our architecture has three main benefits. Firstly, it provides mechanisms for any type of mobile network node present in the network - mobility aware or mobility unaware - to communicate using optimal routes with their correspondent nodes. Secondly added functionality to the MIPv6 operation is neither required at the correspondent nodes nor at the mobile network nodes. Thirdly, our architecture reduces and diffuses the processing burden at the mobile routers and their home agents. <s> BIB003
The solutions BIB001 ,  , BIB002 ,  ,  , BIB003 propose route optimization solutions with the participation of nodes within the network. The generic idea of these schemes requires the MR when in a foreign network to obtain a care-of prefix (rather than just a single address), and readvertise this location dependent prefix into the mobile network. The mobile network nodes can then auto configure a location specific care-of address, which when communicated back to the correspondent nodes leads to optimal routing, as per MIPv6. The solution proposed by Jeong et al  incorporates a method in order to route optimize as well as a method to allow mobile nodes to optimize their DNS name resolutions. This solution is only aimed at mobile nodes within the network. Ohinishi et al  has proposed a route optimization method based on HMIPv6  technology and it is evident in this scheme added functionality is required at the correspondent nodes and also from the nodes within the network. Perera et al BIB003 have proposed an optimal routing architecture for network mobility named as OptiNets, which caters for any type of node present within the mobile network. The main objective of the OptiNets architecture is to enable optimal routing for mobile nodes by exploiting the desirable features of the MIPv6 and the NEMO Basic Support protocol. By introducing a lightweight protocol between the Mobile Routers and their Home Agents benefits of aggregated routing is preserved as per NEMO protocol. This protocol named as Distributed Home Agent Protocol (DHAP) authorizes the Mobile Router to act as the Home Agent for the Local Mobile Nodes. This solution does not require any added functionality to MIPv6 Correspondent Nodes nor to any node within the mobile network when enabling optimal routing for all nodes in the mobile network.
