Abstract-In mobile ad hoc networks, solving the standard problems encountered in fixed networks can be challenging because of the unpredictable motion of mobile nodes. Due to the lack of a fixed infrastructure to serve as the backbone of the network, it is difficult to manage nodes' locations and ensure stable node performance. In this paper, we introduce an extension of an algorithm, Multi-path Intelligent Virtual Mobile Node (MIVMN) Abstraction, which effectively processes the unpredictable motion and availability of mobile nodes in MANETs. Earlier work has applied an abstract node, or virtual mobile node, that consists of a set of real nodes traveling on a predetermined path, or virtual path, which causes unavoidable failure when all the nodes that are emulating the virtual mobile node leave its region. The objective of this paper is to increase the message delivery ratio and decrease the fail ratio of the virtual mobile nodes. In order to achieve this, we allow the messages to switch between multiple Hamiltonian circles. Through simulation results we show that the MIVMN abstraction successfully meets our goals.

SUMMARYNext-generation ad hoc networks need to be able to handle high mobility in order to support a wide range of emerging applications such as vehicular networks. Maintaining communication links of an established communication path that extends between source and destination nodes is a significant challenge in mobile ad hoc networks due to the movement of the mobile nodes. In particular, such communication links are often broken under a high mobility environment. Although a new communication route can be established when a break in the communication path occurs, repeatedly reestablishing new routes incurs delay and substantial overhead. To address this limitation, we introduce the Virtual Router abstraction in this paper. A virtual router is a dynamically created logical router that is associated with a particular geographical area. Its routing functionality is provided by the physical nodes (i.e. mobile devices) currently within the geographical region served by the virtual router. These physical nodes take turns in forwarding data packets for the virtual router. In this environment, data packets are transmitted from a source node to a destination node over a series of virtual routers. Since virtual routers do not move, this scheme is much less susceptible to node mobility. We give simulation results to demonstrate the effectiveness of this technique in handling high mobility. They show that the Virtual Router approach can achieve several times better performance than the traditional approach based on physical routers (i.e. relay nodes).
