Temporary Parallel Route Recovery for Frequent Link Failure in VANET

01 Jan 2012-pp 369-374
Abstract: VANET is an upcoming technology to establish communication between the vehicles while travelling, which provides internet connectivity resulting in increased road safety, giving important alerts and accessing comforts while travelling. The VANET technology integrates WLAN, Cellular and Adhoc networks to achieve the continuous connectivity between the vehicles. Vehicle Ad-hoc Networks (VANETs) are systems that allow vehicles to communicate with each other. Wireless device can send information to nearby vehicles, and messages can be routed from one vehicle to another, so that the information can be spread throughout the city. In network there is a very frequent link failure due to high mobility of nodes from available network region. So this frequent link failure causes packets to not reach respective destination. The mechanism proposed here establishes a kind of parallel route discovery for real time application for packets to be delivered at destination by minimizing losses. The main goal is to establish parallel routes during link failures for real time application scenarios to deliver the data safely to destination. The parallel route recovery establishes temporary parallel path between the nodes when there is link failure. The node before the failure link buffers the packets, after establishing new parallel path it then forwards the buffered packets to the destination through newly established path.

Abstract: Mobile edge computing (MEC) allows the use of its services with low latency, location awareness and mobility support to make up for the disadvantages of cloud computing. But an overloaded MEC system or any MEC system failure significantly degrades quality of experience (QoE) and negates the advantages of MEC. In this paper, we propose two different recovery schemes for overloaded or broken MEC. One recovery scheme is where an overloaded MEC offloads its work to available neighboring MECs within transfer range. The other recovery scheme is for situations when there is no available neighboring MEC within transfer range. The second scheme accesses user devices of a neighboring MEC adjacent to the overloaded MEC as ad-hoc relay nodes in order to bridge the transfer disconnect between two MECs. Numerical experiments demonstrated the performance and verified the possibility of the proposed schemes, providing insightful results for potential future research. Fail-safe mobile-edge computing system is proposed.The system uses multihop wireless network.The system allows multi destination data transfer for mobile users to relay.

Abstract: It is difficult for delay tolerant Mobile Ad-Hoc Networks MANETs to render the end-to-end paths from source to the destination where there is no proper connectivity. Opportunistic routing overcomes the deficiencies of conventional MANET routing, and the proposed algorithm works based on quadrant-based look-ahead approach, which is highly efficient in managing the traffic uniformly, conserving energy, and increasing the lifetime of nodes as well as improving the route network stability. The proposed method aimed at reducing the amount of time that packet spends in the buffers. Simulation studies reveal that the proposed novel routing approach outperforms the existing methods.

Abstract: VANET technology integrates wireless cellular and ad hoc for seamless connectivity between vehicles. Vehicle ad-hoc networks (VANETs) are systems that allow vehicles to communicate with each other. Wireless-vice can send information to nearby vehicles, and messages can be sent from one vehicle to another, so that the information can be spread throughout the city. In the network, there is a link failure very common due to the high mobility of nodes in the network region available. So what makes frequent link failure that packets do not reach the respective destinations. The mechanism proposed here establishes a kind of route discovery packet parallel to the real time application to be delivered to the destination, while minimizing losses. The main objective is to establish parallel paths during link failures scenarios for real-time applications to provide data to their destination safely. Recovery road parallel fixed temporary parallel path between nodes when link failure. The node before the link failure packet buffers, after setting the new parallel paths before the packets stored in the buffer via the destination newly created path.

Abstract: Vehicular Ad-hoc Network (VANET) is an upcoming technology for communication between vehicles during the trip, which provides Internet connectivity resulting in safer roads giving access important alerts and comfort during the slip. VANET technology integrates wireless cellular and ad hoc for seamless connectivity between vehicles. VANETs are organizations that allow vehicles to communicate with each other. Wireless-vice can send data to nearby vehicles, and messages can be transported from one vehicle to another, so that the information can be broadcast throughout the metropolis. In the network, link failure is very common due to the high mobility of clients. Frequent link failure occurs as packets do not arrive at the respective goals. The mechanism proposed here establishes a form of route discovery packet parallel to the real time application to be extradited to the destination, while minimizing losses. The primary aim is to establish parallel paths during link failure scenarios for real-time applications to provide information to their destination safely. During link failures, the recovery road is parallel to the fixed temporary parallel path between the nodes. The node before the link failure packet buffers, after setting the new parallel paths before the packets stored in the buffer via the destination newly created path.

Abstract: The Ad hoc On-Demand Distance Vector (AODV) routing protocol is intended for use by mobile nodes in an ad hoc network. It offers quick adaptation to dynamic link conditions, low processing and memory overhead, low network utilization, and determines unicast routes to destinations within the ad hoc network. It uses destination sequence numbers to ensure loop freedom at all times (even in the face of anomalous delivery of routing control messages), avoiding problems (such as "counting to infinity") associated with classical distance vector protocols.

Abstract: An ad-hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure. We present Ad-hoc On Demand Distance Vector Routing (AODV), a novel algorithm for the operation of such ad-hoc networks. Each mobile host operates as a specialized router, and routes are obtained as needed (i.e., on-demand) with little or no reliance on periodic advertisements. Our new routing algorithm is quite suitable for a dynamic self starting network, as required by users wishing to utilize ad-hoc networks. AODV provides loop-free routes even while repairing broken links. Because the protocol does not require global periodic routing advertisements, the demand on the overall bandwidth available to the mobile nodes is substantially less than in those protocols that do necessitate such advertisements. Nevertheless we can still maintain most of the advantages of basic distance vector routing mechanisms. We show that our algorithm scales to large populations of mobile nodes wishing to form ad-hoc networks. We also include an evaluation methodology and simulation results to verify the operation of our algorithm.

Abstract: VANET is new generation of ad hoc networks that implement between vehicles on a road. Because of high mobility, routing in VANET has more problems than MANET. Thereby, in this paper we propose a modification on AODV as MANET routing protocol to make it adaptive for VANET. When a node is mobile, it has three mobility parameters: position, direction and speed. In our method, we have used direction as most important parameter to select next hop during a route discovery phase. With respect to mobility model, if nodes has same direction with source and/or destination nodes, our solution might selects them as a next hop. Position is another parameter that we used for next hop selection.

Abstract: To avoid frequent route discovery, various multipath routing protocol has been proposed based on the existing single path routing protocol in ad hoc networks. Ad hoc on-demand multipath distance vector (AOMDV) is one of extensions to the well-studied ad hoc on distance vector (AODV). In this paper an optimized AOMDV (OAOMDV) is presented to solve the "route cutoff" problem in AOMDV. The proposed protocol adds a new scheme into AOMDV and simulation results show the performance improvement

Abstract: Vehicular ad hoc networks (VANETs) using WLAN technology have recently received considerable attention. One of the critical research challenges consists of the design of scalable routing algorithms that are robust to frequent path breakage caused by high mobility of vehicles. In this paper, we propose a multipath routing protocol for VANET named Fast Restoration On-demand Multipath Routing (FROMR). Different from previous researches which emphasize path disjointness, FROMR focuses on rapidly building an alternate path if the original route is broken. In order to reduce the amount of control messages as well as increase the path robustness, FROMR partitions the geographic region into squares of equal-size called grids. Inside each grid, a vehicle which is expected to stay for the longest duration is selected as the grid leader. Only grid leaders are responsible for route discovery, maintenance and restoration. Experimental results show that the proposed FROMR protocols outperform the popular AODV protocol in terms of packet delivery ratio, throughput, route lifetime, and control overhead.
