The concept of VANET (Vehicular Ad hoc Network) is derived from the idea of MANET (Mobile Ad hoc Network), where each vehicle is considered as a mobile node. Localization technique based on the clustering methods is an important issue for both MANET and VANET. To find out the position of a node and also provide the link stability in the ad hoc network is a present research area from the researcher view. Now-a-days a large spectrum of work has already been done in clustering techniques in ad hoc network, especially in VANET. The clustering technique is very much useful for reliable and faster data communication in both the forms of networks. The objective of this paper is to provide an idea about the localization concept related to clustering method based on both GPS and GPS free situations in real world scenario.

Mobile Ad Hoc

A Mobile Ad-Hoc Network (MANET) is a decentralized network of mobile node that are connected to an arbitrary topology via wireless connections. The breakdown of the connecting links between adjacent nodes will probably lead to the loss of the transferred data packets. In this research, we proposed an algorithm for link prediction (LP) to enhance the link break provision of the ad hoc on-demand remote protocol (AODV). The proposed algorithm is called the AODV Link Break Prediction (AODVLBP). The AODVLBP prevents link breaks by the use of a predictive measure of the changing signal. The AODVLBP was evaluated using the network simulator version 2.35 (NS2) and compared with the AODV Link prediction (AODVLP) and the AODV routing protocols. The simulation results reveal the effectiveness of AODVLBP in improving network performance in terms of average end-to-end delay, packet delivery ratio, packet overhead ratio, and packet drop-neighbour break.

Background: Mobile Ad-hoc network is a set of devices which are capable of communicating with each other without the help of any central entity or fixed infrastructure. The absence of fixed access points makes MANET flexible and deployable at the extreme geographical territories. Each device has routing capabilities to facilitate communication among nodes in the network. Objectives: 1) To selects the stable path which has lowest hop count. 2) To use backup path in case of link break up to minimize delay incurred in finding out the alternate path. Method: Dynamic source routing is modified to choose the most stable path and a backup path is cached to save the route discovery time in case of link failure. Results: The modified-DSR based on Link stability and hop count is performing better as compared to DSR most of the time. Conclusion: A modified-DSR is proposed that selects the path using hop count and link stability as parameters. The advantage of modified-DSR is that if a link breaks in between data communication then back up path can be used for carrying out the data transfer. Analysis is done by varying the node density and counting number of packets received .Modified-DSR gives better results for light to moderate network and DSR performs better if the number of nodes increases beyond a certain limit.

Vehicular Ad-hoc Network (VANET) is associate rising autonomous dynamic topology network. It is a unique type of Mobile Ad-hoc Network during which the automobiles amendment their message with each other. VANET turns every automobile in it into a mobile node and use those nodes to make a mobile dynamic community. The aim of VANET is to produce a wi-fi connectivity and numerous programs applications like collision dodging, safety and rising the traffic ratio as designing by the Intelligent Transportation System (ITS). The transport are strained by the sensible traffic surroundings, and currently the simulations are primarily network simulations that cannot simulate the real hint of the object (vehicle). Merely as nodes in VANETS have identical excessive mobility, so there are masses of demanding situation to route the packets to there final destination which need to be addressed by means of existing/offering new solutions for the comparable. Keeping view of above, In this paper, summarize the prevailing VANET routing protocols and classify and evaluate them. Then, listing numerous classic routing algorithms and examine their characteristics and advantages and disadvantages. Eventually, by way of analyzing the reputation of vehicle-installed routing protocols, we tend to illustrate the difficulties and challenges that vehicle-mounted routing protocols can/will encounter within the future.

Mobile Ad hoc Network (MANET) is a dynamic wireless mobile node network, without using network infrastructure such as limited power (because it uses batteries). Mobility of each node that is able to move in all directions, and autonomy of each node in determining its own route to forward the data plan. Therefore, in this study we will see the performance of MANET on IEEE 802.11 g WLAN with a data rate that is different from an AODV routing protocol. This simulation observes changes in data rates ranging from 1, 2.5 Mbps, using WLAN 802.11 g. For parameters used in the data rate starting from 1, 2, 5, Mbps using WLAN 802.11 g obtained the Package Loss value at a data rate of 5 Mbps by 0.98%, the highest value of the highest throughput was generated at a data rate of 1 Mbps of 313,715 bps, and the delay for the data rate of 5 Mbps was 0.0008 second.

Mobile ad hoc Network is infrastructure less wireless network and decentralized way, and then for a large network number of nodes dynamically therefor the connection established between source node to destination node is really challenging. The challenge is interconnecting ad hoc network to the internet seems from the needs to inform ad hoc nodes about available gateways in an extremely challenging scenario while a making a minimum consumption of the source network resources. Then an efficient gateway discovery of an ad hoc network becomes one of the central factors to enable the economic consumption of hybrid ad hoc network in future mobile and wireless network. In mobile ad hoc network have multihop nature of MANET therefore several reachable gateways for mobile node at any period of time. If the mobile node receives gatways advertisement from more than one gateway. It has to determine which gateway to use for connecting to the net. Most existing protocol choose the gateway which is closer in terms of the number of physical hops. This paper has focused on design an efficient and adaptive subnetting hybrid gateway discovery mechanism on the basis of dynamic TTL value adjustment such that congestion and unnecessary overhead is reduced. Selecting the gateway on the basis of one and two parameters will increase the performance and throughput of the network. The main objective of adaptive gateway discovery to determine the optimal TTL value in terms of number of hops to determine the proactive area, nodes outside this area follow the reactive approach. Consequently, for achieving a good trade off between performanceand network operating expense.

VANET (Vehicular Ad-Hoc Network) adalah bentuk khusus dari MANET (Mobile Ad-Hoc Network). VANET (Vehicular Ad-Hoc Network) adalah jaringan yang terdiri dari kumpulan node mobile nirkabel yang berkomunikasi satu sama lain tanpa infrastruktur yang tetap. Pergerakan MN (Mobile Node) pada VANET sangat tinggi dan menyebabkan IP Address pada MN sering berubah. Berdasarkan kondisi jaringan yang berubah, koneksi yang terjadi antara MN menjadi terganggu dan terputus selama beberapa detik. Selain itu, menyebabkan delay yang besar dan throughput yang lebih kecil dengan paket loss tinggi jika di suatu daerah jumlah MN meningkat secara signifikan. Dalam simulasi ini diukur kinerja antara jaringan Mobile IPv6 (MIPv6) dan Hierarchical Mobile IPv6 (HMIPv6) menggunakan agen transport UDP dengan beberapa ukuran paket data CBR. Berdasarkan parameter utama dalam menentukan kualitas jaringan, akan dibandingkan dan diperoleh nilai dari handover latensi, dengan mengukur packet loss, throughput, dan delay. Berdasarkan hasil studi literatur, dapat disimpulkan bahwa kinerja jaringan HMIPv6 lebih baik daripada MIPv6 karena HMIPv6 memiliki paket loss dan delay yang lebih kecil dan throughput yang lebih besar dibandingkan dengan MIPv6.
