TL;DR: This work focuses upon routing protocols for ad hoc networks, study and compare the performance of several routing protocols, and a variety of workload and scenarios using a range of mobility, load and size of the ad hoc network were simulated.
Abstract: A mobile ad-hoc network (Manet) is a system of wireless mobile nodes dynamically self-organizing in arbitrary and temporary network topologies. People and vehicles can thus be internetworked in areas without a pre-existing communication infrastructure, or when the use of such infrastructure requires wireless extension. Therefore, such networks are designed to operate in widely varying environments, from military networks to low-power sensor networks and other embedded systems. Frequent topology changes caused by node mobility make routing in ad hoc wireless networks a challenging problem. We focus upon routing protocols for ad hoc networks. We study and compare the performance of several routing protocols. A variety of workload and scenarios using a variety of mobility, load and size of the ad hoc network were simulated.

TL;DR: This paper presents a master/slave cellular-based mobile ad hoc network architecture for multihop multimedia communications based on a new paradigm for solving the problem of cluster-based ad hoc routing when utilizing existing wireless local area network (WLAN) technologies.
Abstract: This paper presents a master/slave cellular-based mobile ad hoc network architecture for multihop multimedia communications. The proposed network is based on a new paradigm for solving the problem of cluster-based ad hoc routing when utilizing existing wireless local area network (WLAN) technologies. The network architecture is a mixture of two different types of networks: infrastructure (master-and-slave) and ad hoc. In this architecture, the participating slave nodes (SNs) in each cluster communicate with each other via their respective master nodes (MNs) in an infrastructure network. In contrast to traditional cellular networks where the base stations are fixed (e.g., interconnected via a wired backbone), in this network the MNs (e.g., base stations) are mobile; thus, interconnection is accomplished dynamically and in an ad hoc manner. For network implementation, the IEEE 802.11 WLAN has been deployed. Since there is no stationary node in this network, all the nodes in a cluster may have to move together as a group. However, in order to allow a mobile node to move to another cluster, which requires changing its point of attachment, a handoff process utilizing Mobile IP version 6 (IPv6) has been considered. For ad hoc routing between the master nodes (i.e., MNs), the Ad hoc On-demand Distance Vector (AODV) Routing protocol has been deployed. In assessing the network performance, field test trials have been carried out to measure the proposed network performance. These measurements include packet loss, delays under various test conditions such as a change of ad hoc route, handoffs, etc.

08 Apr 2011TL;DR: A comparative study proves that AODV, TORA performs well in dense networks than OLSR in terms of packet delivery ratio, and this research paper describes the characteristics of ad hoc routing protocols O LSR, A ODV and TORA based on the performance metrics.
Abstract: Mobile Ad hoc Network (MANET) is a collection of mobile nodes in which the wireless links are frequently broken down due to mobility and dynamic infrastructure. Routing is a significant issue and challenge in ad hoc networks. Many routing protocols have been proposed like OLSR, AODV, DSR, ZRP, and TORA so far to improve the routing performance and reliability. This research paper describes the characteristics of ad hoc routing protocols OLSR, AODV and TORA based on the performance metrics like packet delivery ratio, end-to-end delay, routing overload by increasing number of nodes in the network. This comparative study proves that AODV, TORA performs well in dense networks than OLSR in terms of packet delivery ratio.

TL;DR: Experimental analysis is carried out on AODV, DSDV and OLSR routing protocol for FANET environment using NS2 simulator to improve the performance of adhoc networks.
Abstract: In recent years the capability and role of Mobile Adhoc Networks have rapidly evolved. Their use in emergency, natural disaster, military battle fields and UAVs is getting very popular as a result of cutting edge technologies in networking and communication. Using the concept of MANET new networking paradigms like VANET and FANET have evolved. FANET is comparably new concept of MANET and it has capabilities to tackle with situations where traditional MANET cannot do so. Due to high mobility and fast topology change in FANET, this is highly challengeable for researcher to implement routing in FANETs. Routing protocols play a dominating role in enhancing the performance of adhoc networks. In this paper, experimental analysis is carried out on AODV, DSDV and OLSR routing protocol for FANET environment using NS2 simulator.
