Mobile Opportunistic Networks (OppNets) are infrastructure-less networks consisting of wireless mobile nodes and have been a focus of research for years. OppNets can be scaled up to support rapid growth of wireless devices and technologies, especially smartphones and tablets. Mobile Ad Hoc Networks (MANETs), one of OppNets technologies, have a high potential to be used for facilitating an extension for the Internet and a backup communication platform in disaster situation. However, a connection disruption due to node mobility and unreliable wireless links is possible to trigger a flooding operation of route repair process. This results in transmission delay and packet loss. The flooding of routing packets is an expensive operation cost in MANETs which affects network reliability and wastes limited resources such as network bandwidth and node energy. These are obstacles to practical implementation of MANETs in real-world environment. In this paper, we propose Low Overhead Localized Flooding (LOLF), an efficient overhead reduction routing extension based on Query Localization (QL) routing protocol. The purpose of this work is to control the propagation of routing packets in the route discovery and route repair mechanisms while incurring only a small increase in the size of control information in the packet. Simulation results from extensive experiments show that our proposed method can reduce overall routing overhead, energy consumption, and end-to-end delay without sacrificing the packet delivery ratio compared to existing protocols.

Mobile Ad-hoc NETworks (MANETs) are defined as a collection of mobile nodes that cooperate in order to operate. Nodes in MANETs should build and maintain routes in order to communicate. A routing algorithm is used to manage these routes. MANETs have dynamic topology because of node mobility. The probability of route failure increases when intermediate nodes have higher mobility. This study will propose a routing protocol that depends on the failure history of the nodes from which the route will constructed. The proposed protocol will be implemented over the existing Ad hoc On-Demand Distance Vector (AODV) routing protocol. It is expected that the proposed protocol will improve the packet delivery ratio in the network.

As mobile computing gains popularity, the need for ad hoc routing also continues to grow. In mobile ad hoc networks, the mobility of nodes and error prone nature of the wireless medium pose many challenges, including frequent route changes and packet losses. Such problems increase the packet delays and decrease the throughput. To meet with the dynamic queuing behaviour of Ad hoc networks, to provide QoS and hence to improve the performance, a scheduler can be used. This chapter presents a novel fuzzy based priority scheduler for mobile ad-hoc networks, to determine the priority of the packets. The performance of this scheduler is studied using GloMoSim and evaluated in terms of quantitative metrics such as packet delivery ratio, average end-to-end delay and throughput.

Routing Optimization in mobile ad hoc networks is an ever-demanding task. Mobile ad hoc networks are highly dynamic topology natured and hence several routing protocols meet the challenge of link quality, delay and energy conscious routing. This paper proposes a link quality, delay and energy conscious routing approach based on ant colony optimization. Based on the estimated link quality, delay and residual energy of the nearby nodes, Adaptive node stability (ANS) mechanism is mathematically modeled to make the routing strategy. LQDEARP selects the efficient node based on the ANS mechanism and sends the data packets through that node. Simulation results proved that LQDEARP reduces delay and energy consumption and increases packet delivery ratio than that of the AODV and DECRP protocol.

Mobile ad hoc networks (MANETs) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. The Efficient routing protocols can provide significant benefits to mobile ad hoc networks, in terms of both performance and reliability. Many routing protocols for such networks have been proposed so far. The main method for evaluating the performance of MANETs is simulation. The Network Simulator is a discrete event driven simulator. The goal of ns-2 is to support networking ,research, and education. In this paper we create a new Routing Protocol called My Router step by step in Ns-2.Then we evaluate its performance based on several parameters such as Packet Delivery Ratio , End to End Delay etc and compare it with MANET routing protocol OLSR .

Mobile communication networks have become an integral part of our society, significantly enhancing communication capabilities. Mobile ad hoc networks (MANETs) extend this capability to any time/anywhere communication, providing connectivity without the need of an underlying infrastructure. The new coming realm of mobile ad hoc networks is first investigated, focusing on research problems related to the design and development of routing protocols, both from a formal and technical point of view. Then link stability in a high mobility environment is examined, and a route discovery mechanism is analyzed, together with a practical implementation of a routing protocol in ad hoc multi-rate environments which privileges link stability instead of traditional speed and minimum distance approaches.
