Optimized Link State Routing

In this paper, we evaluate the performance of Optimized Link State Routing (OLSR) protocol by experimental and simulation results. The experiments are carried out by using our implemented testbed and the simulations by using ns-2 simulator. We also designed and implemented a new interface for the ad-hoc network testbed in order to make more easier the experiments. The comparison between experimental and simulation results shows that for the same parameters set, in the simulation we did not notice any packet loss. On the other hand, in the experiments we experienced packet loss because of the environment effects and traffic interference.

Optimized Link State Routing

Vehicle Ad Hoc network (VANET) has grown fast in recent years. The routing protocol is one of the key technologies in VANET. Due to the particularity of VANET networks, the implementation and validation of all the protocols in realistic scenes are not possible. In this paper, we use the network simulation software OPNET to simulate the network models of VANET in different urban scenarios. We assessed the performance of Dynamic Source Routing (DSR) and Optimized Link State Routing (OLSR) protocols. Then we propose a new method by deploying the roadside equipment with Mobile IP. The results show that the performance is improved compared with the existing schemes.

Selection Of

Multi Point Relays (MPRs) are those nodes that are calculated and determined by the Optimized Link State Routing protocol (OLSR) in order to minimize and avoid overload inside the Mobile Ad hoc Network (MANET). In this paper, we will present a synthetic study of many techniques and methods for calculating and selecting the MPR nodes using a set of criteria namely energy, mobility, bandwidth, the quality of links, etc. The result of this study shows that most techniques consider a limited number of metrics for selecting the MPR nodes and therefore they are insufficient to allow the OLSR protocol to be quite complete and efficient because several metrics can occur at the same time in the real execution environment.

Optimized Link State Routing

In an Optimized Link State Routing (OLSR)-based mobile wireless network, optimizing the flooding of broadcast messages is a challenging task due to node's mobility and bandwidth resource consumption. To complement existing solutions to this problem, the Multi-Point Relays (MPR) selection has recently been advocated as a promising technique that has an additional feature of reducing the number of redundant re-transmission occurring in the network. This paper continuous on the investigation of an existing MPR-based solution, arguing that by considering a cost factor as an additional decision parameter in selecting the MPR nodes, the enhanced MPR selection algorithm leads to less packet loss in the network. Simulation experiments are presented to validate the stated goal, using the average packet loss ratio as the performance metric.

Optimized Link State Routing

This paper describes the integration of mobile IP in mobile ad hoc network (MIPMANET) in large area network (LAN) between 8 nodes, where latency, delay, throughput is considered for the quality of service (QoS) consideration. For the best result of MIPMANET, the Dynamic Source Routing Protocol (DSR) and Optimized Link State Routing Protocol (OLSR) are considered. Although MANET has other routing protocols, the DSR performs better in MIPMANET integration in NS2. Mobile IP is applied for doing the dynamic topology to static topology as the nodes are flexible in an ad-hoc network. Simulation result suggests that the MANET performs better in DSR with MIP as the amount of packet drop is low and throughput is high

Optimized Link State Routing

Abstract In the last recent years, the number of wireless devices has been growing and the security challenges increases too. Mobile Ad hoc Network (MANET) considers as a part of wireless network that connects mobile devices by using wireless channels without infrastructure. MANET use specific protocols to ensure the connectivity and exchange data between the source and destination. Optimized Link State Routing Protocol (OLSR) is a table-driven protocol that keep the route to all destination at any times, unfortunately it can be affected by many active routing attacks that reduce its performance by dropping the exchange packets or stopping the forward of data. In this paper we present a new approach to detect any active routing attacks by using the concept of Shapiro-Wilk test. Our method of detection is easy to implement and does not require any modification in the standard version of OLSR routing protocol as we will demonstrate by NS-3 simulations the detection of Black hole, Worm hole and Node isolation attacks that consider as most known attacks in MANET. A real experience is done by creating a small ad hoc network that connect six wireless devices by using OLSR protocol and finally we detect the presence of an active routing attack by applying our proposed method.

A wireless ad hoc network is a decentralized kind of wireless network. It is a kind of temporary Computer-to-Computer connection. It is a spontaneous network which includes mobile ad-hoc network (MANET), vehicular ad-hoc network (VANET) and Flying ad-hoc network (FANET). Mobile Ad Hoc Network (MANET) is a temporary network that can be dynamically formed to exchange information by wireless nodes or routers which may be mobile. A VANET is a sub form of MANET. It is an technology that uses vehicles as nodes in a network to make a mobile network. FANET is an ad-hoc network of flying nodes. They can fly independently or can be operated distantly. In this research paper Fuzzy based control approaches in wireless network detects & avoids congestion by developing the ad-hoc fuzzy rules as well as membership functions.In this concept, two parameters have been used as: a) Channel load b) The size of queue within intermediate nodes. These parameters constitute the input to Fuzzy logic controller. The output of Fuzzy logic control (sending rate) derives from the conjunction with Fuzzy Rules Base. The parameter used input channel load, queue length which are produce the sending rate output in fuzzy logic. This fuzzy value has been used to compare the MANET, FANET and VANET in terms of the parameters Throughput, packet loss ratio, end to end delay. The simulation results reveal that usage of Qual Net 6.1 simulator has reduced packet-loss in MANET with comparing of VANET and FANET.
