IoV is the latest application of VANET and alliance Internet IoT. With rapid progress in technology, people are searching for a traffic environment where they would have maximum collaboration with their surroundings which comprise other vehicles. It has become necessity to find such we less congestion, minimum chances vehicular collision, communication delay, fewer errors, greater message deliv...

Mobile ad hoc networks (MANETs) are highly vulnerable to both link and node failures due to nodal mobility. The routing resilience against link and/or node failures needs to be enhanced to avoid the degradation of network performance. This can be achieved by multipath routing which uses multiple alternative paths to route the messages via multiple disjoint paths and result in increased bandwidt...

Packet loss is a major issue in Wireless Sensor Network (WSN) data transmission which is caused by malicious packet dropping and link error. In conventional methods, the malicious dropping may result in a packet loss rate that is comparable to normal channel losses, the stochastic processes that characterizes the two phenomena exhibited in different correlation which would affect the network pe...

In MANETs, routing protocols are needed to ensure reliable communications between nodes. They are classified in three categories according to how they establish the routes between any two distanced nodes. There are reactive, proactive or hybrid protocols. The OLSR (Optimized Link State Routing) belongs to the proactive category in which the relays are used to reduce the number of retransmitter ...

Mobile Ad hoc networks (MANET) allow a set of wireless hosts to exchange information without any special infrastructure. Limited battery power is one of the most important issues in mobile ad hoc network as the mobile nodes operate in limited battery power. Also there occurs a problem of broken links due to the lack of energy which cause disorder in network system. Such problem occurs due to th...

To support QoS routing, accurate state information (such as energy level and queue length) should be available and manageable. But due to bandwidth constraints, communication costs, high loss rate and the dynamic topology of MANETs, getting and keeping up-to-date state information is a very complex task, if at all feasible. In this work, we use Optimized Link State Routing (OLSR) as the underly...

In this research, we investigate the adaptive rate control scheme in the IEEE 802.11 ad-hoc network, and evaluate the performance with ad-hoc on-demand distance vector (AODV) and optimized link state routing (OLSR) in fading environments. The proactive routing protocol such as OLSR constructs all routes between nodes, and changes the route in response to link status. In the fading environment, ...

In this paper, we describe the Optimized Link State Routing Protocol (OLSR) [1] for Mobile Ad-hoc NETworks (MANETs) and the evaluation of this protocol through experiments and simulations. In particular, we emphasize the practical tests and intensive simulations, which have been used in guiding and evaluating the design of the protocol, and which have been a key to identifying both problems and...

The network layer of ad hoc networks is prone to attacks. Insertion of false routing information is inherently easy unless the routing messages are authenticated. Hence, protection of the routing protocol is a prerequisite for a reliable network service. The wireless broadcast media calls for bandwidth e¢ cient solutions. This paper proposes a hybrid protection scheme for the ad hoc Optimized L...

Recently, MANET has been gaining the popularity because of its ease of implementation. One of the major elements in MANET is routing protocol, which consists of two main protocols: proactive and reactive routing protocols. In this work, we focus on proactive protocol called OLSR (Optimize Link State Routing Protocol), where the routes are always maintained by interchanging control overhead, nam...
