Review on Optimization Techniques of OLSR Protocol for VANETs
نویسنده
چکیده
: To maintain the topology information of the entire network OLSR exchange messages from time to time for every presence of mobility and failures. HELLO, Topology Control (TC) and multiple interface declaration (MID) messages are main three types of messages used for performing the core functionality. The objective of this review is to Study the scalability issue in optimized link state routing (OLSR) protocol. In this paper, study of scalability issues in OLSR in Mobile Ad hoc Network (MANET), mobility, traffic and node density are main network conditions that significantly affect performance of routing protocol. Thus the optimal parameter setting of the OLSR, by defining an optimization problem can solve the problem. Keywords— Meta-heuristics, OLSR, Optimization Algorithms, Vehicular ad hoc networks (VANET), Techniques

Optimal Configuration for Urban VANETs Routing using Particle Swarm Optimization
Optimization Link State Routing Protocol (OLSR) is initially designed for ad hoc networks (MANETs). This protocol collects information to build and maintain the route between the source and the destination with minimum cost by periodically exchange Hello and control messages. The aggregate function of communication cost for all nodes computed based on the required performance metrics. The stand...
متن کاملSimulation and Automatic Tuning of OLSR Routing Protocol for VANETs
This paper presents a class of routing protocols for vehicular ad hoc networks (VANETs) called the Optimized link state routing protocol (OLSR). OLSR protocol performs well in networks having changing topology of nodes, as it can adapt in such environments easily and updated routing table is maintained by all nodes all the time. Wide range of improvement is possible by changing only the configu...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
متن کاملOptimizing OLSR Protocol for VANET
Vehicular ad hoc network is a non infrastructure network where each network node not only acts as a host but also acts as a router. The environment is highly dynamic due to mobile nature of nodes. The proper functioning of these networks depends upon a routing protocol that can respond to the rapid changes in the topology. Our interest is focused on the OLSR routing protocol, which uses hello a...
