In this paper, we investigate the benefits of Optimized Link State Routing Protocol used for communication in underground mines. Due to network failures, node and link failures in the past few years an explosive growth in the use of wireless routing protocols for communication needs in the underground environment. Most studies indicate that it is impossible for reliable routing under ground lev...

One of the critical issues in Mobile Ad hoc Network (MANET) is the energy efficiency. The challenge is how to extend the limited lifetime of energy in mobile nodes. We proposed a new approach to minimise the energy consumption called EM-OLSR (Energy Efficiency in MANET by improving OLSR protocol). EM-OLSR is based on the OLSR routing protocol and adds a new energy fairness parameter to the Mult...

Mobile Ad Hoc network is a selfconfiguring infrastructure less network, without centralized infrastructure. Power heterogeneity is common in mobile ad hoc network. In MANET, interference significantly reduces the network performance such as data loss, conflict, retransmission and so on. Interference is one of the problems in research. In this paper, apply a formula to calculate the interference...

: 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...

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...

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, namely HELLO ...

In this paper discusses and evaluates “Optimized Link State Routing Protocol” OLSR routing protocol to better performance. Using OPNET simulator tools for the performance of OLSR routing protocol simulation, create in small network (30 nodes), medium size network (40 nodes) and large network (50 nodes) the complexity of the mobile ad-hoc network. The MPR count,”HELLO”message sent ,routing traff...
