Optimized Link State Routing protocol (OLSR) is one promising routing protocol for mobile ad hoc networks. It recently reached the RFC step and is still under improvement before becoming a standard. Since its first design, OLSR has been associated with the Multipoint Relay (MPR) protocol to reduce the flooding of OLSR topological messages. Many papers has been written on possible promising solu...

Many of the threats (security, energy, bandwidth and routing problems) facing mobile networks. All these threats are related to high mobility nodes. It is here that our work gives great importance to mobility. This work consists of two parts: The first part is to propose a new way to measure the mobility of nodes, one way is based on two principles: the number of nodes incoming and outgoing fro...

One of the best mobility metrics is the Link Duration (LD) that presents how long two nodes are connected. OLSR is one of the most popular ad-hoc routing protocols. Multipoint Relays (MPR) is used by OLSR for controlled flooding. In this paper, we introduce a new approach to select a MPR in OLSR by using the simplest modification and no additional packet header. This approach introduces the ide...

In this paper we have discussed and evaluated the comparative analysis of performance of OLSR routing protocol in two different networks with different number of users to find out with which network OLSR shows better performance. We are using OPNET simulator tool for the simulation of networks. Few performance metrics like Delay, throughput, end to end delay, MPR calculations, OLSR performance ...

Optimized Link State Routing (OLSR) is a standard proactive routing protocol for Mobile Ad-hoc NETworks (MANETs). In this paper, we use a zero-order Sugeno Fuzzy Logic System (FLS) for adjusting the willingness parameter in OLSR protocol. Decisions made at each mobile node by the FLS take into account its remaining energy and its expected residual lifetime. Simulation study revealed that the pr...

Recent developments in the field of wireless networks lead to the development of short-lived networks known as Mobile Ad hoc Networks (MANET). The Routing protocols in MANET are classified into three categories viz. table driven, on-demand and hybrid protocols. OLSR is one example of table driven routing protocol, which is best suited for dense networks which aims at reducing routing overhead. ...

The standard optimized link state routing (OLSR) introduces an interesting concept, the multipoint relays (MPRs), to mitigate message overhead during the flooding process. This paper propose a new algorithm for MPRs selection to enhance the performance of OLSR using particle swarm optimization sigmoid increasing inertia weight (PSOSIIW). The sigmoid increasing inertia weight has significance im...

In this paper, a proposal for OLSR protocol based upon Boltzmann learning algorithm is made. The main focus is to tune OLSR by using Boltzmann learning algorithm. The proposed work deals with the standardized OLSR routing protocol, to make it more reliable, more energy efficient and more adaptable to the rapidly changing network topology and infrastructure. This article therefore provides a sim...
