In this paper we address the problem of nodes localization in wireless heterogeneous networks, focussing particularly on anchor selection methods to estimate position. The Optimized Link State Routing protocol (OLSR) [1] uses special nodes called Multipoint Relay (MPR) nodes to broadcast control messages within the network. We propose a novel approach based on using these Multipoint Relay (MPR)...

Vehicular ad hoc networks (VANETs) are essential components of a smart city environment owing to some safety-enhancing applications. The use VANETs extends from safety applications such as accident warning and collision avoidance entertainment streaming video or comfort parking spot identification. Besides, these require interconnecting, for example, by enabling vehicles communicate with other ...

In this paper, we examine security issues related to proactive routing protocols for MANETs. Specifically, we investigate security properties of the Optimized Link-State Routing Protocol one example of a proactive routing protocol for MANETs. We investigate the possible attacks against the integrity of the network routing infrastructure, and present techniques for countering a variety of such a...

A MANET is a multi-hop ad-hoc wireless network where nodes can move arbitrary in the topology. The network has no given infrastructure and can be set up quickly in any environment. The Optimized Link State Routing(OLSR) protocol is a route management protocol for such mobile ad hoc networks. This study presents the work of implementing the OLSR routing protocol. The implementation is done in a ...

This paper lays down a proposal of protocol named DREAM_OLSR. The protocol has been developed so as to effect current OLSR (RFC 3626) [4] protocol. The protocol establishes an optimized solution hence the name has been manipulated from Open Link State Routing to DREAM Optimized Link State Routing. DREAM specifies Distance Routing Effective Algorithm for Mobility wherein it implements the Distan...

Self-organized networking is foreseen as an important component in the Internet’s near-future architecture. An essential challenge concerning the integration of this new component is the accomplishment of scalable and efficient ad hoc routing. This report proposes a new solution in this space, DHT-OLSR, based on OLSR enhanced with dynamic clustering and distributed hash table (DHT) routing. We ...

The Optimized Link State Routing Protocol is a popular proactive routing protocol used in wireless mesh networks. However, like many protocols, OLSR can suffer from inefficiencies and suboptimal performance certain network conditions. To address these issues, researchers have proposed using reinforcement learning algorithms to improve the decisions made by OLSR. This paper explores use of three...
