New developments in wireless communication have enabled the use of highly efficient and inexpensive receivers a variety portable applications. Each node mobile network is device that independently organizes its own connection to others manages data transmissions. The adaptability, scalability, cost reduction networks attracted considerable attention. Because are constantly changing, problems wi...

Optimised Link State Routing (OLSR) is a popular protocol for use in MANET networks. In this paper, we investigate the different impacts of tuning refresh interval timers on OLSR performance under various scenarios (varying node density and node speed). Based on the simulation results with NS2, we find that although reducing refresh intervals could improve OLSR’s performance, the intervals for ...

A mobile ad-hoc network (MANET) is an infrastructure less open network of moveable devices which are connected by wireless links. Every node in a MANET is free to move in any direction and will therefore change its links to other devices continuously and unpredictably. Mobile devices can communicate with each other without the use of a predefined infrastructure or centralized administration. In...

As (network) software is such an omnipresent component of contemporary mission-critical systems, formal analysis is required to provide the necessary certification or at least formal assurances for these systems. In this paper we focus on modelling and analysing the Optimised Link State Routing (OLSR) protocol, a distributed, proactive routing protocol. It is recognised as one of the standard a...

This paper presents a novel approach to integrate Wireless Local Area Networks (WLANs) and Mobile Ad-hoc Networks (MANETs) to the Internet Protocol version 6 (IPv6) based Internet. In the proposed network architecture, the mobiles, connected as a MANET, employ the Optimized Link State Routing (OLSR) protocol for routing within the MANET. Gateways are used to connect MANETs to the Internet. This...

In a MANET, the aggressive progress of research is running continuously after the important study of AODV, DSR, TORA and OLSR routing protocols. Many studies and researches are done by using different methods on these routing protocols in manner of performance evaluation. By this study every different method and simulation environment gives the different results, means every applied method give...

In a mobile ad hoc network (MANET), a source node must rely on intermediate nodes to forward its packets along multihop routes to the destination node. Due to the lack of infrastructure in such networks, secure and reliable packet delivery is challenging. The performance of a Mobile Ad hoc Network (MANET) is closely related to the capability of the implemented routing protocol to adapt itself t...

With data transparency and immutability, the blockchain can provide trustless decentralized services for Internet of Things (IoT) applications. However, most blockchain-IoT networks, especially those with a private blockchain, are built on top an infrastructure-based wireless network (i.e., using Wi-Fi access points or cellular base stations). Hence, they still under risk Single-Point-of-Failur...

Mobile Ad-hoc Networks (MANETs) are the one where each node participating has many roles assigned, that is of a receiver, transmitter and router. Hence, energy in abundance is expected to be expended on each role to achieve the normal working. Also, mobility factor of this infrastructure-less administration forces the nodes to confide on battery energy. Battery being a limited entity fails to f...

Energy efficiency is a key issue in wireless ad hoc and sensor networks. In order to maximize network lifetime, several directions have been explored, among them energy efficient routing. In this report, we show how to extend the standardized OLSR routing protocol, in order to make it energy efficient. To take into account residual node energy, the native selection of multipoint relays of OLSR ...
