New Multipath OLSR Protocol Version for Heterogeneous Ad Hoc Networks

Abstract

From a basic refrigerator to a self-driving car, emerging technologies are increasingly involving various facets of our daily lives. These bring together many regularly used devices, each with its own characteristics, to communicate and collaborate within the same system. Computer network experts regard this so-called structure as a heterogeneous network made up of several connected objects that do not speak the same language. Communication is therefore ensured by additional types of nodes, such as gateways or converters. In this case, we can detect an increased complexity and a decreased level of security. And thus, the need to adopt a common slang for these kinds of networks has been brought to life. In this work, we compare two different routing protocols: optimized link-state routing (OLSR) and the multipath heterogeneous ad hoc network OLSR (MHAR-OLSR). The latter is an OLSR extension with new functionalities: nodes identification, paths calculation, paths classification, and paths choice that we designed for heterogeneous ad hoc networks composed of MANET, VANET, and FANET devices; it ensures direct communication between these diverse components. We verify and explain all the elements of our solution using colored Petri nets. We also present a global evaluation of Packet Delivery Ratio (PDR), End-To-End Delay, and energy consumption as QoS measures with different numbers of nodes in a heterogeneous scenario. To do this, we use NS-3 and BonnMotion as a tool-set of simulation. Experimental results show improvement in performance when compared to the classical routing protocol.

Estimation of the Achievable Performance of Mobile Ad Hoc Networks with Optimal Link State Routing

“…The results of calculations of MANET parameters using the expressions obtained in the paper are confirmed with the modeling results given in [31,38,39].…”

“…For example, an improved OCI-OLSR protocol (Optimized-Control-Interval-Optimized-Link-State-Routing) is proposed in [30], which focuses on better control interval management, enhanced MPR process selection, reducing neighbor hold time, and decreasing flooding. In [31], the multipath heterogenous ad hoc network OLSR (MHAR-OLSR) protocol is described and investigated. MHAR-OLSR is an OLSR extension with new functionalities: nodes' identification, paths' calculation, paths' classification, and paths' choice, designed for heterogeneous ad hoc networks composed of MANET, VANET, and FANET devices.…”

OCI-OLSR: An Optimized Control Interval-Optimized Link State Routing-Based Efficient Routing Mechanism for Ad-Hoc Networks

“…With diverse numbers of nodes in a heterogeneous scenario, assessment is done on QoS dimensions using the simulation toolkits NS-3 and BonnMotion. According to the findings obtained, MHAR-OLSR exhibits far better performance than the traditional routing protocol [18].…”

“…In an investigation done by the authors in their work, they differentiated OLSR along with MHAR-OLSR (multipath heterogeneous ad hoc network) scheme [18]. They invented an expansion to OLSR that incorporates new features such as node identification, pathways calculation, path categorization, and path selection.…”

A new routing method based on ant colony optimization in vehicular ad-hoc network

“…In (16), the authors proposed the extension of OLSR protocol in the heterogeneous ad hoc network (composed of MANET, VANET and FANET devices) with multiple paths (MHAR OLSR). This new protocol enables new functionalities: node identification, path computation, path classification and path selection.…”
