Delay Aware Routing Protocol Using Optimized AODV with BBO for MPLSMANET

Abstract

Mobile Ad Hoc Network (MANET) is a wireless network that does not have any fixed structure. MANET is a collection of independent mobile nodes that can communicate with each other through radio waves. In conventional Internet Protocol (IP) forwarding, each router creates forwarding decision on the basis of IP header information. The router has to analyse the packet and routing table at each hop to take the decision for data transmission. Since, inappropriate decisions in data transmission causes delay in packet delivery. This can be overcome with the help of a special feature of Multiprotocol Label Switching (MPLS) called Label switching. MPLS is a switching mechanism that plays a good role in routing, switching and forwarding using small labels. The MPLS is integrated into MANET to improve network performance. In this paper, an effective routing strategy is introduced to reduce the transmission time between routers during the data transmission. Here the Ad Hoc On-Demand Distance Vector (AODV) with Biogeography Based Optimization (BBO) based routing method is used to identify the optimal route among the routers of the MPLS based MANET. The proposed methodology is named as AODV-BBO. Three different objective functions are considered in this routing strategy viz., residual energy, distance and number of hops. Moreover, the rerouting is performed when the node or link failure occurs in the network. This rerouting is used to overcome the packet drop through the MPLS based MANET. The performance of AODV-BBO methodology is analysed in terms of percentage of alive nodes, dead nodes, energy consumption, end to end delay and bandwidth. The performance of the AODV-BBO methodology is compared with two existing methods P2R2 and PS-ROGR. Result showed that, the energy consumption of the AODV-BBO methodology with 400 nodes is 536.52 J, which is less compared to the PS-ROGR method.

Improved Routing Protocols: A First Step Towards Quality of Service in Mobile Ad-hoc Networks

“…The AODV-BBO routing technique suggested by Jayaramu and Banga [34] considered three separate goal functions in the routing strategy: residual energy, distance, and the number of hops. Furthermore, rerouting was done in the event of a network node or connection failure.…”

Learning Automata-Based AODV to Improve V2V Communication in A Dynamic Traffic Simulation

“…LA-AODV protocol ensures accurate car parts estimation and informed routing decisions in vehicular communication networks by predicting vehicles' current and future positions based on their speed and relative position and determining actual positions using velocity and acceleration parameters, as stated in Eq. (2).…”

“…The conventional AODV protocol suffers from excessive information flow and reduced inter-vehicle communication responsiveness in VANETs [1,2]. The drawback of AODV is primarily due to suboptimal relay node selection caused by dynamic vehicle quantity fluctuations on busy roads [3].…”

Comparing the Performance of Ospf and Ospf-MPLS Routing Protocol in Forwarding TCP and Udp Packet

“…Dalam pengukuran dynamic routing OSPF dengan menggunakan Quality of Service (QoS), teknologi Multiprotocol Label Switching (MPLS) menjadi solusi yang efisien. MPLS menggunakan label untuk mengarahkan data melalui jaringan dengan lebih cepat dan efisien, mengurangi beban pemrosesan pada router dan mendukung QoS [16]. MPLS membantu meningkatkan kualitas layanan secara keseluruhan dalam jaringan komputer, mengoptimalkan kinerja, dan mengatasi masalah trafik yang sering dihadapi.…”
