A Bidirectional Backup Routing Protocol for Mobile Ad Hoc Networks

Abstract

In mobile ad hoc networks (MANET), due to rapidly changing network topology, routing break occurs frequently. Ad hoc on-demand distance vector adaptive backup with local repair routing (AODV-ABL) protocol creates and maintains backup routes to the destination node by overhearing data packets to increase the success rate of repairing invalid routes. However, AODV-ABL may lose some backup routes with one hop distance to the destination node, and cannot adjust the primary routes in time to adapt to the dynamic topology. In this paper, based on AODV-ABL, an AODV bidirectional fast adaptive backup local repair (AODV-BFABL) routing protocol for bidirectional traffic load scenarios is proposed, which can maintain the bidirectional routes to the destination and source nodes to reduce route failures. In order to improve the adaptability of AODV-BFABL, the primary routes are merged with the backup routes and the routes are updated when transmitting the data packets. Simulation results show that AODV-BFABL has better packet delivery ratio, end-to-end delay and control overhead than AODV-ABL.

Efficient route selection in ad hoc on-demand distance vector routing

“…The proposed protocol ERS-AODV is compared with other three protocols: M-AODV [14], AODV [5] and AODV-ABL [13]. The average control overhead is improved than the previous protocols; is shown in figure 2.…”

“…The work presented in [12] introduces any cast routing in MANET with dynamic source routing is used to select k-servers based on less congestion, hops number, route expiry time and better stability have contributed to the improvement in packet delivery ratio, although high throughput is a drawback. AODV-ABL [13] is an adaptive backup routing protocol which provides local repair. By overhearing reply messages (RREP) and data packets, backup routes are created in this protocol.…”

The Improved Overhearing Backup AODV Protocol in MANET

“…Lai et al and Zhou and Li [5,8] introduced AODV-ABL, which is an adaptive backup routing protocol along with local repair. In this protocol, backup routes will be created by overhearing reply messages (RREP) and data packets.…”

“…Zhou and Li [8] proposed AODV-BFABL. In scenarios with bidirectional traffic load, when the source node sends data to the destination, the destination node transmits data to the source as well.…”

“…In order to evaluate and compare the performance of listed protocols, three metrics were considered: packet delivery ratio, end-to-end delay, and control overhead. Table 2 shows the parameters in this simulation which were selected based on researches in [5,8,12].…”
