“…To collect information from neighbour nodes, this novel routing strategy employs a broadcasting mechanism. During the flooding process, redundant paths are discovered, increasing overhead in the network [31]. Preemptive-DSR (PDSR) protocol predicts connection failures, but the mechanism is slow and costly.…”

Mobile ad-hoc network (MANET) has attracted the attention of networking industries owning to their desirable characteristics such as multi-hop routing, self-configuration, selfhealing, self-managing, reliability, and scalability. Routing over wireless mobile networks is a critical problem due to the dynamic nature of the link qualities, even when nodes are static. A key challenge in MANETs is the need for an efficient routing protocol that establishes a route according to certain performance metrics related to the link quality. The routing issue in MANETs is generally concerned with finding a good path between the source and the destination pairs. Based on that, there is a demand for the development of a high throughput routing protocol. The impact of a single-path routing protocol and a multi path routing protocol on the performance of MANETs is required to be investigated. In this work, a performance comparison in terms of throughput, packet delivery, routing overhead, and end to end delay of wellknown routing protocols such as AODV, AOMDV, and OLSR using network simulator version 2 (NS-2) has been introduced. The simulation results of this work show that the single-path AODV protocol out performance the multi path OLSR and AOMDV protocols in terms of throughput and packet delivery ratio. In addition to that, the single-path routing protocol presents less routing overhead in comparison to the AOMDV and OLSR. While the OLSR and AOMDV demonstrate a relatively better end to end delay in comparison to the AODV protocol.

“…Shobha and Rajanikanth [41] proposed an enhancement called relay routed DSR to reduce the amount of RREQ and control packets. This protocol functions according to the mobility information collected from the neighboring nodes during the flooding phase and uses it to select the relay nodes where RREQs should be sent during the relaying phase.…”

Efficient Route Discovery and Link Failure Detection Mechanisms for Source Routing Protocol in Mobile Ad-Hoc Networks

et al. 2020

The rapid advances in the wireless communication industry have paved the way for the enhancement of wireless mobile ad-hoc networks (MANETs) to support various domains including civilian environments, emergency operations, and military affairs. Source routing in MANETs is subject to some issues such as changes in the network topology, which lead to frequent link breakages that may increase the requests of route discoveries. Thus, this paper aims to enhance on-demand source routing protocols by proposing two mechanisms, a zone-based route discovery mechanism (ZRDM) and a link failure prediction mechanism (LFPM). ZRDM aims to control the flooding of route requests, and LFPM aims to avoid route breakages caused by node mobility. The performance of the proposed mechanisms was evaluated using network simulator 3 in terms of normalized routing load, average end-to-end delay, and packet delivery ratio. The experimental results showed that the proposed mechanisms outperform well-known mechanisms such as the dynamic source routing (DSR) protocol, reliable DSR, and zone-based DSR and segment-based DSR.

In this paper, we propose an enhancement technique for dynamic source routing protocol (DSR) using prefetching of frequently used routes in the cache. DSR is a popular on-demand reactive routing protocol in mobile ad-hoc networks (MANETs) which uses flooding for route discovery and route maintenance only when a node has data that needs to be transmitted. Flooding causes serious redundancy, contention and collision in the network which increases the overhead of transmission in a dynamic network where the nodes have different mobilities. Most of the research work on prefetching has focused on using this technique for improving data access in clustered networks; but this involves a lot of overhead in maintaining the clusters. Hence we have considered a non-cluster based network with random movement of nodes for our analysis. Our principal aim is to reduce the amount of flooding of the route-request (RREQ) packets in the network so that the overhead can be reduced. In order to achieve this we propose a prefetching algorithm which involves two steps. First, we timestamp each and every route cached in a node's route-cache table based on the mobility of the nodes. Second, we initiate prefetching of only the frequently used entries from route-cache table when their respective timestamps are on the verge of expiring. Simulations carried out on DSR have shown that this technique can reduce redundant flooding to a great extent, thus making DSR more efficient.
