An Enhanced Multipath Strategy in Mobile Ad Hoc Routing Protocols

Abstract

The various routing protocols in Mobile Ad hoc Networks follow different strategies to send the information from one node to another. The nodes in the network are non static and they move randomly and are prone to link failure which makes always to find new routes to the destination. This research mainly focused on the study of the characteristics of multipath routing protocols in MANETS. Two of the multipath routing protocols were investigated and a comparative study along with simulation using NS2 was done between DSR and AODV to propose an enhanced approach to reach the destination maintaining the QoS. A possible optimization to the DSR and AODV routing protocols was proposed to make no node to be overburdened by distributing the load after finding the alternate multipath routes which were discovered in the Route discovery process. The simulation shows that the differences in the protocol highlighted major differences with the protocol performance. These differences have been analyzed with various network size, mobility, and network load. A new search table named Search of Next Node Enquiry Table (SONNET) was proposed to find the best neighbor node. Using SONNET the node selects the neighbor which can be reached in less number of hops and with less time delay and maintaining the QoS.

Review on Secure Ad-Hoc Networks for Wireless Sensor Network

“…A comparative study is made based on performance metrics like packets delivery ratio and packets dropped [4]. The author has done a comparative study with simulation using NS2 between DSR and AODV routing protocol to overcome a load of nodes, and simulation shows the comparative performance of the routing protocols, and SONET is proposed for efficient routing scheme [5]. The triple-factor approach has a very similar security feature w.r.t.…”

Secured Approach towards Reactive Routing Protocols Using Triple Factor in Mobile Ad Hoc Networks

“…In the network each node plays a dual role as a host by the forwarding and as a router in routing packets to the destination. Maintaining security is an important function of any of the routing protocol in each phase of the networking function [1]. Because of the non-static topological behaviour of the network and due to being the network open which allows the network to grow and shrink due to addition and deletion of the nodes anytime gives chance for the intruder nodes to disturb the normal routing process.…”
