Abstract
Problem statement: The cooperation between the nodes is essential to d iscover and maintain routes in mobile ad hoc network. Due to th e presence of misbehaving nodes, the node cooperation is not always guaranteed as the nodes a greed during the route discovery phase. This phenomenon results in frequent network partitioning and it makes the routing process difficult. It als o degrades the overall network performance and increases the control overhead due to frequent route discovery. Approach: This study proposed an Acknowledgment based Reputation Mechanism (ARM) to detected and isolated the misbehaving links in mobi le ad hoc networks. The proposed system introduced a novel dynamic acknowledgment ratio to make the nodes to request its second hop successor in the source route to acknowledge the receipt of the pack et. This makes the nodes to detect the behavior of the next hop links and to select the trusted routes for its transmissions. Results: The measured parameters such as packet drop ratio, malicious drop, false de tection and send buffer drop are reduced greatly. T he results also compared with the existing scheme and with original routing protocol performance. Conclusion/Recommendations: The proposed scheme performs better in detecting and isolating the misbehaving links. The overall network packet drop was decreased which in turn increase the overall network throughput. This shows that the proposed ac knowledgment scheme discovers the trusted routes with the presence of misbehaving nodes.
Highlights
Mobile Ad hoc Networks (MANETs) is an autonomous collection of mobile devices which self organize to create a network by exploiting their wireless interfaces without a requirement for an existing infrastructure or any centralized administration
The routing protocol plays a vital role in establishing route between the mobile nodes and maintenance of the routes in these networks
Misbehaving nodes comes into existence in a network due to scarcely available resources of mobile nodes such as battery power and computational resources (Marti et al, 2000)
Summary
Mobile Ad hoc Networks (MANETs) is an autonomous collection of mobile devices which self organize to create a network by exploiting their wireless interfaces without a requirement for an existing infrastructure or any centralized administration. These components are added as an add-on into the reduces the control overhead occurred due to TwoHopAck. Each node maintains a One Hop Connectivity List (OHCL) which contains the neighboring node information (IP/MAC address) based on the packets overheard / received. When hi-1 is disclosed to Originator, it can be used to verify the integrity of the TwoHopAck packet proposed system has been measured by using the following parameters: received last time by calculating the MAC and comparing it with the received one This is the socalled “delayed disclosure” technique due to Hu et al (2003).
