Raghu Vamsi.P, Payal Khurana Batra, Krishna Kant

TL;DR
This paper introduces BT-GPSR, an integrated trust-based routing model for wireless sensor networks that combines reputation and weight trust systems to enhance security and packet delivery in the presence of malicious nodes.
Contribution
It presents a novel integrated trust model using reputation and weight systems combined with GPSR, outperforming existing trust-based routing methods.
Findings
BT-GPSR improves packet delivery rates in malicious environments.
The integrated trust model outperforms conventional reputation and weight-based methods.
Simulation results validate the effectiveness of the proposed approach.
Abstract
Geographic routing offers guaranteed packet deliv- ery in a dense network. In this routing, packets are forwarded to a node which is nearer to the destination with an extensive use of location information. However, research studies in Mobile Adhoc Networks (MANETs) and Wireless Sensor Networks (WSNs) have shown that packet delivery percentage can degrade substantially when malicious nodes are found in the network. Conventional cryptography techniques can be adopted in order to deal with ma- licious nodes, but they cannot mitigate outsider attacks. In recent years, a societal pattern called trust is used as a tool to mitigate security attacks. Numerous researchers have proposed security solutions by adopting trust in routing algorithms. However, each solution has its own strength and weakness. In this paper, an integrated approach by using reputation and weight based trust systems backed…
