A Systematic Study and Analysis of Security Issues in Mobile Ad-hoc Networks

2. Related Work

This section presents a detail study and review of advanced approaches proposed by eminent researchers in this field of security in MANET. Transmission of audio data with secured mechanism has been discussed in Athulya and Sheeba’s work (2012) where the authors have provided dual safety measures by encrypting and decrypting the audio at each node in the route using stream ciphering method. Security threats and their possible solutions have been discussed in Jan Von Mulert, Ian Weich and Winston K.G. Seah’s research (2012), and it also focuses on how modification of data is done using optimization technique for security. Praveen Joshi (2011) discusses about the various security problems and how to prevent them which are adopted in the network layer. Spoofing attack and their prevention techniques has been discussed in Yuseok, Tae-Hyung, and Jong’s (2012) work. The author proposed a model i.e. PBM (Policy Based Management) that deals with 4 entities in (Bostjancic & Timecenko) such as QoS, network resources, configuration and security. It has discussed about the vulnerability, challenges and security attacks on ad-hoc routing protocols. A bargained hub may disregard the secrecy rule of security and uncover vital data like private and open keys, status of hub, passwords, ideal course to approved hubs, geographic area of hubs and other control information in parcel headers to unapproved hubs introduce in the system (Dhivya, Karthik & Kumaran). A secured on-demand routing protocol has been proposed in (Wan, Ren, & Gu) that prevents various attacks in MANET and another regression based trust model for MANET has been implemented in (Venkataraman, Pushpalatha, & Rao, 2012) that ensures guaranteed packet delivery in wireless medium. Marchang and Datta (2012) proposed a light weight trust based routing protocol that prevents any external attacks in MANET and a mobile agent based secured platform has been designed in (Rath & Pattanayak, 2017) that ensures improved network life time with better throughput when compared with other similar approaches.
