In this paper, we propose a novel secured compression algorithm for an ad hoc network in which the packets are encrypted and compressed. The decompression and decryption using the same algorithm happens by a perfect synchronization between the sender and the receiver. It is observed that the proposed security concept may increase the level of confidence in this network. | International Journal of Computer Networks and Communications Security VOL. 2, NO. 12, DECEMBER 2014, 456–461 Available online at: ISSN 2308-9830 An Enhanced Data Security with Compression for MANETs Sekhar1 and Reddy2 1 Research Scholar, Department of CSE, Acharya Nagarjuna University, Guntur 2 Professor, College of Engineering, Acharya Nagarjuna University, Guntur E-mail: 1somasekharonline@, 2esreddy67@ ABSTRACT Ad hoc networking is a wireless networking paradigm for self-organizing networks that until recently has mainly been associated with military battlefield networks. However, with the availability of wireless technologies such as Bluetooth and and the development of the next generation networks, civilian applications that exploit the advantages of ad hoc networking are being envisioned. So far most of the research has been carried out to address the routing issues. Whereas other issues such as security, key management and network addressing have received considerably less attention and these issues need to be addressed before any successful applications will appear. In this paper, we propose a novel secured compression algorithm for an ad hoc network in which the packets are encrypted and compressed. The decompression and decryption using the same algorithm happens by a perfect synchronization between the sender and the receiver. It is observed that the proposed security concept may increase the level of confidence in this network.

The nodes in the network may move and radio propagation conditions may change at any time, creating a dynamic, rapidly changing network topology. Ad hoc networks require no centralized administration or fixed network infrastructure such as
