Ensuring minimal communication overhead in low bandwidth network file

Abstract

All wireless networks are resource constrained, the battery power, memory and bandwidth are main constraints along with security of information in wireless networks. Running of ordinary file systems on such wireless networks can result in short battery life and bandwidth dilemma for large file sharing, which results in high latency and unbearable delays which user do not consider while working on wireless networks, also the security is second main issue in wireless networks as any false node can inject his packet or private information can be divulged to someone who is not intended, so there is paramount need of an efficient and secure file system for wireless networks. The paper describes the need of secure and bandwidth efficient file system for wireless networks and also proposes a file system which is secure and bandwidth efficient and can become a part and parcel of wireless networks. Simulation results are evident of the performance achieved for our proposed scheme. Proposed methodology can save maximum bandwidth by taking advantage of cross file commonalities, in best case analysis it will just transmit a packet containing just hash tree. © 2012 Springer Science+Business Media.
