Design and Analysis of Secure Quality-Of-Service Routing in Mobile Ad Hoc Networks

Bharat Bhushan naib, Dr. V.R. Singh

Abstract


An ad hoc network is a collection of computers (nodes) that cooperate to forward packets for each other over a multihop wireless network. Users of such networks may wish to use demanding applications such as videoconferencing, Voice over IP, and streaming media when they are connected through an ad hoc network. Because overprovisioning, a common technique in wired networks, is often impractical in wireless networks for reasons such as power, cost, and government regulation, Quality of Service (QoS) routing is even more important in wireless networks than in wired networks. Though a number of QoS-routing protocols have been proposed for use in ad hoc networks, security of such protocols has not been considered. SQoS relies entirely on symmetric cryptography. Symmetric cryptographic primitives are three to four orders of magnitude faster (in computation time) than asymmetric cryptography. In this research paper, SQoS is simulated using NS-2 and the parameters used for simulation are throughput, packet-loss and end-to-end delay. SQoS helps in providing security and Quality of Service in MANET.
