Analytical Model for Improved QoS and Security in Wireless Ad Hoc Networks

Abstract

QoS and Security are necessary features for wide deployment of wireless ad hoc networks. Existing ad hoc networks provide little support for them. In this paper, we have proposed a mathematical model for improving both QoS and Security. We also present a model that takes into account the number of nodes, the Poisson packet arrival process and service process. Here, wireless ad hoc networks are modeled as M/M/1/Q queuing networks and the expressions for the packet loss rate and packet delivery ratio are evaluated. The mean service time of nodes is evaluated and used to obtain the packet delivery ratio. The analytical results are verified by simulations and numerical computations.
