Abstract

An exposition is undertaken on the performance related security modelling and evaluation of a robotic mobile wireless ad hoc networks (RANETs) and associated tradeoffs. It is based on the discrete event simulation analysis of a stable open gated queueing network model with infinite capacity, arbitrary configuration and multiple classes of packets under first-come-first-served and head-of-line rules. In this context, a quantitative case study on the trade-offs between performance and the wired equivalent privacy (WEP) security/selective security protocol is explored, based on generalised exponential transmission times and bursty arrival traffic flows characterised by an Interrupted Compound Poisson Process. Typical numerical experiments are carried out to evaluate the adverse effect of WEP security/selective security on performance and for illustration purposes, assess the adoption of a dual CPU towards performance enhancement of the RANET. A discussion on other vital related aspects such as broadcasting/multicasting and fault localisation in RANETs and their synergy with cognitive radio ad hoc networks (CRAHNs) is included.
