Aggregate Information Efficiency In Wireless Ad Hoc Networks With Outage Constraints

In this paper we analyze the performance of wireless ad hoc networks with outage constraints. Using the performance metric aggregate information efficiency, we study the relationship among spectral efficiency, interference immunity, link activity and outage probability. We propose a numerical procedure to estimate the outage probability in a network as a function of several network parameters. Numerical results show that moderate modulation level and high coding rate maximize the network performance. ©2008 IEEE.256260Gupta, P., Kumar, P.R., The capacity of wireless networks (2000) IEEE Transactions on Information Theory, 46, pp. 388-404Sousa Elvino, S., Silvester John, A., Optimum transmission ranges in a direct-sequence spread-spectrum multihop packet radio network (1990) IEEE Journal on Selected Areas in Communications, 8 (5), pp. 762-771. , DOI 10.1109/49.56383Subbarao, M.W., Hughes, B.L., Optimal transmission ranges and code rates for frequency-hop packetradio networks (2000) IEEE Transactions on Communications, 48, pp. 670-678Mignaco, A.G., Cardieri, P., Total Information Efficiency in Multihop Wireless Networks IEEE International Performance Computing and Communications Conference, 2006.Nardelli, P.H.J., Cardieri, P., Aggregate Information Efficiency and Packet Delay in Wireless Ad Hoc Networks IEEE Wireless Communications and Networking Conference, 2008.Weber, S., Yang, X., Andrews, J.G., De Veciana, G., Transmission capacity of wireless ad hoc networks with outage constraints (2005) IEEE Transactions on Information Theory, 51 (12), pp. 4091-4102Yacoub, M.D., (1993) Foundations of Mobile Radio Engineering., , CRC PressHaykin, S., (1988) Digital Communications., , John Wiley and SonsCarlson, A.B., (1986) Communication Systems., , McGraw-HillWisitpongphan, N., Ferrari, G., Panichpapiboon, S., Parikh, J.S., Tonguz, O.K., QoS provisioning using BER-based routing in ad hoc wireless networks Vehicular Technology Conference, 2005.Weber, S., Andrews, J.G., Bounds on the SIR distribution for a class of channel models in ad hoc networks IEEE Globecom Conference, 2006
