On Simultaneously Increasing MANET Survivability, Capacity, Power Efficiency and Security

  • Robert Hunjet Defence Science and Technology Group

Abstract

Increasing the capacity, survivability and power efficiency of wireless networks are often seen as competing goals. This paper shows that it is possible to pursue these goals simultaneously in ad hoc networks through the use of a multi-objective cross entropy optimisation operating on the placement of additional nodes and transmission power control. Encouraging results were obtained through simulation, with substantial capacity gains and associated transmission power savings achieved, whilst offering survivability through bi-connected topologies. This paper also discusses how the increase in power efficiency improves the security of the network by reducing the range at which messages within the network can be detected and decoded by eavesdropping nodes. A derivation of the optimal distance required between senders and receivers in the presence of noise is described, and the effects of relaying on overall network capacity and node throughput are discussed.

Author Biography

Robert Hunjet, Defence Science and Technology Group
Robert Hunjet received his Bachelor of Engineering (Computer Systems) with first class honours from The University of Adelaide in 2001. In 2004 he received his Graduate Certificate in Engineering (Communications Technologies) from the University of South Australia, and in 2014 he received his PhD from the University of Adelaide. Robert joined the Defence Science and Technology Group (DSTG) in 2001 and has since worked in the fields of network management and survivable networks. His work has ranged from quality of service implementation through the use of military bandwidth brokers, for which he was awarded the The 2004 Technical Cooperation Program Achievement Award, to the use of policy based network management and distributed network management in Defence environments. His current work is focused on wireless network performance, self organisation in tactical networks and wireless network survivability and, in 2015, has earned him a bronze level commendation for "Science and Technology Excellence" from DSTG.
