Building high capacity, power efficient and survivable MANETs

Capacity, survivability and power efficiency are properties of wireless networks that designers strive to increase. These goals, however, may oppose one another. This paper introduces a method in which all three goals may be pursued 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.
