Energy and mobility-aware topology control in heterogeneous mobile ad hoc networks

This paper studies the topology control in heterogeneous mobile ad hoc networks (MANETs), where mobile nodes have different transmission ranges and moving speeds. We consider symmetric communication model where two nodes can communicate directly if and only if they are within the transmission range of each other. We propose energy and mobility-aware proximity graphs extensions in which a neighbour's utility function has been used instead of distance parameter to choose the new neighbours and update the transmission range. The proposed utility function considers both power and mobility parameters for the neighbour nodes. The proposed graphs extensions are localised in which they depend on information from the first-hop neighbours only. We introduce locale algorithm to update the mobile network graphs. To study the performance of the proposed graphs, a mobile ad hoc network environment has been simulated.
