In wireless ad hoc networks, maximizing the network lifetime under energy constrained network is a critical problem. Differing from the former work on topology control which extends network lifetime by the reduction of energy consumption, our work directly takes network lifetime as a starting point to maximize network lifetime. In this paper, based on the more widely used definition of network lifetime and the more realistic energy model, we present an adjustable structure called ALPS to control topology. ALPS enables each node to adjust the topology independently between RNG and UDG via a parameter E-elec and allows nodes to have different path loss exponent. We show properties of ALPS by proof or simulation: (1) It preserves connectivity and symmetry; (2) it preserves all maximal lifetime paths between any pair of nodes under different E-eleo; (3) compared with previous works GG, Kneigh and CBTC, it can effectively prolong network lifetime.
