Improving the Lifetime of Wireless Ad Hoc Networks Using Power Aware Routing
This paper discusses the energy saving control problem in ad hoc wireless networks. The problem can be formulated as a number of randomly placed nodes in a plane with a given area and a required traffic load constrained by end to end delay bounds. The authors try to find an optimized routing path that can meet the Quality of Service requirements and minimizing the total consumed power of nodes. In addition to that, the network life time must be maximized by considering fairness among power consumptions of nodes indicated by the variance between nodes consumed power levels. An optimal algorithm has been proposed to solve the problem using "Integer linear programming" along with a set of power and energy constrains.
