Topology Discovering and Power saving Mechanism for Routing in a Tree of Ad-hoc Wireless Networks

Power management in mobile network is an open challenges where the power level in the network influences the network life time. However, there are a trade off between the power consumption and the connectivity in mobile networks. We present a topology control mechanism and a routing protocol for Ad-Hoc wireless networks that chooses the shortest path given the lower power consumption. The power consumption in forwarding a packet in the proposed topology is depends on only two main factors are the number of hops and the packet size. Our analytical results are confirmed by our simulation results where both has give the same results for power consumption in sending a packet taking in consideration only the power consumed in communication.
