Wireless nodes (Laptop, PDA's and Mobiles) are assumed to have transmission power with different discrete level and different control to the limit of power of usage. The level of power available is one of the main concepts which affect all of ad-hoc wireless networks. Since, all of these networks are constructed without any infrastructure, where it based on the mobility of nodes that prevents the usage of any fixed infrastructure such as power cables. Hence, the power consumption is an important factor which affects the network life-time and transmission range. For that, the power consumption rate must be distributed for every node and the overall power of transmission must be minimized for each connection request, also the congestions must be decreased.
