Abstract
In the earlier transmission schemes the base station is responsible for continuous transmission of packets to the receivers when they are not received properly.in these type of re-transmission the BS experiences a great traffic. This paper considers the concept of channel allocation scheme with partial information of device locations. To implement the users in the geographical area is divided into sub clusters, each sub cluster contains one ACK device and few number of NACK devices. The transmission can be done in the TDMA mode. Then the next step is the joint optimization of NACK-devices association and transmission powers of re-transmitters as an MINLP problem, minimizing the total energy consumption of re-transmitters. Finally solving the problem by using an efficient algorithm for this problem to find good association pattern and transmission power.
