The speed of data transfer and the amount of space within the communication service, taking into account the cost, security,
capacity, and specifications of WiMAX is highly important in communications. There are varies difficulties for routing in WiMAX,
for example, delay, long scheduling, interference and progressively stringent Quality of Service (QoS) backing and burden parity.
This paper proposes a multi-transceiver and multi-channel centralized routing and scheduling algorithm to avoid the impact of
packet collision with neighbor nodes. The proposed algorithm looks for a short path from the subscriber station (SS) node to Base
station (BS), while the optimal path is achieved when the whole path has the lowest (energy bit minimum routing (EBMR)). After the
route is fixed, and the traffic demanded at each node is known, the total traffic arriving at a node is centrally scheduled in order to
avoid the transmission interferences. The results from the multi and nearest multi-transceiver systems showed that the proposed
algorithm has effectively minimize the length of scheduling in the in multi \ nearest multi -transceiver system. Moreover, the channel
utilization ratio (CUR) is found to be improved over the implementation of the proposed system.
