A network routing method based on received power of repeater nodes and QoS for mobile ad-hoc networks

In this paper, a network routing method based on Quality of Service (QoS) for ZigBee-based mobile ad-hoc networks in a multipath fading environment is studied. The proposed routing method adapts the priority information for QoS to Route Request message in the route discovery process and HELLO message in the route maintenance process. According to the priority information, periods elapsed between transmitting Route Request and Hello messages are controlled according to QoS mechanism. Computer simulations about route discovery times, route effective time, throughput performances, and delay-time distribution for real time and non-real time packets are carried out. We reported the results of the computer simulations and the effectiveness of the proposed routing method.
