Routing approach based on rate of transmission failure in ZigBee networks with changing mobility
In this paper, we propose and evaluate a Transmission Failure Based Routing Algorithm (TFBRA) for low power consumption in ZigBee networks with changing mobility. We analyse the traffic with different routing algorithms which are stated in ZigBee specification. The effects of different factors on data communication are discussed. As the variation of mobility results in changing possibility of sending routing request as well as varying routing performance, the probability of transmission failure in one hop is used to describe node mobility. The TFBRA compares this rate with the threshold which is computed based on hardware condition to decide the routing scheme in ZigBee network. The scheme utilises the information in neighbour table and network address for mobility estimation without any extra communication. The simulation results show that the proposed approach achieves better performance than original routing schemes in ZigBee specification by obtaining lower network load and larger ratio of successful data transmission.
