Hierarchical Energy Aware Dynamic Rate MAC Protocol for Maximizing the Life Time of Wireless Sensor Networks
In this paper, the authors deals with the problem for transmission of elastic and inelastic data transmission in the Wireless Sensor Networks (WSN). The proposed Energy Aware Dynamic Rate Medium Access Control (EADRMAC) model, the Cluster Head node (CH) in the cluster calculates the channel capacity i.e. number of on-going transmissions on the channel, and calculate the bandwidth required for transmission of real time data (in elastic) by traffic type utility function. Then the CH assigns the TDMA slots to the corresponding nodes based on the particular nodes type of data transmission and change the data rate according to the dynamic data rate calculation.
