Hierarchical Energy Tree Based Routing Algorithm (HETRA)
Energy remaining in sensor nodes is used as additional parameter for taking routing decision in the proposed HETRA. The remaining energy in the sensor nodes is used to place the nodes in either Level 1 or Level 2 in the logical HET generated.
With these specific values the algorithm is used for the proposed WSN, along with the proposed routing algorithm HETRA. AIMD is suitable for traffic where the data is transferred at almost fixed rate and unsuitable for burst traffic.
By using different protocols such as AODV, DSDV, LEACH, and HETRA, energy efficiency and NLT analysis are made.

HETRA is implemented as a new WSN routing protocol in ns 2.
Assuming the TCP/EXP congestion control, Figure 5 gives the values of NLT for DSDV, AODV, LEACH, and HETRA routing protocols using the node distribution Pattern1.
This shows that the combination of HETRA with TCP/EXP performs better for all the node distribution patterns compared with other routing and congestion control algorithms.
Figure 15 shows the values of DANLT product for seven node distribution patterns for various routing algorithms of AODV, DSDV, LEACH, and HETRA with TCP/EXP as the congestion control algorithm.
The result clearly indicates that the combination of HETRA with TCP/EXP performs better for all the node distribution patterns.

Miss Pin Up is in form, but may need further nowadays, so most interesting of the remainder is Hetra Heights, who was a good second on the July course in August but disappointed after a month-and-a-half break last time.
