In this period it is intended to implement and test several WMSNs in which the energy level of the nodes does not remain constant, making use of the NS-3 tool. To do this we will use a mesh networking model, based on the standard IEEE 802.11s, along with an energy framework capable of modelling the energy source and the energy consumption of the network nodes. All these models are already provided by NS-3. In these simulations we will generate several topologies, both regular and random, and we will constantly monitor the energy levels of the nodes. The simulations will be performed multiple times for each topology to ensure that the results obtained are reliable. The integration of this energy model with the simulations of WMSNs already performed and exposed in chapter 3 of the PDI report (PDI Report), will be very important, since it will allows us to simulate and evaluate the energy-aware channel assignment algorithm proposed on this thesis.

In this period we will specify the mode of the operation of the channel assignment algorithm. The main goal is to develop a solution to assign the communication channels to the nodes, capable of improving the energy efficiency of the network. Taking into account the state of the art solutions exposed in chapter 2 of the PDI report (PDI Report), we will try to design a solution which, based solely on the network topology and on the energy level of the nodes, will be able to improve significantly the lifetime of WMSNs. The specification of this algorithm will probably result in a modification of the TILIA algorithm, giving rise to a new algorithm named E-TILIA.

15 Mar - 20 Mar

After the designing of the algorithm we will implement E-TILIA in a Python script. The idea is to modify the existent TILIA Python script, adapting it to the new algorithm.

Close

22 Mar - 27 Mar

In this period we will extensively test the algorithm developed, using the Python script implemented. To do this we will generate several regular topologies, each one having a different number of nodes, and we will run the E-TILIA regularly to evaluate if the algorithm is capable of improving the energy efficiency of the network.

29 Mar - 03 Apr

After the extensive testing with regular topologies we will then test our algorithm with random topologies, following the same procedure.

Close

05 Apr - 10 Apr

After the algorithm has been tested extensively with the simulation tool, we will then prepare a test-bed, using Raspberry Pi computers, to test the algorithm in real conditions. The idea is to create a WMSN using several Raspberry Pi computers. In this preparation a special attention has to be given to the routing protocol to be used, and to the procedure that is going to be responsible for gathering all the necessary input data for E-TILIA.

12 Apr - 17 Apr

In this period the algorithm will be adapted to be used in the Raspberry Pi test-bed.

Close

19 Apr - 24 Apr

In this period, after the preparation of the test-bed, the algorithm will be extensively tested in real conditions. This will be extremely important because it will allow us to understand if the simulated results are in agreement with the results obtained in real conditions. This will ultimately enable us to assess the algorithm quality.
