## 4 Numerical Analysis and Results
### Network Selection for Different Services
We have defined all the bus routes with the optimal selected route for data allocation in Figure 16. All the buses have a maximum 150 TB capacity to carry and allocate data to all bus stops. \begin{table}

Table 12: Demands from all bus stops for data allocation

Figure 15: Proposed scheme for the problem. Table 13 shows the computation results of all the buses traversing all the bus stops in a unidirectional format and the total distance covered during each trip. In our analysis, we have used 16 stops, which will be covered by four buses, to fulfill their demands being allocated from a DC to deliver data. In Figures 17 and 18, we can see that it is possible to disseminate data either from the core traditional network or PTDD in the heterogeneous network. However, if we have delay-tolerant data and can utilize public transport, PTDD is an energy-efficient solution. Bus stops 1 and 2 have demands of 10 TB, bus stops 3 and 5 have demands of 20 TB, bus stops 4 and 6 have demands of 40 TB, and bus stops 7 and 8 have demands of 80 TB. As shown in Figure 18, bus stops 9 and 10 have demands for 10 TB data, bus stops 10 and 12 demand 20 TB data, bus stops 13 and 14 demand 40 TB data, and bus stops 15 and 16 have demands for 80 TB data. The bus will carry and deliver data at each bus stop as per their demands. For the maximum demands of 80 TB, we can analyze that the core network consumes 33% more energy than PTDD for data transmission. A bus that stops for 500 seconds, for a total 60 buses, can offload 64.8 GB/day, with an effective throughput of 22.03 MB/s. Moreover, transmission performance is also highly influenced by the number of buses in a day and the stoppage time at a bus stop. Figure 19 shows the transmission performance of each network for different data rates. We have considered that public transport will be using IEEE 802.11 ac as a network interface for data allocation. However, for comparison, we use the bandwidth of 512 MB/s and 1 GB/s in the traditional network to have a real difference. The outcome demonstrates that our proposed public transport network outperforms the traditional core network. ## 5 Discussion

We analyzed the various perspectives of traditional networks and every network has their standpoint and mode of communication. These networks rely mostly on big data analytics in the design of data communication networks. Therefore, these big data applications' survival would not be possible without the underlying support of networking, due to their extremely large volume and computing complexity. To elaborate further, we represent the three digital laws, [PERSON]'s law, [PERSON]'s law, and [PERSON]'s law, in Figure 20, which states that new products come into the market with each passing year

Figure 19: Transmission performance. Figure 18: Energy consumption vs. bus stop number for generated demands. with new technology. The basic idea of [PERSON]'s law is to double the storage capacity every 12 months. [PERSON]'s law is somewhat like [PERSON], but works on the processing speed of chips, which is doubled every 18 months. Moving forward to [PERSON]'s law, which estimates that bandwidth doubles every twenty-one months, this last component of digital experience lags for both storage and processing speed.
