Thesis Contributions. ‌ As a first contribution in this thesis, the author proposed a novel cross-layer design for the communication protocol of ad-hoc networks in Chapter 3. To accomplish this goal, a utility maximisation problem is considered that results in a cross-layer design for Multipath TCP, involving congestion control, scheduling and routing. Utility maximisation is performed via an optimisation problem that includes source-rate, queuing delay and scheduling constraints. The problem is solved for both fixed channels and time-varying channels. The solution of the optimisation problem exploits the Lagrangian. In addition, the outcome of the optimisation problem is formulated in two possible methods of scheduling: perfect scheduling and distributed scheduling. Each method provides a different trade-off between performance and complexity. In perfect scheduling, all nodes in the communication network contribute to realise the optimum solution. In distributed scheduling, only the neighbour nodes can contribute, which makes the implementation simpler. The chapter analytically proves that the optimisation problem converges to a global optimum in all methods. The results are compared with other algorithms in the literature. This comparison revealed that the proposed algorithms outperform existing algorithms. This is due to the fact that the pro- posed algorithms take into account the queuing delay and the available multipath connections. Specifically, the proposed algorithms demonstrate a higher source rate, lower congestion price and faster optimisation convergence to the optimum solution. The second contribution of this thesis is presented in Chapter 4, where the author compares several variants of MPTCP that are available in the literature for wireless IoT networks. The compared protocols are traditional MPTCP, MPTCP- TSC (MPTCP- Traffic Split Control) and XxXX TCP (Redundant MPTCP). MPTCP-TSC is a greedy protocol which splits traffic to minimise the cost (which is a weighted sum of the required transmission rates) while satisfying the delay constraints. On the other hand, XxXX TCP sends data redundantly over all available multiple paths in the network. These protocols were not examined for IoT wireless networks before this work. It is shown in the numerical results that XxXX TCP has the lowest number of transmissions and the lowest delay compared to other schemes. To improve the delay further, the chapter introduces the Opportunistic Routing (OR) protocol to all considered...
