Multi Path TCP Over Network Coding for Wireless Network

When hardware and software are combined in item, you get a wireless sensor network (WSN). In WSN, both low and high-end devices (such as sensors and servers, respectively) are online. WSN's RPL routing protocol was developed so that even in weak and lossy connections, data may be collected efficiently and reliably. The RPL (Routing Protocol for Low-Power and Lossy Networks) network builds and maintains its topology using objective functions like hop count or ETX (Expected Transmission Count). Constructions like the Destination Oriented Directed Acyclic Graph (DODAG) that rely on the Rank attribute inevitably led to issues like greedy parent election, thundering heads, and network instability. When a Software Defined Network (SDN) is used with a WSN, the routers are managed by a controller server node. The network is dynamic since it contains both mobile and power- limited nodes. The term “routing” refers to the process of determining the best path between two points. In this paper, a software-defined- networking-based Energy Harvest routing approach is provided. The proposed approach focuses the link's capacity and the path's available bandwidth into a single, manageable entity. The SDN controller node can reconfigure the paths on the fly. As a result of a decrease in conjunction- related packet loss, the packet delivery ratio improves. The data- driven design solution that facilitates nimble and versatile system organisation through a collaborative link between DDS and SDN. NS2 simulator is used to do simulations of the proposed method in a variety of settings.
