Modeling and analysis of data flow in MAC layer of WSN-MCN convergence network

With enormous growth of wireless communication technologies, mobile phone plays an important role in future development of ubiquitous network. New cellular devices are equipped with powerful computing, communicating and storage facilities which will improve scalability, energy efficiency and decrease packet delay, etc. The performance metrics like coverage, enhanced target tracking and superior channel capacity can be increased by using mobile sink over a static sink in Wireless Sensor Network (WSN). On the other hand Mobile Cellular Network (MCN) has technology of wide coverage area, powerful nodes and network robustness but it's deployment is expensive. Therefore, integration of MCN and WSN is the need of the hour. This integrated type of communication network minimizes the data loss which is an important challenge that occurs at medium access control (MAC) layer. Therefore Quality of Service (QoS) metrics for data flow is emerging issues which need to be solved. In this paper, we study the issues in convergence of MCN and WSN with respect to MAC layer. An analytical model is designed to study performance metric for data traffic flow from sensor node to mobile phone. The QoS measures in terms of data packet delay, loss of data packets etc. are represented in the form of graphs.
