AN EFFICIENT WI-FI INTERNET ACCESS FOR MOVING VEHICLES USING SWIMMING SCHEME
Journal Title: Elysium Journal of Engineering Research and Management - Year 2015, Vol 2, Issue 5
Abstract
Accessing internet from moving vehicles is demanding and has been rapidly growing. Due to mobile detonation, the overloading issue of cellular networks is increasing. So, the Wi-Fi based accessing is considered to offload cellular networks that are a promising technology for internet access. But, it poses many problems in highly dynamic vehicular environments for Wi-Fi networks. In order to solve this problem, this paper proposes a better scheme, namely, SWIMMING to support the Wi-Fi based internet access for moving vehicles. For this purpose, a group of Access Points (APs) are employed to communicate with the client. In this scheme, the AP in the group accomplishes the delivery ratio to the client once the transmission is succeed. To avoid high packet loss, all APs present in the group are configured with same MAC and IP addresses. Moreover, the link reliability is enhanced by exploiting the AP diversity and opportunistic transmission. In this paper, the probability of successful transmission is improved by delivering the packet at two stages in downlink communications. The main advantages of this work are, it improves the efficiency of channel utilization, it provides seamless roaming within the coverage of the entire network, and it overwhelms the issues of unreliable links and unstable connections. The experimental results evaluate the performance of the proposed system in terms of Packet Delivery Ratio (PDR), throughput and packet loss.
