Abstract

Mobile cloud computing is the revolutionary distributed computing research area which consists of three different domains: cloud computing, wireless networks and mobile computing targeting to improve the task computational capabilities of the mobile devices in order to minimize the energy consumption. Heavy computations can be offloaded to the cloud to decrease energy consumption for the mobile device. In some mobile cloud applications, it has been more energy inefficient to use the cloud compared to the conventional computing conducted in the local device. Despite mobile cloud computing being a reliable idea, still faces several problems for mobile phones such as storage, short battery life and so on. One of the most important concerns for mobile devices is low energy consumption. Different network links has different bandwidths to uplink and downlink task as well as data transmission from mobile to cloud or vice-versa. In this paper, a novel optimal link selection algorithm is proposed to minimize the mobile energy. In the first phase, all available networks are scanned and then signal strength is calculated. All the calculated signals along with network locations are given input to the optimal link selection algorithm. After the execution of link selection algorithm, an optimal network link is selected.

Keywords

Abstract

With the increasing use of wireless sensor networks in industrial settings, a new type of network topology, mesh networks, has emerged in today's market. The success of wireless networks in every field has made wireless networks, an emerging key technology for the next generation wireless networking. The various features of wireless mesh networks have attracted the research community, which led to the rapid growth of this technology, inspiring many applications. Many challenging technical issues still exist in this field. This paper compares the reliability and flexibility of the mesh network with other two traditional wireless network topologies, namely point-to-point and point-to-multipoint networks, and illustrates why and how the mesh network has advantages in these areas with the help of a case study.

Keywords

Wireless Mesh Networks, Point-to-Point Networks, Point-to-Multipoint Networks.
