Unit 3 Assignment 1 Using Mobile Network

Decent Essays

In this smart world there is a rapid growth in using mobile network for requesting many queries, especially videos.Problem is more Base Staion (BS) is required for providing a continuous service, for the user to view videos without getting buffer, or in degrading of video quality. Since more BS are required, all BS has to be active all time, therefore energy requirement is more. It cause more power consumption, also if BS is reduced for save power it leads to poor quality of service(QOS). During peak traffic load during rush hours, wireless access network must be over deployed. It requires lot of BS to be active even when many times slots in a BS are free while providing service. Also, in a low-traffic period, the user will not request any data, but the BS have to be active. …show more content…

Identification of user location whether the user is nearer to the BS or moving away from the BS. When the user is nearer to the BS, there will be continuous service, all the remaining BS which is not active could be put into sleep. SDN concept to the energy saving and optimizing problems in wireless access network to solve the “channel state prediction problem”, which in fact is the correlation between user’s location and channel capacity. If a user’s future location is predictable, the upcoming data rates can be anticipated from “wireless coverage information” stored in the network controller database. This protocol is between control plane and data plane, and it can support the feasibility of SDN. The database is able to be updated in real-time by the corresponding strategy Stored in users terminals. The energy consumption of BSs is more than 50% of all energy used in the wireless access network Consequently, the research of energy saving in BSs is essential
