Abstract:
|
B-PLC (Broadband Powerline Communications) is an access technology which
utilizes the low-voltage cables network to offer telecommunications services to the
subscriber. The network is organized according to the actual available infrastructure
of the electrical power lines. The whole B-PLC network can be organized as a multicell
system. Each B-PLC cell contains a base station providing access to all
subscribers and connected itself to the backbone network. Each cell requires an
amount of transmission capacity for serving its subscribers. The transmission in a cell
may crease interference to the others; therefore some of them cannot utilize the same
frequency or time slot at the same time.
Because the bandwidth requirements from each cell are dynamically changed, e.g.
users turn on or off, it is necessary to propose and apply dynamic bandwidth
management mechanisms to organize the limited bandwidth between multiple B-PLC
cells. The mechanisms have also to improve the efficiency of the bandwidth usage.
The overall network performance depends on the methods utilizing for bandwidth
organization and its parameters.
Lots of algorithms have been proposed to improve the quality of service of the
channel assignment in telecommunications. This thesis proposes an algorithm based
on the game theory to improve the channel allocation in a PLC network. A distributed
and dynamic channel assignment method is proposed to improve the static method. In
a fair situation each cell has the same resources per user. In the proposed algorithm
each station acts for itself in a selfish way, but taking into account the fairness
between users. Furthermore, it is intended to reach a situation in which the best
channel reuse is achieved. |
