In this thesis, we focus on mobile networks consist of a single base station as the
source transceiver, and multiple mobile stations as the receiving party. Applying
energy management on multicasting between the base station and mobile stations,
network users can conserve the energy consumed while wating for subscribing data
contents to come.
We referenced the SMBC-D (Scheduling over Multiple Broadcast Channels--the
dynamic model) algorithm proposed by R. Cohen et al., grouping users with high
request similarity, partitioning channels with a time-division duplexing scheme, and
putting mobile stations into sleep mode during channels that include no subscribing
data contents.
Since SMBC-D statically schedules fixed size channels, groups request fewer
data items will idle their channels after finishing their transmision, while groups
request more data items take longer time to finish their transmission. For such
problem, we propose a heuristic algorithm that makes use of these idle channels by
combining adequate consecutive idle channels, to improve channel utility, and lower
the overall energy consumed. We also process relevant computer simulations,
verifying that our method has better performance.
