Abstract:
|
In this paper we analyze an unfairness problem
arisen when implementing the self-configuring clusterbased
DQCA AD HOC MAC protocol in a near-static
topology. When there is a low relative mobility among
terminals and the aggregate traffic offered to the network
is proximate to the maximum transmission capacity, the
DQCA AD HOC cluster set is unaltered for long periods of
time. In this case, the histogram of delivered data by each
node is not uniform, i.e. some nodes can deliver a high
percentage of their data while some others can never get
access to the network. This breaks the desirable fairness of
a MAC protocol. We propose and analyze a
straightforward solution that not only minimizes this
unfairness issue sharing in a more homogenous manner the
scarce radio resources, but also acts as an implicit powersaving
mechanism. Moreover, the proposed mechanism
increases the aggregate throughput in the network. |
