Abstract |
Utilizing multiple paths in parallel in order to improve performance is a widely adopted
approach for wireless mesh networks. Multipath utilization though, is more
complicated for wireless networks compared to their wired counterparts due to
interference.
In this thesis, different schemes that utilize multiple paths in parallel are
explored for static wireless random access mesh networks. Moreover, receiving nodes
have multi
-
packet reception capabilities while flows carry unicast traffic.
In the first pa
rt of the thesis, different forwarding schemes employing multiple paths
and different degrees of redundancy are compared in terms of delay and throughput.
An analytical framework for expressing these schemes' delay and throughput is
extended and evaluated
through simulations.
In the second part of the thesis, a distributed flow allocation scheme is explored,
aimed at maximizing average aggregate flow throughput while also providing
bounded delay. The proposed scheme employs a simple model for average aggre
gate
flow throughput that captures interference through the SINR model. As far as
interference is concerned, two different variants of the suggested scheme are
explored. In the first one, interference is approximated by considering only that link's
dominant interferering nodes. In the second variant, receivers apply successive
interference cancellation. The proposed scheme is evaluated both in terms of delay
and throughput through simulations.
