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.
