Abstract

In this paper we present simple modifications in the HWMP protocol for wireless mesh networks to incorporate different smart antenna transmission schemes. Our proposed amendments enable mesh nodes to select transmission techniques (spatial multiplexing, beamforming) adaptively according to the channel conditions. The advantages of diversity are exploited by transmitting control packets prior to beamforming communication. Simulation results illustrate that the modified HWMP (MHWMP) leads to a significant better throughput of the mesh network. Moreover, it enables a high degree of robustness wrt. wireless link failures for stationary mesh networks.
