Carrier sense multiple access (CSMA) is the conventional medium access method used in wireless ad hoc networks. it can be enhanced as a space-division based CSMA (namely, SD-CSMA) by using multi-antenna techniques, which allows concurrent link communications in the network. In this paper, we present a MAC design that can adaptively switch between CSMA and SD-CSMA in multi-antenna based ad hoc networks...
We investigate a transmission scheduling protocol that exploits direct-sequence spread-spectrum (DSSS) modulation to improve the performance of a mobile, ad hoc network. Since DSSS allows for packet capture in the presence of other nearby transmissions, multiple-access interference is less detrimental to network performance. We design a new transmission scheduling protocol that takes advantage of...
