In this paper, a decentralized adaptive TDMA scheduling strategy (DATS) for Vehicular Ad-hoc Network (VANET) with the ability of reducing the collision of nodes occupying the same slot is proposed. In DATS, slots are divided into left and right slot sets. The ratio between the two slot sets can be adjusted according to the node density. According to the locations and neighbors' slots, nodes competition...
Given the special requirements from wireless sensor networks and the disadvantages of current MAC protocol, a new cross-layer MAC protocol, which combines the physics layer and a MAC protocol, is introduced. The former layer is based on direct-sequence spread-spectrum, and the latter busy tone. First the physics layer and MAC layer were designed concretely, and then the power consumption and duty...
