Title
A Classified Slot Re-allocation Algorithm for Synchronous Directional Ad Hoc Networks.
Abstract
Several typical synchronous directional media access control (DMAC) protocols are proposed for directional ad hoc networks (DAHN), e.g., directional transmission and reception algorithms (DTRA) [4]. One of the slot allocation problems of these DMACs is the unfairness between links, or link starvation, which is caused by the distributed feature of DAHN. That is the earlier discovered link reserve much more slots which results in the later discovered links have few slots to reserve. To address the unfairness problem, in this paper a classified slot re-allocation algorithm (CSRA) is proposed. The basic idea is to classify the data slots into four types according to their status in the data transmission phase, and then when the unfairness problem is found different types of slots are re-allocated. The re-allocation order of these four types of these slots are free slots, sending slots, neighbour transmitting slots, and receiving slot. Extensive simulation are carried out to evaluate the performance of the proposed CSRA. The simulation results show that the Jain’s fairness index is improved with little loss of the network throughput.
