Continuous quorum-based multicast power-saving protocols in the asynchronous ad hoc network for burst traffics

In this paper, we propose a continuous unicast quorum system named C-coterie such that PS hosts have continuous intersections to transmit burst traffics. In order to transmit burst unicast traffics, we design a unicast PS protocol adopting C-coteries. We define the rotation continuous closure property for certifying the continuous intersection between two quorums even asynchronous clocks. We propose two C-coteries, C-Grid and C-Torus, which satisfy the rotation continuous closure property. In order to transmit burst multicast traffics, we propose a continuous multicast quorum system named C(m)-arbiter and define the rotation continuous m-closure property for certifying the continuous intersection among m quorums even asynchronous clocks. We design a multicast PS protocol adopting C(m)-arbiters for m hosts to transmit burst multicast traffics. We propose two C(m)-arbiters, Uniform C(m)-arbiter and CRT C(m)-arbiter, that satisfy the rotation continuous m-closure property. Finally, we use NS2 to simulate QoS for transmitting burst traffics such as the MTIM frame quantity, packet arrival ratio, transmission delay and throughput. As shown in the simulation results, continuous quorum systems we proposed outperform non-continuous quorum systems, especially in the heavy load. It is because the continuous quorum systems have more opportunity to have continuous intersections such that the sender could continuously transmit burst traffics during continuous intersections.
