“…For example, capture has been shown to increase throughput and decrease delay in Aloha [1], [30] and 802.11 networks [3], [16], [17], [40] with no additional effort. Some physical and link layer protocols have explicitly exploited the capture effect in order to improve performance such as Capture Division Packetized Access (CDPA) [8] and Power Control during Transmission (PCT) [19]. Similarly, the capture effect has been used as a mechanism for providing different quality of service to different clients by allowing them to control transmission power [31].…”

Abstract-We present the Flash flooding protocol for rapid network flooding in wireless sensor networks. Traditional flooding protocols can be very slow because of neighborhood contention: nodes cannot propagate the flood until neighboring nodes have finished their transmissions. The Flash flooding protocol avoids this problem by allowing concurrent transmissions among neighboring nodes. It relies on the capture effect to ensure that each node receives the flood from at least one of its neighbors, and introduces new techniques to either recover from or prevent too many concurrent transmissions. We evaluate the Flash flooding protocol on both a 48-node wireless sensor network testbed and in a trace-based simulator. Our results indicate that the Flash flooding protocol can reduce latency by as much as 80%, achieving flooding latencies near the theoretical lower bound without sacrificing coverage, reliability or power consumption.

Abstract-Polling schemes are an important class of medium access control (MAC) protocols for wireless local area networks (WLANs). A major drawback of these schemes is their inefficiency when only a small number of mobile stations have packets to transmit. This inefficiency is due to the polling of mobile stations with no packets to transmit, which delays the transmissions of mobile stations with packets. In this paper, we suggest a new polling MAC which exploits the capture phenomena and enables simultaneous polling and transmissions of information packets. Mathematical analysis and simulation results show that the new MAC overcomes the above inefficiency considerably, and thus it is more efficient in the sense that it enables higher throughput and a lower access delay. For example, we show scenarios in which the average access delay is reduced by about 30% and the throughput increases by 66%-75%.
