Performance enhancement of IEEE 802.15.4 by employing RTS/CTS and frame concatenation

Impact of Using CSS PHY and RTS/CTS Combined with Frame Concatenation in the IEEE 802.15.4 Non-Beacon Enabled Mode Performance

“…In this work we assume that the BE is not incremented since we are assuming ideal conditions. Table 2 from [11] summarizes the key parameters for IEEE 802.15.4 both employing and not employing RTS/CTS with frame concatenation in the 2.4 GHz band, by considering the DSSS PHY layer with the O-QPSK modulation (250 kb/s). IEEE 802.15.4 [8] nodes support a maximum over-the-air data rate of 250 kb/s.…”

“…In a normal transmission, for every DATA packet sent an ACK must be received, as shown in Figure 5. Details on the analytical model for the maximum throughput and minimum delay are given in [11].…”

Cross Layer Design for Wi-Fi Sensor Network Handling Static and Dynamic Environment Using Local Automate Based Autonomic Network Architecture

“…The network need to be made smart and should consider blind learning increasing probability of occurrence as discussed in [2]. Thus, performance with frame concentration can be increased leading to new opportunities with routing leading to lesser collision and energy consumption [3][4][5].…”

“…The process looks simple if the area is not set as a constraint in using Wi-Fi. The collision and congestion can be easily avoided with larger space and high bandwidth compared to UWB, Bluetooth or even ZigBee [1][2][3][4][5].…”
