Traffic aware data collection MAC protocol for wireless sensor networks

Abstract: In this paper, we propose a new medium access control (MAC) protocol for wireless sensor networks for periodic data collection. The proposed MAC scheme is specifically designed for wireless sensor networks which have periodic traffic with different sampling rates. In our protocol design, sink determines the time schedule for all other nodes in the network. We discuss the design of traffic aware MAC protocol and provide a comparison with the similar MAC protocols through simulation. Under different traffic generation rate, our protocol outperforms the previous one in terms of energy consumption and packet delay. Simulation results show that our protocol demonstrates up to 35% better performance than that of most recent protocol which is proposed for this kind of application, in respect of energy consumption. Comparative analysis and simulation results show that our design considerably gives a good compromise between energy efficiency and packet latency.

A method for realizing the sequential transmission of data

Abstract: A method for implementing the sequential transmission of uplink data during Qos stream remap is provided An end tag packet is constructed by reserving a bit position 1 in an internetwork protocol (IP) header, the operation is simple and easy to implement, which effectively reduces the processing overhead of the SDAP layer when the receiving end identifies the uplink end tag packet, and can reserve two bits for the SDAP header, so that the size of the QFI field in the uplink SDAP header which is still under discussion can be enlarged by one bit
