基于跨层竞争的多跳无线传感器网络同步MAC协议

Ripudaman Singh, Brijesh Kumar Rai, Sanjay Kumar Bose

摘要:

最近设计的跨层竞争为基础的同步MAC协议,如PRMAC协议,无线传感器网络(WSNs),使一个节点调度多跳传输的多个数据包在一个周期。然而,这些系统在相同的数据传输调度窗口(即,数据窗口)中容纳请求发送数据过程和确认发送数据过程。这减少了数据窗口中的多跳流建立的长度。在多跳场景中,这降低了分组传递率(PDR)和端到端传输延迟(E2 ETD)。在本文中,我们提出了一个跨层竞争的同步MAC协议,它容纳在数据窗口中的请求发送数据的过程和确认发送数据的过程中的睡眠窗口,以提高效率。我们评估我们提出的协议,通过ns-2.35模拟和比较其性能与PRMAC协议。结果表明,在多跳的情况下,提出的协议优于PRMAC的E2 ETD和分组交付率(PDR)。

英文摘要:

Recently designed cross-layer contention based synchronous MAC protocols like the PRMAC protocol, for wireless sensor networks (WSNs) enable a node to schedule multi-hop transmission of multiple data packets in a cycle. However, these systems accommodate both the request-to-send data process and the confirmation-to-send data process in the same data transmission scheduling window (i.e. data window). This reduces the length of the multi-hop flow setup in the data window. In a multi-hop scenario, this degrades both the packet delivery ratio (PDR) and the end-to-end transmission delay (E2ETD). In this paper, we propose a cross-layer contention based synchronous MAC protocol, which accommodates the request-to-send data process in the data window and the confirmation-to-send data process in the sleep window for increased efficiency. We evaluate our proposed protocol through ns-2.35 simulations and compare its performance with the PRMAC protocol. Results suggest that in multi-hop scenario, proposed protocol outperforms PRMAC both in terms of the E2ETD and the packet delivery ratio (PDR).
