摘要/Abstract

摘要： 无线纳米传感器网络是一种有着重要潜在应用的新兴传感器网络。考虑到纳米传感器的极低处理能力,研究人员提出了具有极低复杂度的基于TS-OOK的接入控制方案。针对该方案存在的数据比特发送会连续冲突及吞吐量较低这两个不足,设计了3种改进型TS-OOK方案:周期固定带宽均分接入控制方案、周期倍增带宽均分接入控制方案和支持优先级的接入控制方案。这3种方案都通过接入节点与中继节点之间的简单控制包交互来实现冲突避免。性能分析表明这3种方案具有更高的吞吐量和更低的传输时延。

Abstract: Wireless nanosensor networks(WNSNs) are a new type of sensor networks which have some very important and promising applications.Considering the severely low computation capability of nanosensors,the TS-OOK based medium access control(MAC) mechanism with very low computation complexity was proposed.Aiming to eliminate the defects of TS-OOK based MAC that the continuous bit collision may happen and the throughput is low,this paper presented three improved TS-OOK based MAC mechanisms:period-fixed and bandwidth-fair MAC,period-doubling and bandwidth-fair MAC,and priority-aware MAC.All three mechanisms achieve no collision through a few transmissions of control frames between access nodes and relay node.Performance evaluation shows that the enhanced MAC mechanisms have higher throughput and lower transmission delay.

Key words: Wireless nanosensor networks,Access control,Collision avoidance,High throughput
