- E-CSMA: Supporting Enhanced CSMA Performance in Experimental Sensor Networks Using Per-Neighbor Transmission Probability Thresholds
- A transmitter in a wireless network that uses CSMA, a simple carrier sensing-based MAC protocol, to determine the likelihood of successful packet reception at the intended receiver can easily be misled. At the same time, CSMA variants and hybrid MAC protocols based at least in part on carrier sensing have...

- On Lower Bounds for MAC Layer Contention in CSMA/CA-Based Wireless Networks
- Wireless LANs operating within unlicensed frequency bands require random access schemes such as CSMA/CA, so that wireless networks from different administrative domains for example wireless community networks may co-exist without central coordination, even when they happen to operate on the same radio channel. Yet, it is evident that this lack...

- Z-MAC: A Hybrid MAC for Wireless Sensor Networks
- This paper presents the design, implementation and performance evaluation of a hybrid MAC protocol, called Z-MAC, for wireless sensor networks that combines the strengths of TDMA and CSMA while offsetting their weaknesses. Like CSMA, Z-MAC achieves high channel utilization and low-latency under low contention and like TDMA, achieves high channel...

- SPACES: A Distributed Fairness Algorithm for Bus-Based Metropolitan Optical Network
- In metropolitan optical networks, the fairness issue has mostly been analyzed with regard to synchronous transmission (i.e., slotted WDM ring). In this context, the paper focuses on the performance of asynchronous CSMA/CA protocol with variable packet sizes. The paper examines the fairness issue arising between ring nodes sharing a common...

- Adaptive CSMA for Scalable Network Capacity in High-Density WLANs
- Demand for mobile computing devices is unlikely to ebb any time soon. As individuals and businesses continue to use more throughput-hungry applications, High-Density Wireless Local Area Networks (HD-WLANs) designers will need to devise ways to improve network capacity by maximizing special reuse of channels. Tests by Intel researchers show that...
