Medium Access Control for Opportunistic Concurrent Transmissions under Shadowing Channels

We study the problem of how to alleviate the exposed terminal effect in multi-hop wireless networks in the presence of log-normal shadowing channels. Assuming node location information, we propose an extension of the IEEE 802.11 MAC protocol that sched-ules concurrent transmissions in the presence of log-normal shadowing, thus mitigating the exposed terminal problem and improving network throug...

Energy Efficient Medium Access Control Protocol for Clustered Wireless Sensor Networks with Adaptive Cross-Layer Scheduling

This paper presents an Energy Efficient Medium Access Control (MAC) protocol for clustered wireless sensor networks that aims to improve energy efficiency and delay performance. The proposed protocol employs an adaptive cross-layer intra-cluster scheduling and an inter-cluster relay selection diversity. The scheduling is based on available data packets and remaining energy level of the source n...

A Scheduling-Based Medium Access Control Protocol for Supporting Multi-class Services in Wireless Networks

In this paper, we propose a scheduling-based medium access control (MAC) protocol for supporting multi-class services in wireless networks. The proposed protocol is a centralized MAC protocol which applies a coordinator node (CN) to coordinate the network. Our protocol is composed of a slot-scheduling algorithm called weighted scheduling and a quality of service (QoS) enhanced admission control...
