In wireless sensor networks, many protocols assume that if node A is able to interfere with
node B's packet reception, node B is within node A's communication range. It is also …

TDMA has been proposed as a MAC protocol for wireless sensor networks (WSNs) due to its
efficiency in high WSN load. However, TDMA is plagued with shortcomings; we present …

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 …

We describe HyMAC, a new hybrid MAC layer protocol for wireless sensor networks that is,
to the best of our knowledge, the first effort to combine the strengths of both TDMA and …

Nodes in sensor networks often encounter spatially-correlated contention, where multiple
nodes in the same neighborhood all sense an event they need to transmit information about …

This paper presents C-MAC, a new MAC protocol designed to achieve high-throughput bulk
communication for data-intensive sensing applications. C-MAC exploits concurrent wireless …

When the data rates in sensor networks are comparable to the available channel bandwidth,
traditional randomized access schemes face the problem of energy inefficiency and reduced …

A wireless transmitter learns of a packet loss, infers collision, only after completing the entire
transmission. If the transmitter could detect the collision early (such as with CSMA/CD in …

Wireless sensor networks (WSNs) emerge as underlying infrastructures for new classes of
large-scale networked embedded systems. However, WSNs system designers must fulfill the …

The traffic-adaptive medium access protocol (TRAMA) is introduced for energy-efficient
collision-free channel access in wireless sensor networks. TRAMA reduces energy …
