Ad hoc mobile wireless networks have seen increased adaptation in a variety of disciplines
because they can be deployed with simple infrastructures and virtually no central …

Capacity improvement is one of the principal challenges in wireless networking. We present
a link-layer protocol called Slotted Seeded Channel Hop**, or SSCH, that increases the …

This paper demonstrates how to use multiple channels to improve communication
performance in Wireless Sensor Networks (WSNs). We first investigate multi-channel …

A number of algorithmic and protocol assumptions taken for granted in the design of existing
wireless communication technologies need to be revisited in extending their scope to the …

Multi-frequency media access control has been well understood in general wireless ad hoc
networks, while in wireless sensor networks, researchers still focus on single frequency …

In traditional wireless sensor network (WSN) applications, energy efficiency may be
considered to be the most important concern whereas utilizing bandwidth and maximizing …

This work presents a TDMA based multi-channel MAC protocol called TMMAC for Ad Hoc
Networks. TMMAC requires only a single half-duplex radio transceiver on each node. In …

The ability of newer generations of commercially available radios used on the sensor nodes
to tune their operating frequency over different channels provides an opportunity to alleviate …

Research in the physical (PHY) and medium access control (MAC) layers for dynamic
spectrum access (DSA) and dynamic spectrum sharing (DSS) is still at its infancy. Aspects …

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 …
