Multifrequency 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 order to avoid transmission's collisions and improve network performances in wireless
mesh networks (WMNs), a reliable and efficient medium access control (MAC) protocol and …

Capacity is one fundamental problem in wireless Ad hoc networks. Deploying directional
antennas to wireless networks can reduce interference among concurrent transmissions and …

This paper proposes ARM, an receiver-initiated MAC protocol with duty cycling to tackle
control channel saturation, triple hidden terminal and low broadcast reliability problems in …

Cognitive MAC protocols are designed to efficiently utilize the spectral resources without
affecting the performance characteristics of the primary users. The use of spectrum …

In this paper, we study the multi-channel exposed terminal problem in multi-hop wireless
networks. We first explain how the multi-channel exposed terminal problem occurs. We then …

As ZigBee networks operate on the license-free 2.4 GHz Industrial, Scientific, and Medical
(ISM) frequency band, coexistence issues arise because many other wireless technologies …

A multi-hop mobile ad hoc network (MANET) is generally configured as a peer-to-peer
network with no centralised hubs or controllers that coordinate channel resources. Nodes in …

Wireless communication has become the fastest growing area in the communication
industry. The demand for using this medium ranges from security, military, Internet and …
