Collision Resolution MAC Protocols for Wireless Ad Hoc Networks
In wireless ad hoc networks, nodes cooperatively form a network without any infrastructure such as a BS/AP (base station or access point). The widely-used contention-based MAC protocol, IEEE 802.11b, is inefficient in multi-hop networks due to the hidden and exposed terminal problems. The most popular schedule-based MAC protocol, TDMA (time division multiple access), is difficult to implement i...
متن کاملEvaluation of a BIBD Based Directional MAC Protocol for Wireless Ad Hoc Networks
The use of directional antennas in wireless ad hoc networks can significantly improve global performance due to a high spatial channel reuse. Nevertheless, its introduction poses new location dependent problems related to the MAC protocol. In this paper, the Balanced Incomplete Block Design theory has been exploited to develop a new MAC protocol for wireless ad hoc networks using directional ant...
متن کاملDesign of multichannel MAC protocols for wireless ad hoc networks
Medium access control (MAC) protocols coordinate channel access between wireless stations, and they significantly affect the network throughput of wireless ad-hoc networks. MAC protocols that are based on a multichannel model can increase the throughput by enabling more simultaneous transmission pairs in the network. In this paper, we comprehensively compare different design methods for multich...
متن کاملCollision Free MAC Protocols for Wireless Ad Hoc Networks based on BIBD Architecture
Wireless Ad hoc networks represent a powerful telecommunication infrastructure that is being exploited for enabling general wireless networking connectivity for a variety of significant applications, e.g., military applications, industrial automation, sensor networks, vehicular networks, applications in case of disaster, etc. The distributed and flexible architecture of wireless ad hoc networks...
متن کاملCSMA/IC: A New Class of Collision-free MAC Protocols for Ad Hoc Wireless Networks
In this paper, we present a new collision-free MAC protocol–Carrier Sense Media Access with ID Countdown (CSMA/IC) for ad hoc wireless networks that can achieve 100% collision-free performance by solving the “hidden terminal” problem and the concurrent sending problem. Compared to CSMA/CA of IEEE 802.11, it also improves the network's performance in decreasing the average delay of packet sendin...
