“…By avoiding collisions during the DATA phase and eliminating the hidden-terminal problem, Robcast provides a useful building block for applications with reliability requirements. Simulations show that Robcast's overhead is small and has the least total packet loss among BEMA [12], BSMA [34], BMMM [31], and CSMA/CA [1].…”

“…However, resource limitations of WSNs make the implementation of a separate radio/frequency difficult to achieve. Recently, Busy Elimination Multiple Access (BEMA) protocol [12] adopted BTMA for WSNs by using time synchronized rounds across all nodes (similar to the rounds in Robcast) to allocate a control channel in the time domain instead of in the frequency domain. The disadvantages of BEMA compared to Robcast are its need for finer-grain RCD for performing busy elimination, its vulnerability to certain obstacle arrangements, and its high energy consumption due to the large number of nodes transmitting busy packets in the control phase.…”

Empirical studies show that wireless sensor networks (WSNs) are extremely prone to the hidden terminal problem. As much as 50% of packet losses have been blamed to the hidden terminal problem under bursty communication. Current protocols use RTS-CTS handshakes to avoid collisions and alleviate the hidden terminal problem for unicast communication. However, it is not possible to directly or efficiently generalize this approach to broadcast communication. Motivated by this problem, we propose Robcast, a round-based self-stabilizing protocol for reliably broadcasting data using receiver-side collision detection feedback. The singlehop level reliability of Robcast can form a building block on which future applications and protocols can be designed for WSNs.

In dynamic wireless ad hoc networks (DynWANs), autonomous computing devices set up a network for the communication needs of the moment. These networks require the implementation of a medium access control (MAC) layer. We consider MAC protocols for DynWANs that need to be autonomous and robust as well as have high bandwidth utilization, high predictability degree of bandwidth allocation, and low communication delay in the presence of frequent topological changes to the communication network. Recent studies have shown that existing implementations cannot guarantee the necessary satisfaction of these timing requirements. We propose a self-stabilizing MAC algorithm for DynWANs that guarantees a short convergence period, and by that, it can facilitate the satisfaction of severe timing requirements, such as the above. Besides the contribution in the algorithmic front of research, we expect that our proposal can enable quicker adoption by practitioners and faster deployment of DynWANs that are subject changes in the network topology.

Vehicular ad hoc network (VANET) or inter‐vehicle communication (IVC) provides many brand new and powerful capabilities for transportation system applications. Safety massaging, as one of the capabilities, supports many potential safety applications such as emergency electronic brake lights, lane change warning, pre‐crash warning. These applications require a low latency and high reliability communication service. In this paper, we first analyze these critical requirements. The under‐development 802.11p for VANET is then discussed with respect to those requirements. An extensive research on the enhancements for 802.11 media access control (MAC) is conducted in order to show their suitability for safety applications. As a conclusion, a realistically feasible MAC enhancement scheme is still needed to achieve the high performance requirements and the compatibility. Copyright © 2008 John Wiley & Sons, Ltd.
