We present and evaluate a class of medium access control protocols for wireless digital networks. The presented protocols are stable, they induce good delay characteristics and they possess resistance to feed back errors. We also evaluate a system deploying the IEEE 802.11 protocol, instead. In the presence of relatively tight admission delay constraints, the latter is significantly inferior to...

The design of effective Medium Access Control protocol for ad hoc network is a highly challenging task due to the characteristics of such networks. The medium is shared and unreliable by definition, thus the access mechanism should be robust to channel errors and collisions. Furthermore, all the coordination functions must be totally distributed in a pure ad hoc environment. In this paper we ad...

Managing wireless communication will be the key to effective deployment of large scale sensor networks that need to operate for years. On the one hand, wireless communication is essential (i) to foster collaboration between neighboring sensor nodes to help overcome the inherent limitations of their cheap, and hence inaccurate sensors observing physical events, and (ii) to report those events ba...

In this letter, we propose a Throughput-aimed MAC Protocol with Quality of Service (QoS) provision (T-MAC) for cognitive Ad Hoc networks. This protocol operates based on the Time Division Multiple Access (TDMA) slot assignments and the power control mechanism, which can improve the QoS provision and network throughput. Our simulation results show that the T-MAC protocol can efficiently increase...

The communication channel is a shared resource in networked control systems, and channel access at every instant cannot be guaranteed. In this paper, we propose a novel architecture for control over wireless networks with integrated medium access control (MAC). We evaluate the impact of constrained channel access on the cost of controlling a single plant over a network and establish that the se...

This paper introduces Human Energy Harvesting Medium Access Control (MAC) protocol (HEHBMAC), a hybrid polling MAC suitable for Wireless Body Area Networks (WBANs) powered by human energy harvesting. The proposed protocol combines two different medium access methods, namely polling (IDpolling) and probabilistic contention (PC) access, to adapt its operation to the different energy and state (ac...

In this chapter, we continue the discussion on medium access control protocols designed for wireless sensor networks. This builds upon the background material and protocols presented in Chapter 4. We first present protocols that are based on random access techniques such as Carrier Sense Multiple Access. These include the Sift protocol, the T-MAC protocol and other protocols. The second set of ...

In this paper, the necessity to achieve a capable Medium Access Control protocol subject to bandwidth constraints is considered. As Medium Access Control has an important role on the bandwidth allotment, bandwidth efficiency is one of the main concept in the design of Medium Access Control (MAC) protocols for MANETs. Nodes are placed in an ad hoc manner, when transmitting the packets nodes will...

Efficient MAC protocol has been paramount importance for improving the performance of WSN. In this paper, Boarder Node Medium Access Control (BN-MAC) mobility aware hybrid protocol is introduced for WSN. BNMAC controls overhearing, idle listening and congestion problem to save energy. BN-MAC mechanism is based on novel semi synchronous low duty cycle that takes less time for accessing channel a...

In the current decade, wireless sensor networks are emerging as a peculiar multi-disciplinary research area. Wireless sensor networks are appealing to researchers due to their wide range of application potential in areas such as target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems. However, lower sensing ranges result in dense networks, wh...
