An asynchronous medium access control (MAC) duty-cycled protocols have higher energy efficiency and lower packet latency than synchronized ones due to reduced idle listening. Moreover, they provide efficient utilization of energy supplied to mobile sensors. They are considered very important in MAC protocols due to the adverse effects of hidden terminals which causes energy consumption in sensor networks. Therefore, in this paper, the impact of hidden terminals on the performance of an asynchronous duty-cycled MAC protocol X-MAC for vehicle-base sensor is investigated via analysis and simulations. We propose a Markov model to analyze the quality-of-service (QoS) parameters in terms of energy consumption, delay, and throughput. Our analytical model provides QoS parameter values that closely match the simulation results under various network conditions. Our model is more computationally efficient and provides accurate results quickly compared with simulations. More importantly, our model enables the designers to obtain a better understanding of the effects of different numbers of mobile sensor nodes and data arrival rates on the performance of an asynchronous MAC duty-cycled protocol.

Evaluation of a Duty-cycled Protocol for TDMA-Based Wireless Sensor Networks Hasan, Mohammed Zaki; Al-Turjman, Fadi; Al-Rizzo, Hussain (2016-09-09) Contention-free Medium Access Control (MAC) protocols in Wireless Sensor Networks (WSNs) have higher energy efficiency and lower packet latency than contention-based ones due to reduced idling and allow efficient utilization of energy supplies of sensors. This paper presents evaluation the performance of Time Division Multiple Access (TDMA) dutycycled MAC for multihop WSNs. We propose a semi-Markov chains by considering power consumption in different operational models to analyze the Quality of Services (Qo...
An energy aware fuzzy approach to unequal clustering in wireless sensor networks Bagci, Hakan; Yazıcı, Adnan (2013-04-01) In order to gather information more efficiently in terms of energy consumption, wireless sensor networks (WSNs) are partitioned into clusters. In clustered WSNs, each sensor node sends its collected data to the head of the cluster that it belongs to. The cluster-heads are responsible for aggregating the collected data and forwarding it to the base station through other cluster-heads in the network. This leads to a situation known as the hot spots problem where cluster-heads that are closer to the base stati...
Evaluation of Terahertz Channel in Data Centers MOLLAHASANİ, Shahram; Onur, Ertan (2016-04-29) Designing data center network topologies with the objective of minimizing cost, increasing bisection bandwidth and decreasing latency is a difficult problem. The solutions in the literature mainly concentrate on wired networks and minimizing wiring costs thereof. Only a few proposals address the benefit of employing wireless communications in data centers due to spectrum and bandwidth limitations of current wireless communication technologies. By using terahertz communication in a data center as a complemen...
Implementation of the heed clustering protocol with sleep scheduling in tinyos 2 on a wireless sensor network testbed Özkan, Canay; Uysal Bıyıkoğlu, Elif; Department of Electrical and Electronics Engineering (2013) Energy efficient operation is often critical for wireless sensor networks (WSN), because network nodes operate on limited batteries. The aim of this thesis is to realize an implementation of an energy-efficient, scalable and competitive clustering protocol, HEED on MICAz motes using TinyOS 2 with further energy-efficiency enhancements. A working testbed is constructed, on which the network organizes itself to send periodic sensor measurements to a central station. In order to control overall energy consumpt...
AI for dynamic packet size optimization of batteryless IoT nodes: a case study for wireless body area sensor networks Tabrizi, Hamed Osouli; Al-Turjman, Fadi (Springer Science and Business Media LLC, 2020-10-01) Packet size optimization, with the purpose of minimizing the wireless packet transmission energy consumption, is crucial for the energy efficiency of the Internet of Things nodes. Meanwhile, energy scavenging from ambient energy sources has gained a significant attraction to avoid battery issues as the number of nodes increasingly grows. Packet size optimization algorithms have so far been proposed for battery-powered networks that have limited total energy with continuous power availability to prolong thei...
