Z-MAC: a hybrid MAC for wireless sensor networks
TL;DR: Z-MAC is a hybrid MAC protocol for wireless sensor networks that combines the strengths of TDMA and CSMA while offsetting their weaknesses and achieves high channel utilization under high contention and reduces collision among two-hop neighbors at a low cost.
Journal ArticleDOI
QoS-aware MAC protocols for wireless sensor networks: A survey
TL;DR: This survey observes that instead of providing deterministic QoS guarantees, majority of the protocols follow a service differentiation approach by classifying the data packets according to their type (or classes) and packets from different classes are treated according totheir requirements by tuning the associated network parameters at the MAC layer.
Journal ArticleDOI
TreeMAC: Localized TDMA MAC protocol for real-time high-data-rate sensor networks
TL;DR: The experiments on a 24 node test bed demonstrate that TreeMAC protocol significantly improves network throughput and energy efficiency, by comparing to the TinyOS's default CSMA MAC protocol and a recent TDMAMAC protocol Funneling-MAC.

Heartbeat driven medium access control for body sensor networks
Huaming Li,Jindong Tan +1 more
TL;DR: H-medium-access control (MAC) aims to improve BSNs energy efficiency by exploiting heartbeat rhythm information, instead of using periodic synchronization beacons, to perform time synchronization.

A Lightweight Collaborative Fault Tolerant Target Localization System for Wireless Sensor Networks
TL;DR: A lightweight acoustic target localization system for wireless sensor networks based on time difference of arrival (TDOA) which provided a reliable communication platform where high channel contention was lowered while maintaining high throughput and Errors were detected and eliminated hence acquiring a fault tolerant operation.

Period-controlled MAC for high performance in wireless networks
TL;DR: Simulation results show 10%-50% higher throughput than distributed coordination function (DCF), depending on the number of nodes, while maintaining nearly perfect fairness, and shows how PC-MAC can successfully be applied to complex networks.

Node coloring for dense wireless sensor networks
TL;DR: This research report defines the h-hop node coloring problem, and proves that the associated decision problem is NP-complete, and presents a 3-hop distributed coloring algorithm that is optimized for dense networks.
Journal ArticleDOI
Adaptive energy-efficient registration and online scheduling for asymmetric wireless sensor networks
TL;DR: This paper presents an adaptive energy-efficient registration and online scheduling (AEROS) protocol that exploits application based data flow characteristics to reduce power consumption during self-organization and proposes an organized transmission schedule with risk-free sleeping time.
Proceedings ArticleDOI
Node Coloring in a Wireless Sensor Network with Unidirectional Links and Topology Changes
TL;DR: The proposed SERENA, a node activity scheduling algorithm based on three-hop coloring, takes into account the real wireless environment and so enables substantial performance improvements and the benefits brought by this solution, namely the increase of network lifetime and spatial reuse.

Energy Efficiency of MAC Protocols in Wireless Sensor Networks
TL;DR: The energy efficiency of typical MAC protocols in WSNs is studied systematically using the ns-2 network simulator and their pros and cons are qualitatively compared.
