Wireless sensor networks are widely used for healthcare applications. A new field known as wireless body area networks (WBAN) has emerged to support this area. An energy efficient medium access control (MAC) protocol can increase the performance of such a network. The major requirements for a WBAN MAC protocol are energy efficiency and low delay. In this paper, we propose a MAC protocol for WBAN using...
Wireless Sensor Network (WSN) has been widely used in many important areas. MAC protocols have a significant effect on the function of WSN. This paper introduced various important MAC protocols, analyzed the fundamental mechanism of each MAC protocol in details, and compared the characteristics and performances of each MAC protocol. Finally, the future research strategies and trends of MAC protocols...
Plant automation and control are mission-critical applications and require timely and reliable data delivery, which is difficult to provide using a wireless technology. This is especially more difficult in industrial environments with harsh radio conditions. In this paper we present a dynamic and distributed topology control algorithm for Wireless Sensor Networks for use in performance critical environments...
In monitoring wireless sensor networks (WSNs) with event-driven applications, the generated traffic usually has bursty characteristics when an event occurs. Transient congestion in the networks would increase delay and packet loss rate severely, reducing the network performance greatly. Through the analysis on delay and packet loss rate in congestion, this paper proposes a congestion-aware mac protocol...
In order to improve the efficiency of energy utilization in Wireless Sensor Networks (WSN), an energy-balanced clustering routing protocol (EBC) is proposed. In the protocol, the nodes select cluster heads in a distributed way, the signal intensity is used to control the distance between nodes which are in the same cluster, and the nodes with more remaining energy are chosen as the cluster heads....
