A novel idea of alternating node operations between Active and Sleep modes in Wireless Sensor Network (WSN) has successfully been used to save node power consumption. The idea which started off as a simple implementation of a timer in most protocols has been improved over the years to dynamically change with traffic conditions and the nature of application area. Recently, use of a second low power radio transceiver to triggered Active/Sleep modes has also been made. Active/Sleep operation modes have also been used to separately model and evaluate performance and availability of WSNs. The advancement in technology and continuous improvements of the existing protocols and application implementation demands continue to pose great challenges to the existing performance and availability models. In this study the need for integrating performance and availability studies of WSNs in the presence of both channel and node failures and repairs is investigated. A framework that outlines and characterizes key models required for integration of performance and availability of WSN is in turn outlined. Possible solution techniques for such models are also highlighted. Finally it is shown that the resulting models may be used to comparatively evaluate energy consumption of the existing motes and WSNs as well as deriving required performance measures.

A Random Access Scheme for Large Scale 5G/IoT Applications
Balevi, Eren; Gitlin, Richard D. (2018-01-01)
The integration of slotted Aloha with power domain non-orthogonal multiple access (NOMA), dubbed slotted Aloha-NOMA (SAN) can emerge as an appealing MAC protocol to be used for Internet-of-Things (IoT) applications over 5G networks. In this paper, SAN is discussed, and its performance is evaluated in detail. The simulation results demonstrate that the maximum normalized throughput can be increased from 0.37, which is the case for slotted Aloha, to 1 by means of SAN. Specifically, this full throughput effici...
A Novel Input Impedance Computation Method for Coaxial Probe Fed Microstrip Antennas by Utilizing Characteristic Modes
Cetin, Metehan; Alatan, Lale (2017-07-14)
A method to efficiently compute the input impedance of the coaxial probe fed microstrip antennas by using characteristic modes is proposed in this paper. The efficiency is achieved by defining a discontinuous source current at the feed location that models the current injected by the probe. The input impedance is simply expressed in terms of modal excitation coefficients and eigenvalues of each mode.
A cross-layer protocol for wireless sensor networks
Akyildiz, Ian F.; Vuran, Mehmet C.; Akan, Ozgur B. (2006-03-24)
Severe energy constraints of battery-powered sensor nodes necessitate energy-efficient communication protocols in order to fulfill application objectives of wireless sensor networks (WSN). However, the vast majority of the existing solutions are based on classical layered protocols approach. It is much more resource-efficient to have a unified scheme which melts common protocol layer functionalities into a cross-layer module for resource-constrained sensor nodes. To the best of our knowledge, to date, there...

An Energy Aware Fuzzy Unequal Clustering Algorithm for Wireless Sensor Networks
Bagci, Hakan; Yazıcı, Adnan (2010-07-23)
In order to gather information more efficiently, wireless sensor networks (WSNs) are partitioned into clusters. The most of the proposed clustering algorithms do not consider the location of the base station. This situation causes hot spots problem in multi-hop WSNs. Unequal clustering mechanisms, which are designed by considering the base station location, solve this problem. In this paper, we introduce a fuzzy unequal clustering algorithm (EAUCF) which aims to prolong the lifetime of WSNs. EAUCF adjusts t...
