Abstract
Wireless sensors networks (WSNs) are increasingly being used in many application that ranges
from Military surveillance to environmental monitoring, seismic monitoring, disaster monitoring
and many more.
The bigger the scale of deployment of Wireless sensor networks, the higher the number of
sensors deployed to monitor a target area that would consequently have a number of network
bottleneck zones which will vary depending on topology and other factors.
Power consumption is one of the major constraints facing the design and deployment of wireless
sensor networks. The paper in review offered a power saving mechanism using network coding
and duty cycling in the bottleneck zone of WSNs.
This paper shall provide a generic overview of Wireless Sensor Networks, critique the proposed
mechanism for saving power consumption as well as explore other mechanisms or method of
having an energy efficiency in WSN bottleneck zones.

1. Introduction
A Wireless Sensor Network (WSN) as evident in its name is a wireless network that is made
up of autonomous sensing devices distributed in a target area where data is to be collected. A
WSN is a network that serves as a bridge between a physical network-WAN, LAN and a
virtual worlds. In other words, there is a gateway that provides wireless connection to a wired
network and other nodes in the WSN.

The development of WSNs was inspired by military applications, notably surveillance in
conflict zones1. There are a number of other applications that Wireless Sensor Networks are
being used, to name a few of them;
• Monitoring of environment –Air, Soil, Water
• Asset Tracking
• Rapid emergency Response
• Structuring monitoring – Buildings, Bridges
• Perimeter Security and Surveillance
• Process Monitoring

WSNs are expected to be major components in the Internet of things (IoT) and the Web of things
(WoT) thanks to low-w cost hardware miniaturization and advances in wireless communication2.
