Transmission Power Control in Single-hop and
Multi-hop Wireless Sensor Networks
Abstract—A major challenge in wireless sensor network (WSN)
deployment is to minimize sensor node’s energy consumption
to prolong the lifetime of the finite-capacity batteries. Power
control is one of the main techniques used to conserve energy in
wireless sensor networks. In this paper we provide an efficient
power control scheme for WSNs based on Telosb platform
which is IEEE 802.15.4 standard compliant. Our simulation and
numerical results illustrate that energy spent to transmit a packet
in network system using short-range multi-hop path does not
necessarily save energy as suggested by some researchers [1].
However, in a single-hop we can save energy by transmitting at
lower transmission power levels while still maintaining reliable
connectivity, resulting in up to 23% reduction in the total network
energy consumption.

I. INTRODUCTION
Sensor networks are distributed networks made up of
small sensing devices equipped with a processor, memory
and the capability for short-range wireless communication.
Recently, ad hoc WSNs have gained tremendous attention
in research communities and commercial applications. This
has been partly due to ad hoc wireless networks’ capability
to establish connectivity without the need for pre-existing
infrastructure, and the fact that these networks are envisioned
to support a wide range of embedded applications. It is also
worth mentioning that the decrease in the size and cost of
sensors has also played a part in increasing the use of WSNs
for applications that would not have been considered feasible

The outcome of this research is recharge Smartphone batteries whenever Wi-Fi connectivity is available and accessible. And not to worry
Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.
Also, it requires a fast and secure communication to monitor real-time connection status to act as Energy Manager. [SANCHEZ]

Wireless local area networks (WLANs) have the potential to improve the flexibility, productivity, and the quality of work life of an enterprise (Sage Research Staff, 2001). Berean Institute is a typical two year college with about a staff of sixty eight employees and 250 students per semester. Berean teaches cosmetology, barbering and the latest software and hardware technology, which is located in Philadelphia, Pennsylvania. Berean currently has two locations in the Philadelphia area and using a Local Area Network (LAN).
It started with modernizing the health care systems with the introduction of Electronic Medical Records (EMR). EMR brought much digitization in the field of health care which resulted in great improvements at the hospitals, patient care methodologies and medication [2]. Since the recent past, sensors play a vital role in the field of health care. Body Sensor Network (BSN) is an amalgamation of wireless wearable smart devices. Such devices are meant to be worn by the chronic patients and the wireless smart devices transmit the symptoms to the remote location based on the configurations [3].
We consider a wireless sensor network with N = 100 nodes distributed randomly in 100m X 100m field. A gateway node is deployed in the centre of the sensing field. The BS is located far away from the sensing field. Both gateway node and BS are stationary after deployment. We consider packet size of 4000 bits. We compare our protocol with LEACH protocol. To assess performance of our protocol with LEACH, we ignore the effects caused by signal collision and interference in the wireless channel. Table 1 shows the radio parameters used in our
In this paper review, the main challenges of the UWSN MAC protocol design are introduced. Then the related works of existing reliable MAC protocols for UWSN are reviewed and summarized.

Wireless technology has come from the basics of cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with technology forever revitalizing. Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing wireless Internet at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly via a router.
The Internet of Things (IoT) is the network of physical objects accessed through the Internet. The Network of interconnected objects harvests information from the environment (sensing) and interacts with the physical world (actuation/command/control), uses existing Internet standards to provide services for information transfer, analytics, applications and communications (Jiong et al. 2012).
