Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
This paper deals with the radio propagation models predominantly used for the 4th Generation (4G) of cellular networks generally known as Long Term Evolution (LTE). It is necessary to study the radio wave propagation models at the development level of any wireless communication network or system. A comparative analysis is made among various radio propagation prediction models to assess the appropriate...
Differential dual hop relay based system has been introduced to solve the coverage problem. However, fading channel is the weak link of any wireless system. Generalized Gamma (GG) distribution is one of the fading models of wireless communication. However, GG fading channel is not available in any of the software packages. This research paper presents BER analysis of differential dual hop relaying...
This paper presents the automated irrigation system with enhanced water conservation, using weather forecast and concept of wireless sensor networks. Each node consisting of soil moisture, smoke and temperature sensors communicates with the coordinator, using ZigBee protocol, which then sends updates to the farmer via SMS using GSM protocol. Hargreaves equation for reference evapotranspiration has...
Wireless sensor network (WSN) is a network which includes spatially distributed autonomous devices using sensors to monitor environmental or physical conditions. WSN is emerging as popular and essential ways of providing pervasive computing environments for numerous applications. The sensor nodes are constrained in terms of energy and therefore energy consumption and extending network lifetime is...
Routing algorithms in Mobile Ad hoc Networks like DSR, AODV use flooding as the primary mechanism for discovery of routes in the network. In flooding, each node forwards flood packets to its neighbors so as to ensure that the packets reach the intended destination. Forwarding of redundant flood packets create extra overhead on network bandwidth. However, only a subset of nodes need to forward the...
In wireless communication, physical layer security is widely used for secure communication between the transmitter and the receiver. In this paper, the secrecy performance of two cooperative schemes, decode-and-forward (DF) and amplify-and-forward (AF) relays is investigated in a single hop wireless relaying system. The achievable secrecy rate is investigated with these two types of relays under the...
Higher data rate transmission over longer distances is the need of this era where a huge number of communication users are being added up on a daily basis. This is not a easy task due to presence of fiber impairments which are of two types linear and non-linear. Dispersion occurs due to longer distances and high transmitting power of the light signals which ultimately degrades the received signal...
Selection of appropriate detection threshold (λ) is a very critical task in energy detection scheme based cognitive radio (CR) system. λ is mainly selected by using two principles called as constant detection rate (CDR) in which λ is calculated by taking fixed value of probability of detection (Pd) and constant false alarm rate (CFAR) in which λ is calculated by taking fixed value of probability of...
