“…Typically, in wireless channels, two nodes are able to communicate together directly 1‐3 . However, sometimes multipath fading and channel damage can bring about the necessity of using an intermediate node to facilitate the completion of communication 4‐7 . The Cooperative relaying concept takes advantage of the presence of different nodes in the vicinity and uses them to aid in finalizing communications 8‐11 .…”

The proposed work analyzes the performance of dual‐hop relaying systems by means of the differential amplify‐and‐forward relaying method. The post‐detection selection combining reception scheme proposed in this article allows receivers to approximate existing fading gain in a branch by using previously received samples to achieve a cooperative diversity at cases that exclude the need of having explicit channel estimation. Assuming independent fading channels, tight closed‐form expressions for the system bit error rate and outage probability are ultimately derived considering Nakagami‐m fading channels and additive white Gaussian noise. Different fading parameters were used to plot simulation results.

The deficiencies of regular cooperative relaying schemes were the main reason behind the development of Incremental Relaying (IR). Fixed relaying is one of the regular cooperative relaying schemes and it relies on using the relay node to help in transmitting the signal of the source towards the destination despite the channel’s condition. However, adaptive relaying methods allocate the channel resources efficiently; thus, such methods have drawn the attention of researchers in recent years. In this study, we analyze a two-hop Decode-and-Forward (DF) IR system’s performance via Nakagami-m fading channels with the existence of the several L distinguishable interferers placed close to the destination which diminishes the overall performance of the system due to the co-channel interference. Tight formulas for the Bit Error Rate (BER) and the Outage Probability (OP) are drawn. The assumptions are consolidated by numerical calculations.

“…The wireless sensor network (WSN) consists of a large number of small smart devices called sensor nodes distributed randomly in a remote area for monitoring or controlling such area (Sung and Hsiao, 2013;Darabkh et al, 2016). WSNs have many attractive characteristics such as fast deployment, self-organization, low cost, and fault tolerance.…”

In recent years, Wireless Sensor Networks (WSNs) received great attention because of their important applications in many areas. Consequently, a need for improving their performance and efficiency, especially in energy awareness, is of a great interest. Therefore, in this paper, we proposed a lifetime improvement fixed clustering energy awareness routing protocol for WSNs named Load Balancing Cluster Head (LBCH) protocol. LBCH mainly aims at reducing the energy consumption in the network and balancing the workload over all nodes within the network. A novel method for selecting initial cluster heads (CHs) is proposed. In addition, the network nodes are evenly distributed into clusters to build balanced size clusters. Finally, a novel scheme is proposed to circulate the role of CHs depending on the energy and location information of each node in each cluster. Multihop technique is used to minimize the communication distance between CHs and the base station (BS) thus saving nodes energy. In order to evaluate the performance of LBCH, a thorough simulation has been conducted and the results are compared with other related protocols (i.e. ACBEC-WSNs-CD, Adaptive LEACH-F, LEACH-F, and RRCH). The simulations showed that LBCH overcomes other related protocols for both continuous data and event-based data models at different network densities. LBCH achieved an average improvement in the range of 2-172%, 18-145.5%, 10.18-62%, 63-82.5% over the compared protocols in terms of number of alive nodes, first node died (FND), network throughput, and load balancing, respectively.
