“…Average residual energy of all nodes is gathered by passing a RREQ between them. [35][36][37][38] The source initiates the process by broadcasting RREQ packet. Each node receive RREQ wait for a predetermined amount of time to wait for copies of the same RREQ, update energy field with current residual energy and pass the query to its downstream neighbors.…”

In Internet of Things (IoT) the nodes collaborate over a network in multihop manner and relay data toward IoT gateway that is ultimately connected to an IP network. The conventional multihop routing protocols assume that all nodes behave truthfully when they receive packets for downstream network but in reality, the IoT relaying nodes avoid message forwarding. The main reason of selfish behavior of nodes is the limited battery power. Many such nodes have limited battery constraint so these nodes may become selfish to save their energy.These nodes need to be encouraged to cooperate in order to increase network life time instead of just trying to increase node's own benefits. This paper discusses energy aware zone-based routing technique that employs game theory to enhance nodes' cooperation and energy efficiency. The nodes follow a path with highest average energy for communication and provide collective support, hence the network life time is increases. For comparative analysis, simulation is performed for the proposed technique along with the existing techniques. The results show betterment in throughput, packet delivery ratio, and network life time.

“…Interference is estimated by incorporating Bayesian estimator and using it together with Channel bandwidth; following this, the available ELC is then deduced. Potential candidate links are selected by comparing ETL with ELC . These candidate links are bifurcated for choosing highly critical links by also taking into consideration the ripple effects.…”

With the introduction of service-centric applications, the provision of quality of service (QoS) would be a challenge in both classical as well as IoT Networks. 1 The value can be added by monitoring these networks in priority areas and spontaneously levelling the traffic, so that network congestion could be avoided. 2,3 Wireless Mesh Networks (WMNs) are gaining in attraction for metropolitan operations as well as being considered successful for IoT communication. Typically, a wireless mesh network is composed of access points, called Mesh Routers (MRs), which interwork hops to hop to form a larger backhaul network.However, these MRs perform additional functionalities as compared to traditional routers, eg, self-healing. The MRs are usually statically placed and of fixed transmission power in contrast to the classical routers used in ad-hoc networks, which typically vary. Hence, in WMNs', interference can be more controlled. [4][5][6][7][8][9] Similarly, MRs in WMN can have multiple radios and thus interference estimation should be based on all radios, which does not usually pose a difficulty in ad hoc networks as routers are equipped with only a single radio. 10 Hence, a comparatively better performance and throughput can be achieved in WMN against ad-hoc networks. However, MRs equipped with multiple radios can also experience some complexities as parallel transmissions in close proximity cannot occur on the same channel at the same time. Assigning each radio, a different channel is practically not possible as this may result in logical disconnection of the network topology. 11There are 3 non-overlapping channels in IEEE 802.11b that are least interfered eg, channels 1, 6, and 11. [12][13][14][15] Besides the fact that the number of available channels is usually less than the number of radios in proximity, this paper discusses the problem of assigning a limited number of Concurrency Computat Pract Exper. 2020;32:e5650.wileyonlinelibrary.com/journal/cpe

“…For instance, the transmitted signals are susceptible to a variety of impairments, such as inter-symbol interference (ISI), doppler shift (DS), and multipath fading. All of these things hurt the recovered signals and tend to slow down and limit the amount of data that can be sent and received during data communication [1]. It is imperative to reduce the negative effects of channel-induced impairments in order to boost the data transfer rates that can be achieved during transmission.…”

In recent years, artificial neural networks (ANNs) have grown a lot and helped solve numerous problems in wireless communication systems. We have evaluated the performance of the Bidirectional-Long-Short-Term-Memory (Bi-LSTM) recurrent neural networks (RNNs) for joint blind channel equalization and symbol detection using a variety of activation functions (Afs) for the gate units (sigmoid) of Bi-LSTMs without requiring any prior knowledge of channel state information (CSI). The performance of Bi-LSTM networks with different AFs found in the literature is compared. This comparison was carried out with the assistance of three different learning algorithms, namely Adam, rmsprop, and SGdm. The research findings clearly show that performance, as measured by equalization accuracy, can be improved. Furthermore, demonstrate that the sigmoid gate activation function (GAF), which is commonly used in Bi-LSTMs, does not significantly contribute to optimal network behavior. In contrast, there are a great many less well-known AFs that are capable of outperforming the ones that are most frequently utilized.
