“…The simulation experiments are carried out based on the following assumptions: The static sensor nodes are uniformly and randomly deployed in a 750 × 750 m 2 area. Each static sensor node is mounted with an antenna having eight sectors. Each individual sector antenna is assumed to be a rectangular patch antenna array (RPA) . The RPA has a peak gain of 2.65 dBi, a beamwidth of 45° and a communication range of 135 m . The sensor node receives beacon packets only if it lies inside the communication range of the sector antenna and if the receiver sensitivity is above −95 dBm, which is the typical receiver sensitivity of CC2420 radios used in WSN motes such as MicaZ . In SAND and MuND protocols, the sector‐switching interval for the token holder and non‐token holder nodes are set at 4Δ t and 32Δ t , respectively. In direct and indirect COND protocols, the fastest sector‐switching interval is set to 4Δ t and slowest switching interval is set to 32Δ t . For the proposed MuND protocol, four tokens are deployed in the network concurrently to initiate the process of neighbor discovery. …”

Directional sensor networks (DSNs) can significantly improve the performance of a network by employing energy efficient communication protocols. Neighbor discovery is a vital part of medium access control (MAC) and routing protocol, which influences the establishment of communication between neighboring nodes. Neighbor discovery is a challenging task in DSNs due to the limited coverage provided by directional antennas. Furthermore, in these networks, communication can only take place when the beams of the directional antennas are pointed toward each other. In this article, we propose a novel multiple token‐based neighbor discovery (MuND) protocol, in which multiple tokens are transmitted based on an area exploration algorithm. The performance of the protocol is evaluated using the Cooja simulator. The simulation results reveal that the proposed MuND protocol achieves lower neighbor discovery latency, with a 100% neighbor discovery ratio, and has a relatively low communication overhead and low energy consumption.

“…For multiband operations, fractal antennas are used [6]. Similar geometry of patch when connected with a single feed line is called array [7]. Various performance parameters of the antenna like scanning the beam of an antenna system, directivity and gain are improved by using array technology in antenna communication [8].…”

“…From the literature, it is clear that rectangular antenna array is designed at a frequency of 2.5 GHz with gain of 2.648 dB [7]. A carpet antenna array operates at five frequencies 6.29 GHz, 6.9 GHz, 7.46 GHz, 8.48 GHz and 11.07 GHz with maximum gain of 5.48 dB [10].…”

A new technique which is a combination of fractal antenna and array antenna is presented to design Plus Slotted Fractal Antenna Array (PSFAA) in this paper. PSFAA with corporate feed operates at 2.5 GHz frequency. PSFAA is designed on FR4 substrate material with permittivity 4.4 and height 1.6 mm. PSFAA is designed up to 2nd iteration. High Frequency Structure Simulator (HFSS) software is used for simulation of PSFAA. The proposed antenna array operates at three bands with five frequencies 2.5 GHz, 4.1 GHz, 6.9 GHz, 7.4 GHz and 8.2 GHz. Simulated Return losses results of proposed PSFAA are −22.15 dB, −19.44 dB, −25.21 dB, −10 dB, −12.45 dB at above frequencies respectively. It has a gain of 9.22 dB at resonant frequency 2.5 GHz whereas conventional antenna array has a gain of 5.15 dB at resonant frequency 2.5 GHz. Return losses and gain of PSFAA also improved from conventional antenna array at various resonant frequencies.

This paper presents a four-element linear array composed of E-shaped microstrip antennas designed to switchedbeam application in ISM (Industrial, Scientific and Medical) radio band. Particle Swarm Optimization (PSO) algorithm is used to optimize four different sets of amplitude and progressive phase shift to achieve four distinct radiation patterns controlling the major lobe direction and sidelobe level. For this application, two restrictive approaches are presented for the implementation of PSO in order to guide the algorithm to feasible solutions.
